NEW USER GUIDES FOR THE ORIGINAL PRUSA I3 MK3S

Welcome to the growing family of the Original Prusa i3 MK3S owners! Thank you again for purchasing a 3D printer directly from its developer Josef Prusa. Your purchase supports us in further development. Josef Prusa, one of the core developers of open source project RepRap and creator of Prusa i3, started Prusa Research as a one-man startup in 2012. The company rapidly expanded and now has a team of more than 350 people. Currently, we ship more than 6000 Original Prusa i3 printers per month to over 160 countries directly from Prague. And we continue to improve both user experience and reliability of 3D printing every day.

However, a 3D printer is not a maintenance-free machine - at least not yet. You need to learn a few things about how a 3D printer operates, so you can enjoy trouble-free printing or even solve an occasional problem, such as a clogged nozzle. But don't worry! Most problems are really easy to fix. Plus, we are here to help you. This page contains links to a whole bunch of useful videos and articles, which will guide you through your first steps in the 3D printing world. Some of them are for more advanced users, but no worries - you'll be one of them soon enough 😉

In case you can't find the answer to your question on our websites, we are providing full 24/7 customer support via live chat (available at shop.prusa3d.com) and e-mail in several languages. There are also unofficial user groups on Facebook, where makers help each other.
