Great support

We are an established company founded in 2012, and we work hard to help you start 3D printing as soon as possible. We are providing full 24/7 customer support with live chat and e-mail in several languages. There are also unofficial user groups on Facebook, where makers help each other. You will never be alone in the big world of 3D printing!

The kit comes along with a forum support where our ever growing community can always help, or you can even get in touch with Jo Prusa himself at the very same spot! Check out the forum and regularly updated Knowledge Base!

With 3D printing, buying a printer is just a beginning!

Fun to assemble

Assembling the kit is an excellent first step to the world of 3D printing. You will understand the principles of printer construction and get a huge advantage when you need to solve possible problems and replacements later.

But don't worry. Assembling is quite easy! You don't have to solder at all to build our kit. You don't even have to own a soldering iron. All our cables are cut to length and with professionally crimped connectors. And from the electronics standpoint, the hardest thing will be plugging the connectors to the motherboard.

All of this makes the kit very friendly to younger builders :-)

Best assembly instructions and free 3D Printing handbook

We didn't want to leave anything to chance, so our assembly instructions are pictured to the smallest detail.

See the assembly manual for yourself!

All fasteners and mechanical parts have 1:1 drawing so you can easily find them, and there is no chance of you picking a wrong one. You don't have to be MIT graduate to assemble our kit ;-)

Our fastest customer built the kit in 4 hours! Will you beat him?

Ready to print settings

We provide high print settings with the printer, so you don't have to dive into complex new programs the second you finish the build. You can start printing right away, and this gives you a great head start!

These settings are great for all kinds of objects, not just for a couple of prepared showpieces. After a while, when you're familiar with the printer, you can, of course, dive into tinkering ;-)

We are developing our own slicing software. In Slic3r Prusa Edition you can set everything you want. PrusaControl on the other side is focusing on casual users, and it's very easy to use. But of course, we also have the settings for the third party slicers like Simplify3D, Cura, etc.

Upgradability

One of the most popular features of Original Prusa i3 concept is upgradability. If you buy our 3D printer, you can upgrade it later to the new version, so you don't need to buy the whole new model every two years as you get used to for example with your phone or laptop. :-)

Upgrades are a great way not only for saving money, but also to learn about the construction of the printer's hardware. We are constantly improving our technology. A few years ago there was the Original Prusa i3 3mm which was upgradable to the Original Prusa i3 Plus 1.75mm (MK1). This printer can become MK2S thanks to the next big upgrade and then you can go even for the latest MK3 (or MK2.5 if you wish).

Ready for the Multi Material

Original Prusa i3 MK3 Multi Material is the unique consumer option to print with up to 4 different materials simultaneously. The use of up to 4 material feeders with only one hotend makes the solution calibration free and much easier to use than currently available systems.

Multi-material could be your next step in the 3D printing world and MK3 is completely ready for the upgrade.

BTW: Do you know, that you can easily print soluble interface supports with Multi Material upgrade? We have a pretty smart solution for you - check out the video!

Quality guaranteed by Josef Prusa & Prusa Research

Prusa Research is a 3D printing company based in Prague, Czech Republic. It was founded by Josef Prusa, one of the core developers of the Open Source project RepRap, in 2012 as a one-man startup and grows to a 160+ team now.

The open-sourced Prusa i3 design is according to 3DHubs the most used 3D printer in the world.

Today we are shipping more than 6000 Original Prusa i3 printers per month to over 120 countries directly from Prague.
