Original Prusa MK4 3D Printer kit

Twice as fast as the MK3S+ and among the fastest desktop printers, the MK4 uses a native implementation of Input Shaper and Pressure Advance technologies to eliminate resonances and optimize filament flow. The result is doubled print speed and beautifully quiet operation, so you can keep the MK4 on your desk and continue working undisturbed. Check out the sub-20-minute Benchy video!

Speed is nothing without quality and reliability. There's no point in chasing speed records when the prints barely hold together. While the MK4 is twice as fast compared to its predecessor, we put extra care into improving the print quality even further.

The MK4 uses redesigned, more robust plastic parts, thicker 10mm Z-axis rods and new precise 0.9°; stepper motors (0.9°; / step; low inductance) to eliminate Vertical Fine Artifacts on prints. The next-generation extruder (Nextruder) delivers exceptionally good performance especially with extremely steep overhangs up to 15° and easily handles even flexible filaments. The overall precision of the printer ensures you can print parts that fit perfectly together.

No matter whether your project requires PLA and PETG, or even ASA and carbon-filled filaments, the MK4 can handle them with ease - even flex! With its direct drive Nextruder, printing flexible materials is easier than ever before and you can create amazing flexible projects without breaking a sweat (or your printer). Most materials do not require an enclosed printing space, but for those that do, there's a dedicated Original Prusa Enclosure (see below).

Forget Live Adjust Z or manually adjusted screws. The MK4 lays down an absolutely pristine first layer every time. It doesn't matter what kind of print surface you use, the MK4's Loadcell sensor will always precisely measure the offset without being thrown off by reflective or textured surfaces. The sensor doesn't rely on visual data, offering unparalleled precision on every kind of print sheet out there!

The Original Prusa MK4 is equipped with a Wi-Fi module and an ethernet port, allowing you to control your printer from anywhere using our secure and encrypted Prusa Connect system. Drop a G-code into your browser window and start the print in mere seconds after the beginning of the upload. Prusa Connect offers a robust set of options, allowing you to schedule your prints, or monitor them remotely via a webcam.

We publish new updates for our printers even years after release, bringing new, often major features that transform the way you print. The MK3S+ kept receiving firmware updates for more than six years. The Original Prusa MINI received a major Input Shaper update four years after release, which doubled its print speed.

Our machines are built to last. We operate a massive print farm with over 700 of our printers running 24/7. This means we design our machines to withstand non-stop operation with minimal downtime. The open “bed-slinger“ design is the result of a 10-year evolution and enables the easiest access to all parts without a lengthy disassembly process. No welded or glued parts, everything can be taken apart with a set of Allen keys.

The MK4 has been designed for native offline use, so if you don’t want to use the network services, you don’t have to. The printer can be configured completely without internet access and there are no drawbacks or limitations. The Wi-Fi module can be easily unplugged for environments that require the highest level of security.
