About us

Hello, we are Prusa Research!

And we make more than just amazing 3D printers!


Prusa Research was founded as a one-man startup in 2012 by Josef Prusa, a Czech hobbyist, maker and inventor - and now one of the most famous names in the 3D printing industry.

Josef found his passion for 3D printers as a student of University of Economics in Prague. That was in 2009. Back then, he considered 3D printing to be nothing but a hobby, an amazing new technology open to changes and improvements. Josef then joined the open-source RepRap project and the rest is history.

It's pretty cool history, actually! Scroll down and see how Prusa Research was born and how we reached the top of the global charts!



We started really small. There were no investors, no Kickstarter campaigns. Just a man with a plan (and a huge stack of pizza boxes, which were used to ship 3D printer parts from a small basement workshop to the whole world). The beginnings were modest, but pretty exciting! 

As time went by, the Prusa i3 design became one of the most popular FDM 3D printer designs adopted by many manufacturers and hobbyists across the world thanks to its open-source nature.

And now? Now, there are more than 700+ people working in Prusa Research and we ship over 9000 printers worldwide directly from our HQ in Prague every month! We have become the no.1 fastest growing tech company in Central Europe (Deloitte 2018) with a growth rate of 17118 % over the last four years and claimed the no.1 spot in Deloitte's 2019 BIG 5 category with the growth rate of 4527 %!

But despite all these numbers, visiting Prusa Research is like visiting a craftsman's workshop - a workshop sprawling across eight floors of a huge old Prague factory! We develop our own hardware and software, invent, improve, tinker, experiment and do all sorts of awesome stuff.

And we are staying faithful to our roots. Our award-winning Original Prusa i3 3D printers are still open-source and plenty of their parts are printed by other 3D printers - that’s why we also have “The Farm”, a large hall with more than 600 printers that create parts for other printers!



    The Road to 100,000 3D printers


    Watch the documentary describing Josef's journey - from a small basement workshop to founding a globally recognized brand and a massive factory that ships thousands of 3D printers to the entire world every month.



    Open-source technology and why it matters

    We wouldn’t exist without open-source. Prusa i3 3D printers were born from the idea of an open-source machine and we are still faithful to this ideology. Everything we do, everything we sell, is open-source. What does this mean? All source codes, printed parts, blueprints, circuit board designs… everything is freely available to anyone via GitHub. Because we strongly believe in the community and in sharing knowledge.

    Products and Projects



    Original Prusa MK4

    Reliable and easy to use high-speed 3D printer

    Original Prusa MK4 is the successor to our award-winning Original Prusa i3 MK3S+. It has all the best features of the popular MK3 – an open-source 3D printing workhorse with easy maintenance and advanced safety features – and adds much more!

    The MK4 will consistently deliver a perfect smooth first layer thanks to the Loadcell sensor (no manual adjustments needed). The next-gen extruder (Nextruder) and 32-bit connected platform provide many quality-of-life improvements like remote printing, quick-swap nozzles, and customizable UI with a one-click printing option. It also supports high-speed printing with Input Shaper and Pressure Advance. And it’s still beautifully quiet. Network features include Prusa Connect, which allows to remotely control your printer from anywhere in the world!

    The functionality of the MK4 can be further expanded with our unique Multi-Material Upgrade 3 addon for printing with up to 5 materials simultaneously.

    The MK4 is available both assembled and as an assembly kit.

    Original Prusa MINI+

    Smart and compact 3D printer for everyone

    The Original Prusa MINI+ is our new compact 3D printer with all the bells and whistles you would expect from the creators of the award-winning Original Prusa i3 MK2 and MK3S+!

    The MINI+ is a big printer in a compact body. We did our best to squeeze as many features into the lowest possible price as possible.

    The MINI+ is great for beginners, companies looking to build a printing farm and 3D printing enthusiasts worldwide.

    Original Prusa XL

    Large-scale CoreXY 3D printer

    The Original Prusa XL is a large-scale CoreXY 3D printer with a build volume of 36×36×36 cm (14.17’’×14.17’’×14.17’’). Featuring an optional tool changer with up to 5 independent tool heads, automatic first layer calibration for an always-perfect first layer, and many smart features.

    The XL comes with the brand new “Nextruder”, a completely redesigned extruder with a planetary gearbox, hot-swappable nozzles and a Load Cell-based system for fully automatic first layer calibration. The print quality is further enhanced by the XL’s modular bed design - instead of using a single large heatbed, which is prone to warping, the XL uses an array of smaller, individually-controlled segments. Only the necessary part of the heatbed is activated when printing smaller objects, making the XL energy-efficient. The XL can be easily expanded up to five tool heads thanks to a highly accurate tool changer with automatic calibration via the load cell sensor. Our internally developed kinematic coupler mechanism ensures millions of trouble-free tool changes. The tool heads are available individually in our e-shop as optional upgrades.

    Original Prusa SL1S SPEED

    Fastest MSLA 3D Printer

    The Original Prusa SL1 was our first foray into the world of SLA printers. We wanted to build a solid, sturdy and robust 3D printer that would produce consistent, high-quality 3D prints. Based on the general feedback and reviews, we did many things right. The SL1 found its way not just into hobbyists’ workshops but into various industries as well.

    The vastly improved version of the SL1 is finally here! Called SL1S SPEED, it features a brand new high-resolution monochrome LCD and high-performance optics, a larger print platform, and all cumulative updates from the entire lifespan of the SL1. The new SL1S SPEED is a lightning-fast machine that requires just 1.6 seconds per single to produce amazingly detailed 3D prints.

      Our print farm


      See how hundreds of 3D printers produce parts for new printers!

      A 3D printer that can print most of the parts for a whole new printer, that was the idea behind the RepRap project, from which the Prusa i3 was born. But, the more printers you want to print, the more printers you need. Right now, we are running almost 600 3D printers on our farm and, as far as we know, it is the largest 3D printing farm in the world.

      We use 2 kg spools to decrease the frequency of filament spool changes. Each printer can print a whole set of plastic parts for MK3S+ in 27 hours. Furthermore, the farm consumes about 6 tons of filament every month.


      When you take a look at our huge 3D printing farm you might ask yourself, “Wouldn’t it be better to just use injection molding?” Well, in some cases, it might. Even though a single mold can cost tens of thousands of dollars, it could be more effective. However, using 3D printing gives us one huge advantage – thanks to 24/7 heavy load we can keep innovating and upgrading our printers as we have to resolve every found issue. And in that case, injection molding is no longer a better solution. A 3D printer can also create much more complex parts than injection molding. And our workflow is also way simpler. As soon as we come up with a part improvement, we just test it, upload new gcode to the print farm and within hours we start shipping improved printers to our customers. Basically, we are leveraging one of the biggest advantages of 3D printing to the maximum.
