Hello, we are Prusa Research!

And we make amazing 3D printers


We have claimed the number 1 spot in Deloitte's 2019 BIG 5 category thanks to our growth rate of 4527 %!

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. You know, the guy in the photo on the right 🙂

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!

Josef Prusa - The man, the myth, the legend 🙂

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.


Three printer kits sold in five days! Nice! (Jan 2010)

And now? Now, there are more than 600 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 the 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 500 printers (November 2018) that create parts for other printers!

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 i3 MK3S+

Improved version of the award-winning FDM 3D Printer

Original Prusa i3 MK3S+ is the newest version of the MK3, which in turn is the successor to Prusa's award-winning Original Prusa i3 MK2 3D printer.

We have further upgraded the MK3S with a brand new SuperPINDA sensor 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 MK52 heatbed with removable PEI spring steel print sheets, numerous sensors, power loss recovery (power panic) and safety features. And it is still as silent as ever!

The functionality of the MK3S can be further expended with our unique Multi-Material Upgrade 2S addon for printing with up to 5 materials simultaneously.


Original Prusa MINI+

Smart and compact 3D printer for everyone

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 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.


Premium-quality filaments and resins

Prusament is our own in-house made filament. The advanced manufacturing process allows for higher level of quality control, more efficient testing and a guaranteed manufacturing precision of less than 0.02 mm (the industry standard is generally higher).

Each spool of the filament have a perfect winding and it's meticulously tested. The complete manufacturing reports are available online, enabling customers to see detailed properties of every spool they have purchased. Prusa Research is the only company providing its customers with this unique option.

The range of materials under the Prusament brand was expanded with high-quality in-house-made resins in 2021.



Community makerspace/hackerspace

Opened in June 2018, PrusaLab is a maker's dream come true. A fully equipped makerspace/hackerspace (creative open space) stretches over an area of 350 m² and it is available to everyone for a low monthly membership fee.

3D printers, CNC Vertical Mill Haas VF2SS, CNC Toolroom Lathe Haas TL-1, Narran Laser cutter, saws, drills, pliers, hammers, electro-workshop items... no matter how complex your project is, we've got you covered! Plus, you can take part in various workshops, lectures or listen to industry-related talks.

Prusa Research offers its 3D printers to Czech schools

We have launched a new program for schools and educational institutions called "Prusa pro skoly" (Prusa for schools). The aim of this program is to provide various institutions with discounted Original Prusa 3D printers, filaments, resources for teachers, pre-made exercises and specific ideas on what to do with a 3D printer in school.

"Our goal doesn't end with simply selling a 3D printer to a school. There's so much more. I believe that most teachers are open to modern technologies, but with their daily workload it may be difficult to learn everything on their own. The equipment is often bought just so it can collect dust on a shelf. That is why we want to create a platform that will allow teachers to share their projects with each other, consult problems and solve them," says Josef Průša, CEO of Prusa Research.


Prusa PRO Face Shield

PRUSA PRO Face shield is the final version of our face shield (successor to the Prusa Face Shield RC3).

This shield provides complete protection of the entire face (flying drops, sprayed liquids) and has passed the official certification procedure according to the standards. It provides not only frontal protection (like the RC3 version), but protection on the sides as well. The Prusa PRO Face Shield meets the standard of EN 166:2001 for protection against drops and sprays (protection class 3).

Customers from EU countries can order certified version of this shield in our eshop. Or you can print PRUSA PRO Face shield yourself.


Helping in the fight against COVID-19 with Prusa Face Shields

With the arrival of the COVID-19 pandemic, the demand for personal protecive equipment (PPE) skyrocketed. We joined the worldwide fight and shared our open-source protective shield design so anyone can download it for free and manufacture face shields using a 3D printer. We have also started producing the face shields and donated over 200.000 in-house produced shields to doctors, firefighters and other frontline staff. We have also summarized our findings, precautions and safety measures in blog posts to inspire other companies or individuals and to help them in difficult times.
