prusa mk2 lcd panel made in china

The Prusa i3 MK2 is an excellent 3D printer for people who want to start with 3D printing. It is most suited towards beginners as it is very user-friendly, but at the same time offers some advanced features as well. All in all, the Prusa i3 MK2 is an excellent choice for anyone looking to get into 3D printing. Yes, it has a higher upfront cost than some other 3D printers, but the time it will save you during setup and before printing is incalculable. Plus, with such a vast array of supported materials, you have unlimited potential for growth.

Today, we’re going to review a 3D printer that’s often imitated yet never surpassed. We’re talking, of course, about the Prusa i3 MK2. Now, before we begin, you should be aware that Prusa’s website is the only legitimate vendor of this product so don’t buy it from any other marketplace.

Simply, the i3 MK2 takes the hassle out of setting up a print. It comes with a heated bed and cold corner compensation, but what does this mean? Basically, filament tends to stick to cold surfaces and this feature ensures the bed remains at a constant temperature all over. That’s not bad, but there’s more.

The Prusa i3 MK2 features a built-in LCD display and SD card, controller. An 8GB SD card is also included to get you started but if you’re a heavy user, you’ll likely want to upgrade this in the future. It also uses cutting edge modern technology to stay as quiet as possible during the printing process – usually around 50dB, which is comparable to the noise from moderate rainfall.

The MK2 can print with the usual suspects: PLA, ABS, and PET, but also supports HIPS, Flex PP, Ninjaflex, Laywood, Laybrick, nylon, Bamboofill, Bronzefill, ASA, T-Glase, carbon fiber, and polycarbonate filaments. That’s outstandingly versatile, even for a printer of this price. A single 2lb spool of silver PLA is included so you can get started as soon as possible.

We’ve all seen them: instructions that look like they’ve been translated into Chinese and back. They’re almost useless and unfortunately, all too common. In contrast, Prusa provides a thick instruction booklet with illustrated, concise directions on how to set up and configure your new 3D printer.

All in all, the Prusa i3 MK2 is an excellent choice for anyone looking to get into 3D printing. Yes, it has a higher upfront cost than some other 3D printers, but the time it will save you during setup and before printing is incalculable. Plus, with such a vast array of supported materials, you have unlimited potential for growth.

USE THESE INFORMATION AT YOUR OWN RISK. I am not responsible for any damage done to your printer or LCD when using these information. I hope you find them useful, I try to make them as accurate as possible but they may contain mistakes.

The LCD Touch Screen is build around an ARM kernel and simplifies the development of user interfaces: the different screens are defined by a set of files (images, fonts, etc) stored in the flash memory of the panel and they can be customized using a graphical editor (part of DGUS SDK).

A set of resources, made by the manufacturer of the 3D printer (Wanhao, Monoprice, Coccon) or yourself. This component is often called "LCD firmware" even if it is wrong.

The last point is very important. The LCD (i.e. DGUS) is not able to handle other formats like top-down bitmaps. To convert images to the right format, you can use ImageMagick convert:

IMPORTANT: You have to use a microSD card with a maximum capacity of 8GiB. If you use a microSD card with a greater capacity, the results are unreliable (sometimes it flashes, sometimes not). This is a limitation of the LCD display itself.

Most of the changes (such as for the second serial line or the Mini LCD) have nothing to do with the Wanhao i3 Plus, but deal with MakerLab Maker printer.

He has printed through dozens of rolls of filament, has owned multiple printers, and has designed custom 3D-printable models for home improvement, product testing, and cosplay. His current personal printers are the Prusa i3 MK3S+ and the Elegoo Mars 3.

Be warned that no 3D printer is unbreakable. A day will come when you’ll need to replace a part or get your hands dirty in some other way. Replacement parts are available for the Prusa Mini+ and MK3S+, but not all 3D printers are equally easy to fix. You might want to avoid 3D printing altogether if you aren’t confident that you’d be able to perform a minor repair on the equivalent of a household appliance.

We also note how many times we have to repair the printers, how often each machine needs its print bed leveled, and how difficult it is to remove completed models from the print bed. These are general issues that pop up for any tier of 3D printer, but some printers are better than others at reducing the time you have to spend cleaning and repairing them.Our pick: Prusa Mini+

The Prusa Mini+ offers the best overall 3D-printing experience thanks to its combination of print quality, reliability, and desk-appropriate size, all offered at a relatively low price. It produced some of the best-looking prints among the machines we tested, it works with a wide variety of filament brands and types, and it comes preassembled. (You can save some dough and buy a kit to assemble the Mini+ yourself instead, though we didn’t test kits because of the added skill involved.) Prusa printers are the quietest we’ve tested, which makes them especially bearable to work alongside in an office.

We decided to use the free PrusaSlicer software program to prepare files for printing. We still prefer the detail packed into Ultimaker Cura, another free program compatible with a wide range of printer types, but we found PrusaSlicer easy to use and reliable in how it prepared files for the Mini+. It has plenty of customization options for the average 3D-printer owner.

We used a USB stick to transfer files from our computer to the printer, but Prusa has published a guide to a DIY upgrade that allows you to send files over Wi-Fi. Once you plug in the USB stick, you can use a knob to scroll through the menu and file list on the Mini+’s color screen, which we found to be much easier to parse than the blue and white, text-only screen of the Prusa i3 MK3S+.

Although the MK3S+ has a larger, 9.9-by-8.3-by-8.3-inch PEI print bed, the Mini+ is no slouch with its 7-by-7-by-7-inch print volume. (For an even larger print bed, check out our also-great pick, the Artillery Sidewinder X2.) Most free models you’ll find available on library websites like Thingiverse are made for this size of print bed, so it’s not often that you’ll max out its abilities. We were able to remove the bed and bend it to pop off prints, but usually we used a scraper and gentle pressure instead. The Mini+ isn’t flashy, but it’s especially practical. It automates as many quality checks as possible, so there’s less manual setup each time you print. It’s also built out of replaceable parts; that’s useful if you plan to run the printer continuously and want it to have as long a lifespan as possible. And Prusa’s printers are upgradable, whether you want to add nicer parts or swap in features from the latest printer.

The Mini+ can print in standard plastics such as PLA and ABS, plus materials like nylon and wood blends. If you’re interested in even more exotic materials, the MK3S+ is a better choice. Prusa makes a line of reasonably priced filament in many types of materials that we have enjoyed using, but the Mini+ is compatible with filaments from other brands, too. We have used Hatchbox filaments with good results in other printers in the past, but we haven’t tested them on the Mini+.

Spending more on a 3D printer gets you, well, more: Touchscreen controls and the ability to print over Wi-Fi are two features we’ve enjoyed on more expensive printers. One benefit of using a USB stick instead of Wi-Fi is that you can save multiple prints to the stick at once; that way, when the first job finishes, you can remove the print and start the next one without having to go back to your computer. But we look forward to Prusa’s addition of Wi-Fi abilities in the future.

The Mini+ has a totally open design, which means that it releases the VOCs and particulates that it produces while using certain types of filament like ABS. You might notice a maple-syrup or plastic smell from the melting filament. If you’ll be using the machine in a home environment, it’s a good idea to use a “healthier” plastic such as PLA. It’s also a good idea to print at the lowest temperature possible for your chosen material; the lower the temperature, the less bad stuff the printer releases into the air. If you plan to spend time in the same room as a running 3D printer and don’t have a ventilated hood or HEPA air filter, turn on a fan or crack a window to improve ventilation (PDF). It’s also a good idea to wear gloves to prevent skin transfer.Upgrade pick: Prusa i3 MK3S+

The Prusa i3 MK3S+ offers the reliability and print quality of the Mini+ along with a larger print bed, a more stable design for greater printing detail, and a better extruder that can handle a wide array of materials. It also comes preassembled or in a DIY kit, though we found the preassembled kit much simpler to set up than the Mini+.

Several software options are available for the MK3S+; we used Cura, downloaded directly from the Ultimaker website. Cura is compatible with a wide range of printers, so during setup you should pick the MK3S+ profile to ensure that the software is tailored to your machine. We’ve used Cura for years without issue. Beginners can start a print quickly, without much thought, or drill deeper into the settings in the software’s intuitive menus when they’re ready to do more fine-tuning. It’s also worth checking out PrusaSlicer, which, as the name implies, is Prusa’s version of slicing software; there, the company offers expertly tuned profiles for its printers and filaments, as well as helpful features like variable layer height based on where your model has the most detail. It also has great features for generating custom support material, which is like scaffolding around your print that helps your printer lay down material at gravity-defying angles. In PrusaSlicer you can “paint” the areas on your model where you want support material, and the slicer will build that scaffolding up from the build plate to meet those specific areas, making the print less prone to failure.

You can print on the MK3S+ over Wi-Fi directly from PrusaSlicer if you install a Raspberry Pi Zero W into your machine, or you can save your file to an SD card and insert it into the machine. Using a knob, you can scroll through the black-and-white menu on the MK3S+’s small screen to select which model you want to print. It isn’t the flashiest or most intuitive system, but it is similar to what you’ll find on most other $1,000 printers.

If you aren’t sure you want to commit to using a 3D printer regularly, or if you just want to spend a bit less, the Monoprice MP Cadet is a good budget option. In our testing, this $200 printer made prints that looked just as good as the results from printers that cost several times more, and its small size makes it especially desk friendly. Its removable, unheated bed is also more suitable for little fingers and releases finished prints with ease (though it puts your prints at risk of warping). However, this machine lacks the relatively advanced features you get from more expensive printers such as the Prusa Mini+ and i3 MK3S+.

The MP Cadet is noticeably smaller than most printers, with an overall footprint of just 8.3 by 8.3 inches. However, because its print bed is not enclosed and it doesn’t have a heated bed, you need to keep it away from open windows and in an area with a relatively constant temperature so that the air doesn’t warp prints. The work area should also have good airflow, such as a small fan nearby. The melting filament gives off a maple-syrup or plastic smell, so in addition to having airflow in the room, you should avoid sitting right next to the printer as it operates to avoid inhaling the fumes. The MP Cadet is noisier than the Prusa i3 MK3S+, too, though it isn’t unbearably loud.Also great: Artillery Sidewinder X2

However, this printer is best for people who know they want to print a lot of large objects. It’s physically very large and would commandeer the kind of desk found in a bedroom or a small office. The Prusa models are even easier to set up and maintain, have much better support communities, and are more repairable.Care and maintenance

If your printer doesn’t automatically level its print bed, periodically check the print bed and adjust it if necessary. The Monoprice MP Cadet is self-leveling, while the Prusa Mini+ and MK3S+ have a calibration option (called the Wizard) in their menus. Most of the time, if your print isn’t sticking to the bed or is otherwise failing, it’s because the bed isn’t correctly leveled.

So why don’t we recommend it as a top pick or even a budget pick? In our experience, we’ve found that the Ender-3 line requires more setup and more maintenance, and in comparison with our picks it poses a much more difficult learning curve for those who are just getting into 3D printing. As an example, crucial tasks like leveling the print bed on the Ender-3 require using separate calibration files that might have to be run multiple times or manually moving the print head across the bed, in contrast to Prusa’s and Monoprice’s easier, more automatic workflows. This manual work adds many minutes of pre-print setup for a 3D-printing newcomer versus seconds for our top picks, and in turn it leads to a higher chance of the machine sitting in the corner gathering dust. These processes become rote after time and are made easier by optional upgrades, but initially they require some dedication to learn.

Prusa models also earned the top-pick and upgrade-pick spots due to the company’s excellent support and fantastic forum filled with helpful printer owners. Ender-3 owners are more likely to find someone with the same problem, but owners of Prusa models are more likely to find a solution.

The Creality Ender-2 Pro, a $170 competitor to the Prusa Mini+, seems built to look nearly identical to that model. However, in our tests its menus were confusing and made the printer more difficult to operate than any of our picks. Its fans were also drastically louder than those of any other printer we tested.

In some ways, the Dremel DigiLab 3D40 impressed us: For about 50% more than you typically pay for the Prusa i3 MK3S+, you get an enclosed print area, a huge print bed (though not quite as large as that of the MK3S+), a touchscreen, and cloud-based printing. However, its prints in our tests didn’t look quite as nice as those of the MK3S+. We also found removing prints to be difficult, and we managed to ruin two flexible beds when the top layer ripped off during print removal. Finally, we dislike that the 3D40 prints only with proprietary spools of PLA—if you want to use other types of Dremel filament, you have to spend several hundred dollars more on the Dremel DigiLab 3D45.
