INTRODUCING THE ORIGINAL PRUSA I3 MK3S+ 3D PRINTER!

The Original Prusa i3 MK3S+ is the latest version of our award-winning 3D printers. We have upgraded the MK3S with a brand new SuperPINDA probe for improved first layer calibration, added high-quality Misumi bearings and various useful design tweaks to make the printer easier to assemble and maintain. The MK3S+ includes all the proven features of the previous models, including the heatbed with removable PEI spring steel print sheets, automatic Mesh Bed Leveling, filament sensor, power loss recovery (power panic) and safety features. And it is still as silent as ever!

The MK3S+ is available as an assembly kit, which is the best way to get to know your new 3D printer. Assemble it screw by screw to learn truly everything about its design and how it works! You can also get it fully assembled and factory tested, so all you need to do is to unpack it and plug it in.

Thanks to all of these (and many other) features, the MK3S became the “Best 3D Printer” according to ALL3DP. The MK3S is also the highest-rated 3D printer, and the “Editor’s Choice”, in the prestigious MAKE:MAGAZINE’s Digital Fabrication Guide 2019. The MK3S is also featured in TechRadar's Best 3D printers of 2021 as The best all-around 3D printer. NY Times wrote that "...of the 11 printers we’ve tested over the past five years, the Prusa i3 MK3S printer has produced the largest and best-looking prints." According to ZDNet, the MK3S is "The best pro-sumer 3D printer under 1000 USD."

The functionality of the MK3S+ can be further enhanced by our unique Multi-Material Upgrade 2S for printing with up to 5 filaments simultaneously.



Our printers have received many awards over the years and we keep working hard to make them even better!


WHAT’S NEW IN THE MK3S+

SUPERPINDA PROBE

SuperPINDA probe features a hiqh-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the MK3S+ probes the bed in several places and creates a virtual heightmap of the print area. This process ensures that the first layer will always be spot on!

MISUMI BEARINGS & MORE

The MK3S+ features a new set of metal clips for the genuine MISUMI bearings on the Y-axis. The belt tensioning mechanism on the X-axis was reworked and the X-end plastic parts reinforced. The filament path in the extruder was altered for better support of flexible filaments.

DOZENS OF TWEAKS

With all the cumulative upgrades from the entire MK3’s life cycle on board, the MK3S+ is the best version of our award-winning 3D printer so far. Genuine Gates belts, Bondtech drive gears, EINSY RAMBo motherboard, IR filament sensor, and many other features are the reason why the MK3S+ is the perfect 3D printing workhorse.


WHAT WE ARE PROUD OF...

The most significant features of Original Prusa i3 MK3S+

REMOVABLE PRINT SHEETS

Alt Text

Spring steel sheets are easy to maintain and make removing the printed object from the print surface a breeze. We offer three types of print surface: smooth, textured and satin to cover all your needs when printing from a wide range of different materials - most of which do not require any special separation layers or surface preparation.

HIGH-QUALITY PARTS

Alt Text

The MK3S+ features an aluminum extrusion Y-axis assembly. Thanks to the milled dural frame, the MK3S+ is stable, rigid, and easy to assemble. Combined with our internally developed extruder featuring Bondtech gears and the E3D V6 hotend, the MK3S+ can print high-quality objects up to 210 mm in height.

MESH BED LEVELING

Thanks to the SuperPINDA probe, the MK3S+ can use the Mesh Bed Leveling process to compensate for microscopic imperfections of the print sheet, and inconsistencies caused by the assembly and stacking of the manufacturing tolerances of various parts. Achieving a great-looking first layer is quick and easy.

POWER LOSS RECOVERY

Are you afraid of a blackout ruining your 48-hour print? Worry no more - the MK3S+ can deal with that! The printer can fully recover from the loss of power and continue printing exactly where it left off. It detects power interruptions and shuts down the heatbed and extruder heating, and saves the last known location.

FILAMENT SENSOR

The MK3S+ further enhances the reworked extruder from the MK3S. The built-in filament sensor uses a reliable trigger system, which detects whether a strand of filament is inserted into the extruder. It can detect any type and color of filament and is not susceptible to mechanical wear.

SILENT AND FAST

Thanks to the Trinamic 2130 drivers and super silent fan, the MK3S+ supports the stealth printing mode, which makes the printer extremely quiet. Even in the normal printing mode, the MK3S+ is quieter than most 3D printers on the market. In the normal mode, the MK3S+ can achieve a print speed of more than 200 mm/s!

SLICE WITH PRUSASLICER!

Our internally developed multiplatform slicer comes with in-house made and fully tested profiles for all of our 3D printers and a wide range of filaments. With built-in tools, such as advanced support generation, cutting, automated object distribution, ironing and many others, you will turn your 3D models into print files in no time!

SUPPORT FOR PLENTY OF MATERIALS

The MK3S+ is fully compatible with a wide range of various types of materials. No matter whether you want to print something for fun from PLA and flexible materials, or you need to produce durable prototypes from PETG, ASA, Polycarbonate and Polypropylene - the MK3S+ can handle them with ease.

OPEN-SOURCE HARDWARE & FIRMWARE

We develop firmware for all of our 3D printers and test every new version thoroughly before release. Ongoing development and regular updates ensure that our machines are packed with useful features, such as print sheet profiles, automated calibration, Mesh bed leveling, advanced diagnostics, remaining print time estimation, Octoprint support and more!

Kit build was fun and works nice

After app. 6 hours my MK3S+ was ready to fire up. Did not build it at once, some hours here, some there. Great manual, average build but definitely doable if you know on which end a soldering tool gets warm. No, you will not need it, but you should know to handle an allen key.

Finally fired my machine up and get a bit nervous during the X/Y axis calibration. A little bit more (positive) feedback would be nice. But in the end it went fine.

Prints are great, all done with the Prusa slicer. Except the 3Dbenchy from the SD card. The printer kicked it off the bed two times in a row. Every time at roughly the same height. On the textured metal bed. Maybe too less adhesion. Maybe I will try it again on the smooth one. Anyway, don't need a benchy. But the hull looks great. Until the cabin failed.

Rest is fine, no other failed prints, PETG and PLA.

Customer is happy.

    beware of faulty parts and customer service

    2 of provided bearings are faulty, rattle and induce vibrations throughout Y and Z axes, the only advice i got from customer service is "lube the bearings" and "recalibrate z axes with loose trapezoidal nut". Nothing worked. If you are supposed to lube the bearings, why not include the instruction to do so in the assembly manual?

      Great printer!

      I had a Cr-10 for over 2 years before buying the Prusa, but it was more a project than a printer. I probably fixed more than printing. But the Mk3s+ is insane! Its a powerhorse, reliable, I start a print and come back after some hours and it's perfect! It's so good

        Very happy so far

        This is my first 3D printer.
        Building the kit was fun and the instructions are very clear. I would recommend the kit to anyone who has built other mechanical/electronic projects - just take your time and enjoy the build.
        After a couple of goes getting the Z adjustment right it's now printing beautifully - I really am very impressed.

          A great printer that doesn't age well

          I have two 3D printers, this one and a cheap Chinese one, and even if for the first year the experience was incredibly better with the Prusa. But over time it had more & more problem while the cheap one after a few cheap upgrades was completely fine.
          On my Prusa, I had to replace, the bearings, and the X axes rodes. I think the power supply and is getting hotter each day and will need to be replaced soon. All these replacement parts are quite expensive on Prusa compared to the competition.
          Overhaul the Prusa is a good printer but the long term use (and support) are a bit disappointing

          Great learning experience! Awesome customer experience!!!

          Putting together this was fantastic! The guide and added goodies were great! My satisfaction was kicked up to the next level because they not only suggested a reward system for making the printer, but they included the treat!!! Such a simple item to include that really made me think they company cares about their customers.

          Skvělá práce borci od Průši

          Nějakou dobu už jsem tiskl na MK3S+ v práci a rozhodl se si jednu pořídit domů. Objednal jsem stavebnici a netrpělivě čekal na balík...Stavba podle papírového dodaného návodu cca 20h. Návod je přesný a všechno bez sebemenších problémů pasuje, prostě parádička. První zapnutí, test, kalibrace a první výtisk v top kvalitě....Díky Průšaborci.
          Měl bych dvě připomínky...první připomínka: napínáky řemenu Y jsou super inovace, ale chtělo by to aretovací šrouby 2 a 2 a ne 1 a 1, utahování aretovacích šroubků pod řemenem je nešikovné, málo místa...a druhá připomínka: zvětšil bych v návodu instruktážní obrázky zapojení řídící desky. Je to jedna z nejdůležitějších částí stavby a malé jsou méně přehledné.
          Vaše tiskárny mají pověst TOP a já to mohu jen potvrdit, takže ještě jednou...Super práce borci, všude chválím a doporučuji :)

          ..nearly speechless!

          I had seen the reviews, YouTube videos, etc., however, I attributed the reviews to a 'good' product and diehard fan-base.

          I turned to Prusa Research after owning several versions of a competitor’s product. I simply tired of the chore the printers had become for an average print.

          After a straight-forward kit assembly I hopped right into printing. I could not be more surprised and pleased. None of the hassle associated with the other printers – NONE. It simply works, and does a phenomenal job.

          My hesitance at the price is gone, replaced by utter confidence. I am now a believer, and a Prusa Research convert. I just placed another order for my second Prusa Research i3 MK3S+ kit. As soon as I unload the competitor’s products, I’ll be back for even more.

          Thank you!

            wow...

            I have never seen a printer go over a year with 4-5 different transitions of locations just to print perfectly without any required work or calibration to be redone.

            I have easily convinced four other people already to go with PRUSA Mk3s when they asked which brand was the best. With an $800 price tag, the PRUSA blows away nearly all of the competition of printers that costs double what the PRUSA does.

            Won over by QUALITY

            After delivery of the kit, I took my time reading all the material and going online to view assembly suggestions, etc. Time well spent. Though not necessary, the provided instruction book was everything I really needed. A great deal of effort was put into the preparation of this manual. I strongly urge future kit builders to read all the instructions, and NOT be tempted to assemble by picture alone. The manual even states this. Trust me, you will save yourself much frustration by following this advice. After the assembly, and then using the included handbook for configuration and calibration I was pleasantly surprised that the first check of everything was OK. ALL WAS VERIFIED. Happy beyond compare. Did several first layer calibrations and then several sample prints. I can't adequately describe how pleased I was with the results. To any one that wonders if purchasing a Prusa is worth it, YES. Hands down compared to the 4 other knock offs I have purchased, upgraded and tinkered with. None of them even after multiple enhancements can even come close to what my i3 MK3S kit does when properly calibrated and assembled. As other's have stated, I too will be a long term Prusa customer. Thank you for providing a product that lives up to the legend you have created with quality.

            This listing is a DIY KIT for self-assembly. We also offer a fully built and tested 3D printer.

            Warning for US customers: If you select the combination with both steel sheets, your order will exceed $800 (with shipping) and you may be charged with customs duties. More info
