Prusa Research Original Prusa MK4S 3D Printer Kit

The MK4S is the latest iteration of our flagship 3D printing workhorse. Easy to set up and run, with top-class reliability and safety features, the MK4S delivers the highest quality 3D prints faster than ever. Designed and built in the EU.

Starting with 3D printing has never been easier! Take the printer out of the box, plug it in, let it run a quick Selftest, and start printing! No assembly required. With automatic calibration, always-perfect first layer, one-click printing and many other useful features, the MK4S is the best choice for your home, workshop, or company. All print profiles and configurations are in-house tested ensuring that the MK4S effortlessly delivers top-quality 3D prints at a press of a single button from the very start.

With an optional enclosure (available also in bundle with printer) and multi-material upgrade, you can expand your experience as you go, and print with advanced materials or create beautiful multi-colored prints!

Original Prusa MK4 vs MK4S

Every Original Prusa 3D printer receives long-term support for years after launch. Not just small bugfixes, but major firmware and hardware upgrades that bring useful new features. And MK4 is no exception.

Compared to the Original Prusa MK4, the MK4S brings the following innovations:

• New high-performance 360° cooling system
• High-quality high-flow nozzle as standard*
• Native iOS/Android Prusa app for iOS and Android with easy Wi-Fi setup with an NFC tap
• Improved print speed
• Improved print quality
• New parts printed from Prusament PC Blend Carbon Fiber or injection molded
• Optional accessory: GPIO hackerboard
• Optional accessory: accelerometer for printer modders

The MK4S provides high-speed 3D printing with ease and is ever so reliable like all Original Prusa 3D printers. It has all the best features of the popular MK3/S/+ – an open-source 3D printing workhorse with easy maintenance and advanced safety features – and adds much more!

The MK4S 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.

Smooth PEI print sheet included

Original Prusa MK4S is built around our new 32-bit connected architecture and the next-generation extruder (Nextruder). It lays down a perfect first layer every time without Live Adjust Z and it has support for high-speed printing with Input Shaper and Pressure Advance. We also improved the safety features even further. Plus, there are a ton of useful things, such as quick-swap nozzles, built-in support for remote printing and webcams, and many more. And it’s still beautifully quiet.
