why does lcd module need sla manufacturer

3D-printing was discovered more than 30 years ago by the original founder of 3D-systems[1]. This first 3D-printer was named stereolithography apparatus and used a laser to cure a light reactive resin. During the years after the discovery, other companies like EnvisionTEC[2] came up with new methods of curing the light reactive resin, by projector, instead of a laser. The last years, companies like Wanhao[3] and Anycubic[4] made resin based 3D-printing accessible for everyone by the introduction of cheaper LCD based 3D-printers.

Laser SLA is based on the original invention, used by companies as 3D-systems, Formlabs, UnionTech[6] and Peopoly Moai[7]. The laser is used to selectively cure the resin, by scanning the surface. The resin cures and becomes a hard plastic at the spots where the laser ‘hits’ the resin.

DLP-SLA is a technique which uses a projector to selectively cure the resin. It is generally a faster printing technique compared to Laser SLA, due to the fact that the projector can expose the whole layer at once, where a laser has to scan to cure the resin. A few single LED’s are in the center of the DLP projector. The light from these LED’s is guided to a DMD chip, which creates the actual curing pattern. This 3D-printing technique is used by companies like EnvitionTEC, Sprintray[8], Atum3D[9], Rapidshape[10], Miicraft[11] and Kudo3D[12]

One of the latest developments in resin 3D-printing is MSLA, also called LCD based 3D-printing. This technique uses an affordable LCD screen to create the mask, eliminating expensive DMD chips that are used in DLP techniques. This technique works by an array of LED’s illuminating on the LCD. The LCD is used as a mask, which creates the curing pattern. The liquid resin turns into a rigid plastic on the spots where the light ‘hits’ the resin. Companies like Wanhao, Anycubic, Sparkmaker[13], Kudo3D, Creality[14], XYZprinting[15], Phrozen[16], and many more.

One of the main drawbacks of Laser SLA techniques is its price for the machines and consumables. This also applies to DLP 3D-printers. DLP printers have another technical disadvantage to keep in mind, the (affordable) DMD chips are usually 1920*1080 pixels, which limits the quality of printing when upscaling the build area. LCD based printing is a lot cheaper compared to the other techniques. These machines are more affordable and also consumables like FEP foil for your resin tray is cheaper.

What most users don’t realize is that the LCD display is also count as a consumable, which should be replaced from time to time. The build area is dependant on each machine and technically it is easier to create a bigger build area, by placing a bigger LCD in the machine.

Not all resins are compatible with the different printing techniques. It is important to read the resin manufacturers datasheets to understand if it is compatible with your 3D-printer. Laser based 3D-printers have a very powerful laser, which would need a slower curing resin to get a stable printing process. While LCD based 3D-printers have a low power LED light source, which works very well with fast curing resins. DLP 3D-printers can be configured in many different ways, making it impossible to predict curing behaviour of the resin without testing.

The Liqcreate resins are developed to work with most techniques. Liqcreate Strong-X, Clear Impact, Deep Blue, Stone Coal Black and Hazard Glow are developed to print on Laser- and DLP based machines, while still working on LCD 3D-printers when exposure times are increased. While the Liqcreate Premium line is developed to print fast on low-power DLP and LCD printers. Read more about the resins here:

Laser, LCD, and DLP are three distinct methods of exposing a light-sensitive resin in layers to cause a cross-linking of liquid polymers, curing the liquid into a solid object. All of these are used within SLA printers, a term used to refer to the stereolithography process. There has been a disturbing trend to refer to LCD printers are “DLP” printer that started when lower price-point manufactures began to use the already-taken “DLP” term for marketing purposes and claiming it was ok because their LCD does light processing using digital signals. Doing so, however, is like calling a gasoline-engine car an electric vehicle – something that it is not – just to confuse consumers into thinking that they are getting something often seen as more desirable but at a lower price.

Laser, (originally L.A.S.E.R as an acronym for Light Amplification by Stimulated Emission of Radiation) uses galvanometer scanners to direct a light beam via vector and raster scanning. The process is fast for smaller object, but get progressively slower when it must draw out more objects. The advantage is a smooth surface finish and compatibility with resins high in polymer content for the strongest resulting parts. An example of desktop laser-based SLAs are the Peopoly Moai and the Formlabs Form-2 printer.

LCD is a variation of SLA that uses a Liquid Crystal Diode display, the same as in most laptops and mobile phones, as a mask. It is also known as MSLA, or masked SLA. A light source is placed on one side, and the resin on the other. Because the entire layer can be exposed at the same time, they are generally faster for printing more or larger objects. Example of LCD-based SLA printers are the Anycubic Photon, Wanhao Duplicator 7, and the EPAX-3D 1X. One reason why LCD still remains on the low end, because the fact that they can simply be manufactured for less cost, is that there is a limited amount of light that can pass through the LCD panel before it overheats and self-destructs. This limits the speed at which printing can take place. To help make up for this lower amount of light exposure, the resin makers increase the monomers and photo-sensitive initiators, with a resulting increase in potential for shrinkage and weaker parts. In reality though, due to advances in resin such as Siraya Labs Blu (the strongest LCD resin I have tested) and eSun Bioresin (the strongest solid-color LCD resin I have tested), some very strong parts can be made – just as strong, if not stronger, than PLA and ABS parts on FDM printers.

DLP uses a digital micro-mirror device in which light is reflected through a projector lens and onto a tank of resin. Because this matrix of mirrors can be well cooled, a lot more light can be directed than with LCD, thus making it the choice of larger, faster, and more expensive printers that can still make use of less sensitive and stronger resins normally reserved for laser. The downside being a higher price point, taller printer size, and sometimes lower resolution because DLP chips tend to max out at 1080P.

But you may ask – why is it not ok to refer to my LCD-based printer as “DLP” when the manufacturer says it has light processing and is digital? The answer is because the term DLP was already taken for a digital micro-mirror projector device, and there would be no distinction between the technologies, both of which are used in resin printers, if you used the same term for both.

The two main types of SLA systems are desktop (prototyping) and industrial printers. Industrial SLA machines can produce more accurate components than their desktop counterparts (and maintain better accuracy over larger builds), and often make use of higher-cost materials. While desktop SLA can achieve tolerances between 150 and 300 microns, industrial printers are capable of tolerances as low as 30 microns for nearly any build size.

One of the limitations of most industrial machines is that they produce parts using a top-down approach resulting in the need for large resin tanks (over 100L). This makes swapping between materials difficult and can increase lead time on parts. This also makes these machines more expensive to maintain.

Compared to desktop printers, industrial machines are designed for repeatability and reliability. They can often produce the same part over and over again and do not need the high level of user interaction that desktop machines typically require.

Overall, SLA’s unique ability to batch produce intricate, customized parts makes it a popular method of manufacturing small parts, low-run production.

There are a wide variety of 3D printers on the market right now. LCD, DLP, and SLA 3D printers all use resin as a way to create prints. But which one is best suited for your needs?

LCD 3D Printers use an LCD display module to project a certain light pattern which is then used to cure resin in the resin vat. LED light is used as the light source while the LCD screen controls the light pattern. Light is emitted from the LED lamp. It then passes through an LCD screen and is absorbed by the resin. An image of each layer is generated on the LCD screen while an entire layer is hardened at once.

SLA 3D printing, or stereolithography, uses lasers as a light source to print out 3D prints. As the laser traces each point in a single layer, the liquid resin hardens in the process.

In each LCD screen, you can calculate the pixel size by dividing the length of the LCD by the number of pixels on the length of the LCD screen. Let’s take Phrozen Sonic Mini 4K as an example, its X resolution (pixel size) is 134.4 mm / 3840 pixels = 0.035 mm.

DLP 3D printers use the same concept as LCD 3D printers; you can calculate the pixel size by dividing the length of the tiny mirrors by the number of pixels present on the DMD.

SLA 3D Printers:For SLA 3D printers, the XY resolution will depend on the average spot size of the laser beam and the increments at which the laser beam is controlled.

LCD 3D Printers:As there are a wide variety of LCD 3D printers on the market, companies are now rushing to create LCD 3D printers that are much more precise and accurate than previously possible. This means that LCD 3D printers are getting close to the accuracy and precision provided by traditional SLA 3D printers with proper calibration components.

SLA 3D Printers:As lasers are used in SLA printing, 3D models printed using this technique tend to be accurate and precise. SLA 3D printers print out models with an even and smooth surface as the laser moves through a continuous path while slowly drawing out each layer.

Though SLA 3D printers can print out smooth models, the price of purchasing such a device could be 3-5 times higher than LCD 3D printers. It also takes much longer to print with an SLA 3D printer as we will explain next. For those looking to print resin miniatures and other similar models at home, it would be more worthwhile to purchase an LCD 3D printer for speed and cost purposes.

LCD 3D Printers:LCD 3D printers are similar to DLP 3D printers in that an entire layer of resin can be cured at once, meaning that it also can print much faster than SLA 3D printers and print out a collection of 3D models in one go.

This is because monochrome LCD screens are designed for the purpose of allowing higher light transmission and higher thermal resistance. This way, 3D printers that use Mono-LCD screens can cure resin at a shorter layer exposure time and have a longer lifetime than Color LCD screens.

DLP 3D Printers:As an entire layer of resin is cured with UV light at once, this means that you can print a large number of tiny models at once while using a DLP printer. The process will be much faster than an SLA 3D printer and even some LCD 3D printers.

SLA 3D Printers:As SLA 3D printers use lasers to trace out the pattern of a single layer before moving onto the next layer, it takes a much longer time to print out each individual model using this type of printing technique.

As SLA 3D printers use a different technique while printing it cannot entirely be compared to the printing techniques of DLP or LCD 3D printers. If you"re looking to print models with speed, it would be better to purchase LCD 3D printers for speed and accuracy purposes as SLA 3D printers print extremely slowly.

LCD 3D Printers: In comparison to other 3D printing techniques, LCD 3D printers are created as an affordable alternative to their 3D printing counterparts. These 3D printers use an LCD panel for printing purposes which can easily be replaced. Moreover, LCD printers can be made to be small, so most LCD 3D printers are desktop-sized which makes them easy to store.

DLP 3D Printers:DLP 3D printers are also more expensive than LCD 3D printers as it requires the use of Digital Micromirror Device (DMD) which tends to be costly as well.

SLA 3D Printers:In terms of cost, SLA 3D printers tend to be more costly than their counterparts: DLP and LCD 3D printers. This is because SLA 3D printers include machines and lasers which tend to be more expensive.

Depending on the brand and type of SLA 3D printer you choose to purchase, the price could range from $3,500 for a basic SLA 3D printer to several hundred thousand dollars for an industrial SLA 3D printer.

While DLP 3D printers print the fastest, these produce models with low resolution and are also more costly than LCD 3D printers. 3D prints can also be easily distorted due to the use of a projector lens.

Though SLA 3D printers prints out resin 3D prints with accuracy and precision through the use of a laser, it prints very slowly, as it can only print one 3D model at a time. In comparison, both DLP and LCD 3D printers are capable of printing out an entire plate of 3D models in one go.SLA 3D printers also tend to be

Even though LCD 3D printers don’t print as fast as DLP 3D printers, it prints with accuracy and precision through the use of an LCD screen and UV lights, producing 3D models with extremely high resolution. LCD 3D printers, especially

When we talk about resin 3D printing—or vat photopolymerization—we are referring to any 3D printing process that uses a liquid resin as its build material and a light source to solidify the liquid resin. As we’ll see, there are different variations on resin 3D printing (i.e. SLA, DLP, LCD), but generally speaking resin printing technologies are incredibly versatile and are used for many types of applications that require a high resolution and fine details. Hobbyists and gamers use resin printing technology to create highly detailed miniatures; jewelry designers use it to create prototypes and patterns for casting; dental labs use it to create patient-specific models and molds; and more.

Stereolithography, also known as SLA, is one of the most widely used 3D printing techniques today. It is also one of the oldest: the first SLA 3D printer was invented in the 1980s by 3D Systems founder Charles Hull. In the SLA 3D printing process, a UV laser “draws” a cross section of a part on a thin layer of liquid photopolymer resin. When the resin is exposed to the UV laser light it is cured and solidifies. From there, another thin layer of resin is applied and the laser process is repeated until a solid 3D printed object is created.

One of the main reasons SLA 3D printing is so popular is its ability to print high-quality isotropic parts with very smooth surfaces. Unlike FDM prints which are porous, SLA parts are also watertight. Additive manufacturing users are also drawn to SLA for its diversity of materials: the technology is today compatible with a wide range of resins, including standard resin, transparent resin, tough resin (ABS-like), flexible resin, biocompatible resin, and filled resin (i.e. ceramic-filled resin).[1]

Over the years many different industries have adopted SLA 3D printing technology, including the medical and dental industries, the jewelry sector, the consumer segment (particularly for product development), and engineering for high-quality prototyping.

Digital Light Printing, aka DLP, is also among the most popular resin 3D printing processes. DLP is similar to SLA in many ways: it too uses a light source to selectively cure layers of liquid resin photopolymer. Unlike SLA, which uses a single UV light to draw on the layers of resin, DLP uses digital projection to expose segments of the liquid resin to light. More specifically, for each new layer of liquid resin, the DLP projection system emits a 2D pattern (the cross section of the 3D model) which cures the entire resin layer at once.

One of the benefits of DLP 3D printing is its printing speed: because the digital projector can cure an entire layer of resin at once, the DLP process can be significantly faster than SLA, which relies on a laser to draw out the 3D model cross section. SLA, however, is typically capable of achieving higher resolutions than DLP.

Like many SLA 3D printers, DLP systems are built on a bottom up approach. This means that the projection system is placed below the vat of resin and the build plate lowers itself into the resin. The digital projector then flashes and cures a pattern onto the layer of resin through the transparent tank. As each layer is printed, the build platform moves up a layer.

Liquid Crystal Display (LCD) 3D printing, sometimes known as masked stereolithography (mSLA), is very similar to DLP 3D printing: both processes use a light source to cure layers of resin material using a bottom up approach. The key difference between the two technologies is the type of light source: DLP uses a digital projector and DMD, while LCD uses a combination of LEDs and an LCD screen. In the LCD printing process, an array of LEDs positioned below the 3D printer resin vat emits light, which is passed through an LCD screen. The LCD screen essentially controls the pattern of the LED lights and enables the resin layers to cure with a high degree of accuracy. Like DLP, the LCD 3D printing process is capable of curing an entire layer at once.

Another difference between DLP and LCD is how the 3D printer resolution is determined. In DLP, the maximum print resolution is influenced by the size of the micromirrors in the DMD. In LCD, the resolution is determined by the number of pixels and the size of the LCD screen. To find the resolution of a LCD 3D printer, you simply have to divide the length of the LCD screen by the number of pixels along the same length.[2]

If you are new to resin 3D printing, the good news is that many SLA, DLP and LCD 3D printers are designed for plug-and-play use. This means it is relatively easy to get the 3D printer up and running. Where things can get a bit more complicated, however, is the material handling. Unlike FDM filaments, which can be stored easily and are safe to touch, photopolymer resins must be handled and stored carefully.

As is the case with any 3D printing material, proper storage ensures the quality and longevity of the material. In the case of 3D printing resins, one of the most important things to remember is that they are sensitive to UV light. They must therefore be stored in opaque containers and preferably in a dark environment. SLA 3D printing manufacturer Formlabs recommends using containers made from HDPE or polypropylene.[3]

First, be sure to wear protective gloves and clothing when handling liquid resin. This will ensure your skin is safe from any irritation that may occur if you spill resin on yourself. For the best protection, chemical-resistant nitrile gloves or neoprene gloves are recommended. If your skin does come into contact with liquid resin, it should be washed thoroughly with soap and water—avoid using alcohol-based cleaners.[3] Wearing eye goggles is also a good idea to protect yourself in case of any resin splashes.

One of the benefits of resin 3D printing technologies is that parts do not require significant post-processing. SLA, DLP and LCD systems are all capable of printing models with smooth surface finishes and fine details. That being said, 3D printed resin parts do need to undergo a cleaning process to remove the sticky uncured resin residue from their surface.

Besides cleaning resin prints, there are a few other post-processing steps to be aware of. Post-curing, for example, is an optional step that further cures 3D printed resin parts and results in superior mechanical properties. Post-curing is a great option when producing functional parts or prototypes that require greater strength and is a requirement for biocompatible resins. Many SLA and DLP 3D printer manufacturers offer dedicated post-curing stations, however it is possible to make your own using a UV light source and rotating platform. It is also possible to post-cure resin prints in the sun.

If your printed part was made with support structures, support removal is an important post-processing step. Support removal is fairly straightforward: after the cleaning process, clip away supports using flush cutters. By placing the cutters as close as possible to the print surface, you will minimize the amount of sanding required to ensure a smooth surface finish. For supports located at delicate junctures, use tweezers to carefully pry them away. If you do need to sand the 3D print to remove support marks, start by using a low grit sandpaper and gradually transition to finer sandpaper. Using strategic support orientations can also minimize the need for support structures and make them easier to remove.

Ultimately, resin 3D printing technologies like SLA, DLP, and LCD are great for producing high resolution prints with good surface quality and fine features. Here are some of the main takeaways about resin 3D printing that we covered:The main difference between resin 3D printing process is the light source used: SLA uses a laser beam, DLP uses digital projection, and LCD uses a combination of LEDs and an LCD screen.

I"m surprised your research hasn"t answered your question, as the concept is relatively simple. You have most of the answer in the question. The missing item is a light source. Usually the source is an array of ultraviolet LED modules. There are resin printers that would not be called LCD printers, as they use computer display projectors to generate both the image and the UV to cure the resin.

The light source that answers your question is visible in the third picture. As noted, the LCD panel blocks the light based on the image to be cured. I think the "uses its own light" is somewhat misleading, unless the builder has found a high-UV output LED LCD panel or is using daylight resins and has configured for long burn-in times.

Digital light processing (DLP) and liquid crystal display (LCD) 3D printing have similarities to stereolithography (SLA) 3D printing; each of these technologies uses a light source to cure the resin. A projector is used to cure photopolymer resins in DLP printing and UV LEDs are projected through and LCD screen for LCD 3D printing.

LCD vs DLP technology: What are the differences between these resin 3D printing technologies? The liquid resin is contained within a vat, or tank, cured against a build platform, which slowly rises out of the tank as the part is formed, layer by layer. These two 3D printing technologies are quite similar, but here is the main difference: the light source.

LCD printing: A UV light coming from an array of LEDs shining through an LCD flashes complete layers at the resin tank. A screen is used to mask the entire image, only revealing the current layer for curing. LCD 3D printing is a cost-effective resin manufacturing technique to get big and detailed functional parts. This 3D printing technology focuses on mass manufacture and large component 3D printing for resin materials thanks to 3D printers with larger build tray developed by Photocentric for example.

In any business transaction, it’s important to know what you’re getting and to trust the entity you’re working with. One way to ensure both of those things happen is to have a service level agreement (SLA) with your supplier. This is especially important in the manufacturing industry, where there are a lot of moving parts and projects can be long and complicated.

A great SLA will outline matters like the process for ordering, revisions, shipment, inventory, obsolescence and lead time expectations, and help keep you on track to meeting your goals. It doesn’t have to be legally binding but it does need to be something both you and your supplier agree upon before starting a project together.

One of the main benefits of an SLA is that it gives each party the opportunity to share its goals for the end product. Whether it’s a simple battery cable assembly or a complex operator interface, your initial goals will likely be different than your supplier’s goals. For example, you might want your supplier to get you the product as quickly as possible. However, your supplier may want to look for cost reduction opportunities within the design. When you share those goals with one another, you have the opportunity to discuss them and make sure they align. If cost reduction sounds like a good idea to you, maybe you’ll offer to give your supplier a little more time to deliver. Or, you can work with your supplier to get this particular order delivered quickly while giving them the opportunity to look at cost reduction options for the next order.

Once you understand each other’s goals for the project, you can further the discussion by laying out expectations. Do you want your supplier to keep you updated on the progress? If so, how often and how would you like it communicated? Does your supplier expect certain information from you along the way? If you know what information your supplier expects from you and when they’ll need it, you can be sure to provide it in a timely manner. And knowing what you expect reduces the need for your supplier to call you with questions, or waste time waiting on answers via email.

With common goals and clear expectations, you and your supplier should be able to sail smoothly through the project with little to no issue. Your supplier can more accurately plan how much space will be needed to build your product, as well as how many people it will take. They will also be able to leverage their supply chain in a manner that meets or exceeds your expectations, helping them deliver the highest quality product to you on time. Your supplier will appreciate the advanced planning and, barring any unforeseen delays, you can plan your operations accordingly — allocating labor and space as necessary to get the finished product to your own customers.

In short, an SLA is a proactive tool that opens up communication lines between you and your supplier. It allows both parties to plan better, maximizing space and labor availability. Your supplier will know exactly what you need and how you expect it to be manufactured, so if any questions come up in the process, your supplier is empowered to make decisions quickly without spending undue time consulting you or your team. An SLA will remove any gray areas and draw a clear line of expectations and deliverables for both you and your supplier.

While your SLA may vary from supplier to supplier, or from product to product, many of the goals and expectations can remain the same. As long as you and your supplier are on the same page from the beginning, you’ll have a great SLA.

If you’re looking for a resin 3D printer there are a few things you will need to consider. If you are coming from traditional FDM printing not much of the knowledge base is transferable to the world of resin 3D printing. Let’s start with the types of resin 3D printers.

SLA 3D printing utilizes two motors known as galvanometers. These motors work as the X and Y axes to rapidly angle two mirrors that direct a laser beam. The laser traces the print much like a traditional FDM printer and hardens the resin where it is traced.

LCD 3D printing is also known as Mask Stereolithography or MSLA. This utilizes a UV light source that shines up into an LCD screen. The LCD screen is used as mask to generate an image of each layer. This hardens the entire layer at a time.

SLA and LCD resin printers are by far the most common of the three for desktop resin printers. For that reason we will be focusing mainly on SLA and LCD printers.

The advantage of SLA printers is that they tend to have better quality due to the finer dimensions of the laser and the laser’s analog movement. For LCD printers, the quality is determined by the resolution of the LCD screen used to mask the UV light. The standard is a 2k resolution LCD screen, but certain printers can be upgraded to a 4k screen which give better detail. Because the LCD screen is made up of pixels, the print will inevitably not be completely smooth but it is not noticeable unless closely examined.

Depending on what you are printing, there are print speed differences between SLA and LCD printers. For small tall objects SLA has an advantage in speed. Because the laser in SLA machines trace the object, the print speed will depend on the size of print in the X, Y and Z. The wider the object, the longer the duration for each layer.  The taller the object, the more layers there are to print.

For LCD printers large short objects have an advantage when compared to SLA. Because it prints an entire layer at a time, the length of the print is solely dependent on the height of the print. This means that if you are utilizing the full build volume, it should print faster than SLA 3D printers.

Due to the components used, SLA printers are generally going to be more expensive than their LCD counterpart. Also, there are a lot more LCD printers to choose from which leads to their lower price due to competition. Here are some of the most popular printers for both SLA and DLP types and their prices to give you an idea of the difference in pricing.

As with any 3D printer, certain parts of the printer are consumable. These parts are different for SLA and LCD variants. We’ll go over these differences and the rough cost of replacing these parts.

A printer that uses resin tanks have a non-stick bottom that helps the print release from the tank when curing the layers. This non-stick layer wears out over time and the whole tank needs to be replaced. The recommended lifetime of the tank is about 1000 - 1300 layers or 1 - 2 liters of resin. The tanks vary in cost but are typically anywhere from $50 to $100. SLA and LCD printers can utilize resin tanks but they are mostly used in SLA printers.

A Printer that uses FEP sheet tanks have a flexible sheet of FEP as the bottom of the tank. This is a non-stick sheet that helps the print release from the tank when curing the layers. Unlike the Resin tanks, the whole tank does not need to be replaced. Only the FEP sheet needs to be replaced. The lifetime of the sheet is similar to the tank version, about 1000 - 1300 layers or 1 - 2 liters of resin. The typical cost is about $10 per sheet. FEP sheets(link this) can be cheaper if purchased in packs.

For LCD 3D Printers the LCD itself is a consumable part. It has a lifespan of approximately 1000 hours of printing. Replacement LCDs run somewhere between $40 to $80.

There are many types and brands of resins available. Typically, the machines cure resin at a 405nm wavelength so any resins that cure in that range will work. Technically, any resin in that range will work for both SLA and LCD printers but there are specific resins made for each. SLA uses a much more powerful UV light than LCD printers so if an SLA resin is used in an LCD printer, it will still cure but the cure times would be incredibly long. If LCD resins are used in SLA printers, the resin will cure too fast and loss of detail will occur.

Both DLP and LCD printers can print one full layer at a time, making them some of the fastest 3D printers available. An entry-level LCD printer costs $200 to $1,000. DLP printers start at $500 for entry-level printers and can go up to $100,000 for commercial use.

DLP is an older, more established technology than LCD printing. Though there are a lot of similarities between the two, the main difference is the light source used to cure the printing resin. DLP uses a high-intensity projector as a light source and directs it with thousands of tiny mirrors. LCD printers replace that setup with an LCD screen to mask the UV light which comes from an array of LED lights.

On the whole, LCD printers are constructed using cheaper components than DLP printers. However, LCD screens have shorter life spans than DLP mirror arrays. Plus, low-end screens tend to let light through in a less-than-uniform manner. This results in varying quality and precision from batch to batch and machine to machine.

DLP and LCD printers both employ liquid resin. DLP uses a high-power and higher-intensity light source that can operate on a wider range of resins. This gives DLP more options in terms of material quality. LCD printers, on the other hand, use low-intensity UV LEDs which require less viscous, fast-curing resins. This limits the types of material that can be used and impact the quality of the final product.

DLP is very accurate in narrow, small-scale prints. This makes it very useful for jewelry or dental implants, where precision is critical. LCD, on the other hand, is inexpensive and very accurate for the price point. This low price point makes it great for hobbyists. LCD is also ideal for when the price is more important than absolute precision. That can be valuable for industrial use, certain dental applications, and manufacturing.

DLP machines are available for hobbyists, professionals, and industrial applications that need large print volumes. LCD is a newer technology and has not caught on as much for industrial use. Therefore, large-volume LCD printers are not yet common, though this capability is gradually improving.

Less expensive versions of DLP and LCD systems can both have problems with surface finishes and print quality. DLP produces distortions on the edges of a print, especially in wide parts. LCD pieces can also come out imperfect due to inconsistencies in LEDs, especially with larger machines and larger prints. Both production methods must be followed by post-processing to finalize the parts’ surfaces. Generally, DLP parts come out with better surface finishes and print quality, especially with higher-end printers.

DLP and LCD are both available at affordable prices. An entry-level DLP printer can be purchased for as low as $500, while professional-grade types start at $2000. LCD printers, on the other hand, are available from $200 to $1,000.

There are a few technologies that are alternatives to both DLP and LCD printers. As an example:Stereolithography (SLA):SLA is a resin-based 3D printing technology known for its accuracy. It is similar to DLP and LCD in its use of photopolymer that is cured via UV light.

A 3D printing technology that shares similarities with LCD includes:LCD vs. SLS: SLS uses a laser to fuse powder into a 3D printed object. This is an established industrial technology that compares to LCD in terms of accuracy and printing speed.

Manufacturers of low-cost 3D printers that use the masked stereolithography (MSLA) process are able to build their machines so cheaply because they’re using repurposed smartphone or tablet LCD panels to mask off the UV backlight. Considering the quality you get out of even the entry-level MSLA resin printers, we certainly aren’t complaining about this bit of thrift. But as [Jan Mrázek] explains in a recent blog post, there’s certainly room for improvement.

The problem is that those repurposed LCD panels are, as you’d expect, color displays. After all, even the bottom of the barrel mobile devices moved away from monochrome displays decades ago. But in this case, that’s not what you really want. Since the printer operates on a single wavelength of light, the color filters inside the LCD are actually absorbing light that could otherwise be curing the resin. So an MSLA printer with a monochrome screen would use less energy and print faster. There’s only one problem: it’s not very easy to find high-resolution monochrome displays in the year 2020.

Long story short, manually creating monochrome displays for low-cost MSLA printers might not be a viable option. Until a better solution comes along, you might be interested in seeing some slightly less invasive ways of improving your resin print quality.

However, that’s no longer a stumbling block. There are a number of new technologies that have been created, bringing down the cost of 3D printing significantly. One of those is the LCD 3D printer.

We are going to explore what anLCD 3D printer machineis, the parts that make it work, the process itself, the benefits it has brought to the industry, and the challenges people who operate them experience. If you have always had a curiosity about how 3D printing is all about, then you are in the right place.

1986:The first official patent was issued to Charles Hull for the Stereolithography Apparatus (SLA). Funding issues are the reason why Dr. Kodama never got the chance to have it issued in his name earlier.

What followed next was a number of companies like Google investing a lot of money in developing 3D printing further. This not only made them smaller but brought their access closer to the people. Although the technology still has a long way to go, the many contributions that have been added over the years have made it possible for 3D printing to gain so much in a short period of time. It"s only a matter of time before they become the norm in the daily lives of people. Now for less than $300, you can get yourself an LCD 3D printer.

An LCD printer is a type of printer that uses an array of UV LCDs as the source of light. The light emanates from the flat LCD panels and is shined directly in a parallel manner against the surface of the building area. The light is very focused without any expansion, a feature that reduces pixel distortion that is common in many other 3D printing techniques in the market right now.

Due to this, LCD 3D printers are in high demand around the world as their print quality is higher. The higher the LCD density, the more pixels the final output has and the sharper and more realistic it gets.

As earlier mentioned, the technology behind 3D Printing has become cheaper by the day, and now you can have your own 3D printer in your house. But to safely operate the machine, you have to understand how it works in the first place. The following are the steps that an LCD 3D Printer uses to create an object from scratch.

Step 2:The UV-sensitiveliquid polymeris then hit with a computer-controlled UV laser to change the resin into a solid-state from the aqueous solution. In layman’s terms, this is the point where the laser draws the outlines of whatever you are trying to print onto the resin layer, hardening the needed parts only with every touch. The parts that are not needed will not be touched by the laser, and they maintain their liquid state.

3D printing technology has transformed human lives in ways that cannot be described, and the more advanced and cheaper they become, the more their applications and benefits they bring. The following are some of the notable benefits of using an LCD 3D printer.

3D printing is slated to bring down the cost of manufacturing once it goes into mass production. There are no tools involved in 3D printing, all you require is a computer, a modeling program, and the printer itself, and you are set. This will reduce lead times, the costs of getting tools, and the labor costs of having to operate those tools. The ability to make complex objects without any use of other tools is going to transform the manufacturing industry in a very significant way in the near future. You only need someaccessories and add-onsto make the process easier.

The best part of 3D printing is that finally, manufacturing can be controlled based on need and demand rather than manufacturing in anticipation of demand which leads to surplus and waster of energy. This will eliminate huge inventories, the need to hire storage as well as cut down on the costs of transportation.

3D printing is becoming faster by the day, and when you consider that it involves creating something from scratch using rudimentary raw materials, the sheer brilliance behind the technology starts making sense. One of the manufacturing processes that has benefited greatly from these increased speeds is theprototyping segment, where different parts of the same items can be made at the same time in concurrent processes and later joined up, cutting down the time needed to create products. Once this goes full scale, we will experience manufacturing speeds never seen before.

A goodLCD 3D printerwill save you a lot of money and headache. There are currently a good number of models and brands in the market, each claiming to be better than the next. Making the selection can therefore be a little confusing if you don"t know what it is you are looking for exactly. The following are some of the factors you have to keep in mind when choosing a quality LCD 3D printer.

The Software:There are two types of software you have to deal with. The first one is the modeling software that you use to design the products you want to print. It has to have all the tools, and it must be compatible with the printer. The second software is the one that runs the printer. It should be ‘open source,’ meaning it has to be customizable, allowing the user to set it in line with their needs.

LCD display:A primer that allows you to operate without the need for a computer nearby is more convenient. Having an LCD display withcontroller boardsmakes your work easier as you have fewer buttons to deal with. It also reduces the complications associated with setting up a computer nearby.

Durability and ease of maintenance:As much as their prices have come down considerably, there’s no reason why you should have to be subjected to breakdowns and the need for maintenance after every use. Go for a 3D printer that is durable and can run for long without any maintenance. Having totroubleshoot problemsevery few days will disrupt the quality and speed of your work.

Current trends and the space of development point to a future where 3D printers will be so widespread that people will own them in their houses the same way they own electronics. This will change consumption patterns for people as they will have the power to create most of what they need, and that is a good thing.

Advancements in 3D printing, along with product complexity and different types of available processes have made it challenging to select the right 3D printer for high-volume manufacturing. Digital Light Processing (DLP) and LCD are two commonly implemented resin-based 3D printing technologies. The following compares DLP vs. LCD 3D printers, their unique features, and the subtle differences.

Resin-based 3D printing technologies (also known as vat-polymerization) such as stereolithography or SLA, DLP, and LCD involve curing a photosensitive resin using a light source that helps solidify the resin and create the printed product layer-by-layer. The post-processing steps include cleaning the excess uncured resin and exposure to UV light for final curing. However, the major difference lies in using different light sources for curing the resin.

Next-generation DLP and LCD 3D printing platforms built on LuxCreo’s LEAP™platform are delivering new capabilities that simplify manufacturing and enable high-volume production. LuxCreo’s LEAP™platform outperforms current DLP, LCD, and SLA printers by developing and tuning software, hardware, and resin to deliver new capabilities: high throughput, maximum batch size, and DigitalPolishing™.

DigitalPolishing™ eliminates 90% of the post-processing polishing labor allowing manufacturers to print clear, transparent parts with no polishing required, eliminating the Achilles heel of SLA, DLP, and LCD vat-polymerization systems.

Applications:With DLP printers, the number of pixels does not change and remains the same regardless of the size of the image. Therefore the precision of printing is impacted depending on the size of the model. The narrower the size of the model, the higher the precision. That is why DLP 3D printers work best for accurate and precise printing of small-sized models with details as fine as .05 mm and are widely used for 3D printing of dental implants, jewelry, footwear, and others.

Speed:The higher intensity of light facilitates faster printing. By utilizing a wavelength of 405 nm with light intensity as high as 20-30 mW/cm2, DLP 3D printers can cure an entire layer at once and require less time to print more parts in a batch. Lower DLP wavelengths, including 385nm, are used to improve clear part accuracy and open up other traditional SLA resins for use on DLP. However, there are advantages and disadvantages to selecting 405nm or 385nm depending on if speed, precision, and/or longevity are the priority.

Pricing:DLP 3D printers traditionally are higher-priced printers vs. LCD printers. For this higher price, industrial Smart Factory DLP 3D printers are designed for volume manufacturing with consistent batch-to-batch and machine-to-machine production. Smart Factory DLP 3D printers provide higher speed, larger build volumes, longer life, and higher precision across large build areas versus LCD printers.

How it works:Unlike a DLP printer which is used as a projector, an LCD printer does not use a projector and deploys an array of UV LEDs as the light source and an LCD to mask (block) UV light allowing only select areas to be cured in the layer. Inexpensive LCD printers utilize cheap light sources that have low uniformity and produce light that is not columnated (aligned with the print area). This results in pixel distortion. LCDs also have a much shorter life versus DLP light engines requiring owners to frequently replace LCD screens, increasing consumable cost versus DLP printers.

Print Quality:Higher quality LCD can produce high-quality prints; however, as LCDs become larger, they have limits on uniformity, and batch to batch, machine to machine variability becomes an issue. Less expensive LCD 3D printers have challenges controlling distortion caused by a lack of LED array uniformity and alignment. If these technical challenges are not addressed, the print quality can be and be worse than in DLP printers.

Applications:Compared to FDM 3D printers, LCD printers offer better printing quality for the same price and are therefore popular for chairside dental or desktop applications. The lower cost barrier makes these printers popular for adopting 3D printing across dental, jewelry, engineering, hobbyists, and other industries.

Speed:Compared to DLP 3D printers, LCD printers are slower and are low in intensity in the range of 3-5 mW/cm2. Conventional LCD 3D printers can not print with high viscosity.

Pricing: LCD printers are created as an affordable alternative to their advanced 3D printing counterparts. With an easily replaceable LCD panel, these printers are customized for small spaces and are desktop-sized for ease of use.

When deciding between DLP vs. LCD 3D printers, a popular perception is that the DLP printers are better than the LCD. However, on a budget, next-generation LCD 3D printers can be the right first step into resin 3D printing, depending on the application-specific applications.
