why does lcd module need sla price

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.

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

You"ve probably heard of LCD, SLA and DLP 3D printers - but what"s not clear: which one is most suitable for your dental office or lab? And which specs matter? We’re here to help you out.

SLA, LCD, and DLP are the most commonly used 3D printing technologies in the dental industry. All three use photosensitive resins, which means that layer by layer is cured using a light source. This process transforms liquid resins into solid layers and, eventually, whole parts. This makes it sound like the 3 technologies are the same – but they’re not.

SLA was the first 3D printing technology produced. Since it was first developed in the 1980s, not much has changed. Unlike DLP and LCD technologies, the light source used is a laser. The laser beam sweeps across the resin tank and solidifies the material layer by layer.

In 3D printing, DLP does not use a laser, but a projector. The moment the light hits the resin, it’s not restricted to a single spot as with SLA. Instead, the whole layer is formed at once. Here, patterning of the illumination is critical to achieving the desired shape for each layer.

LCD 3D printing is very similar to DLP, as it flashes entire layers at once curing resin inside the resin tank. What differentiates the two technologies is thelight source.

LCD technology does not employ a projector, but an array of LEDs exposing the UV light through an LCD screen. The screen only lets the light pass through areas that are to be cured, simplifying the process and removing the need for any moving parts.

The resolution has only a very minimal impact on the accuracy of the print. Its major role in 3D printing is the smoothness of the application’s surface. High-end SLA printers will produce parts that are smooth as silk. LCD printers coming in a close second. Comparably, DLP printers produce less smooth results and thus, are not ideal for dental applications such as temporary crowns or dentures.

Determining the right amount of time to commit to for SLAs is a balancing act. As much as we might want to promise instant responses, it’s not a practical promise to make to customers. If we over-promise on response times and don’t deliver, customers will be disappointed and there might be serious contractual consequences such as fines, usage credits, or early contract termination.

On the other hand, SLAs should help the customer feel assured that they will get timely responses if and when they need assistance. Set the goal post too far away and customers will be disappointed with slow responses. Instead, find a balance between over-promising but still meeting the needs of customers - often by personalizing SLA policies by customer segment. Here are six things to think about when designing your SLA team policies.

SLAs are promises you make to your customers. If you’re a smaller company that doesn’t offer contracts or legally binding SLAs, your SLAs might be similar to the internal goals your customer support team sets for response and resolution times.

However, if you’ve outlined your SLAs in your terms of service or in a legal contract, there are serious repercussions for breaches. Your customer support team"s goals shouldn’t be to meet the bare minimum level of service. In this case, you’d want to set your internal team benchmarks more ambitiously than simply avoiding SLA breaches.

Plus, setting your external SLAs the same as your internal goals don’t give you much room for error. Ideally, you should aim to resolve inquiries well within SLAs. SLAs should be the longest acceptable time for a customer to wait, but they shouldn’t be your measurement for quality.

The best practice is to set your customer support team response and resolution goals well below your SLAs so that you’re consistently working to exceed customer expectations.

When determining your SLA policy, it’s important to consider if all customers fall into the same bucket, or if some customers require unique policies. Understanding your customers’ needs based on their plan type or contract requirements and setting up different SLAs can help provide more personalized experiences.

Tiering customers by plan type:High-value customers might get priority over a lower or free pricing plan. While it doesn’t always make sense to set an SLA for free users, setting SLAs for enterprise customers is expected and often required in contract negotiations.

Personalizing SLAs for VIP customers: High-value contracts will often require personalized SLA conditions. With multiple SLA policies, you can set a unique deadline for each customer and for each situation you might encounter.

While every customer concern is important, not all of them are equally urgent. By categorizing common support problems by priority and setting separate SLAs for each type of question, your team can better prioritize the needs of your customers. For example, an outage SLA time might be a lot shorter than a request to update a billing address. Using multiple SLA policies allows your team to get as granular as you’d like to serve each type of customer uniquely.

When setting SLA policies, take customer feedback into account. If customers complain about slow responses or leave negative customer satisfaction responses, it’s time to revisit your SLAs to ensure you’re meeting the needs of all your customers.

Understanding why customers need specific response times is important too. Critical software or products like banking apps or point-of-sale systems might require faster SLAs because any wait time will seem unbearable. Other products, like e-commerce or entertainment apps, might not require as quick of responses - meaning that you can dedicate resources to other priorities.

It might be tempting to optimize SLA policies based on agent availability - but this is the wrong approach to take. Instead, base your SLA policies on the customer experience as a first priority and then staff your team to meet those requirements. If you can’t meet your customer’s expectations and are experiencing SLA breaches, you’ll need to hire more agents to handle incoming inquiries.

Operational Level Agreements are critical to consistently meeting SLAs when there are internal dependencies to resolve an inquiry. As mentioned above, OLAs are agreements between internal teams that help prevent bottlenecks. When an SLA isn’t met, customers don’t care who’s fault it is - engineering, support, or system administrators - they only care that their agreement wasn’t honored. OLAs help teams work together to meet their commitments to the customer.

If you don’t offer support 24 hours a day, 7 days a week, it’s possible to set SLAs that only take into account your operating hours. For example, if you have a 24 hour Response Time SLA, but only have agents working during the weekdays, customers who send in an email Friday afternoon shouldn’t expect a response until Monday. Setting your SLAs to Business Hours instead of Calendar Hours will only keep the timer running while agents are scheduled to be working.

However, while using business hours might make your reporting look better, customers are still waiting over the entire weekend (or night) for a response. They might not care that you don’t have agents working - they only know that they aren’t getting help. If you choose to only report on business hour SLAs, it’s still important to keep in mind the customer experience for customers that live in different time zones or are trying to contact you after-hours.

When I try to create an SLA Contract, I do not encounter errors but the gross and net prices are not displayed in the transaction. There is also no entry in the conditions tab.

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.

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.

LCDs, along with OLED displays, are manufactured in cleanrooms using large sheets of glass whose size has increased over time. You can check Wiki here

Most 5.5inch and 6inch screens are from GEN 4/4.5 include current Sharp04 and the 6inch monochrome screen. You can also find most LCD screens over the world from this website：https://www.panelook.com/

These manufacturers are focus on the bigger generation with OLED, You can find high-resolution screen use on VR/AR products, which is not used on our printer now, our screen is TFT-LCD.

Below is BOE’s generation with the screen type,  the large size LCD mainly uses on TVs, Monitors, Laptops,  and mobiles. But I do believe there will be more option for 3d printers in the soon future.

As shown in below. The aperture ratio of TFT-LCD is about 50 ∼ 80%. Generally, the larger the aperture ratio, the higher the optical utilization rate of the liquid crystal display, and the higher the brightness of the display.

Optical performance includes three main indicators: polarization, transmittance, and hue. The higher the degree of polarization and transmittance, the higher the display efficiency of the LCD display device and the lower the energy consumption.

This actually talks about decrease exposure time, because the UV transmission can reach 6% on a monochrome screen, and RGB LCD is about 1%. Below you can see ELEGOO Saturn is much faster than Mars.

The UV light source also needs an upgrade to work with monochrome LCD. It requests more vertical & parallel light to make sure the quality.There will come out the new UV LED for the mono screen soon and CBD-Tech will keep an update.

Many companies are preparing their 2K mono printers this year, the customer who owns Phrozen sonic mini has already experienced a Monochrome LCD printer.

If you are interested in upgrade your RGB screen to monochrome LCD, Take a look at ChiTu systems online store, and we also the original RGB color screens for mars and photon.

So far, photocurable 3D printing has been difficult to be used in humans directly due to the low biocompatibility of photosensitive resin. Now, materials that can directly contact with human body through photocuring 3D printing are mainly inorganic materials. Bone materials with biological activities, such as hydroxyapatite and biological glass, are not photosensitive materials and need to be mixed with photosensitive resin. Therefore, the biological activity of products will be greatly affected after printing. Generally, after photocuring 3D printing, the material is dealt with sintering to remove the resin, leaving only the inorganic part, which is expected to be used as a substitute material for bones, teeth, etc. However, the volume shrinkage caused by the removal of organic matter needs to be compensated by software compensation technology, while the data calculation of special-shaped materials is very large, this software technical is not mature enough at present. At the same time, due to a large number of inorganic material filling, the resin is like paste and could not flow. Therefore, the photocurable 3D printing equipment for printing inorganic materials is unique. None of the printing devices described above can be implemented. More biomedical photocurable 3D printing materials are still in the academic research stage, involving scaffold printing, hydrogel printing and cell printing. Cui et al. [25] used PEG-DMA/chondrocyte mixture solution as bio-ink to print cartilage defect sites under ultraviolet light. The result showed the cell survival rate was relatively high. However, in the process of photocurable printing, several factors, such as the photopolymerization reaction, different wavelength, laser power, exposure time and photoinitiator, affect the cell activity inevitably [26], to some extent, limited the application of this print mode.

Some research groups prepared degradable biomedical support through photocurable 3D printing. It is known that polycaprolactone (PCLS), poly (lactic acid) (PLA), and medical polyurethane (PU), which is synthetic material, has been proved of good biodegradability and biocompatibility, and is widely used in the field of tissue engineering. Petrochenko et al. [27] used the photosensitive resin which was composed of polyurethane diacrylate (UDA) resin (Genomer 4215), two photosensitive diluents, 2-hydroxy-ethyl acrylate and glycol diacrylate to print support by SLA 3D printing technology, the printed sample was washed by 70% ethanol and 30% acetone solution repeatedly to remove the unpolymerized resin and diluent. Thus, the honeycomb scaffold with a porosity of up to 60% was obtained, mesenchymal stem cells (MSCs) were seeded on the surface of this honeycomb scaffold, it was found that the cells could be distributed on the porous scaffold evenly with a high adhesion rate, the pseudopodia of the cells were closely attached to the surface of the scaffold. With the regeneration of tissues or organs, the biodegradable scaffolds begin to degrade gradually, when the new tissue is fully grown, the scaffolds also completely degrade. Danilevicius et al. [28] successfully prepared tissue engineering scaffolds with three-dimensional porosity using PLA materials though SLA printing technology. They investigated the effects of porosity of scaffolds on physiological characteristics such as cell growth, adhesion and reproduction, the results showed that 3D printing technology can control arbitrary voids and porosity during the preparation of PLA tissue engineering scaffold model.

In the practical application, most of the photocuring 3D printing materials do not contact with the human body directly, such as in the field of dental restoration, dental orthodontic, dental surgery and so on. While, the application in biomedical field is mainly in the academic research stage [29,30]. Custom-made capacity and high precision of the photocuring 3D printing technique entitles this technique quite meet to fabricate the tissue engineering material. However, confined by the limited biocompatibility of photosensitive resin, it is difficult to employ the photocuring 3D printing technique in the biomedical field at present. It requires the innovation and mutual collaboration of both printing technique and material. For example, commonly, in the present, the hydrogel is printed by the injection printing for the low strength of the hydrogel. The printed hydrogel is of low precision and rough surface. Some tough hydrogels have been developed; however, it requires high intensity and short wavelength of light. Meanwhile, to print the hydrogel, the printing space of 3D printing machine should be kept constant temperature and humidity to prevent moisture volatilization. Brief summary, photocuring 3D printing has a promising future in biomaterials, but it still needs to overcome the difficulties in technology and materials.
