Product Description
Prusa MK4S is the latest edition of PRUSA's flagship 3D printing workhorse. It combines the reliability and safety features of its predecessors with high-speed performance enabled by Input Shaper support. It brings plenty of new features like a perfect smooth first layer thanks to the Loadcell sensor (no manual adjustments needed), remote printing, quick-swap nozzles, customizable UI with a one-click printing option, and much more.
The MK4 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.
The package includes a Smooth PEI print sheet.
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 modder
* With the MK4S/MMU3 bundle, you will receive both nozzles in the package - the standard and the high-flow nozzle. Assembled MK4S in a bundle with MMU3, the standard nozzle will be pre-installed on the printer by default.

Customer Reviews
Don't even wonder twice about Zerse or Prusa - just click buy!
I ordered a Prusa MK4 kit from Zerse and received it - along with 2 spools of Prusament that I ordered only 4 days before shipment - all within a week. Exceptional service from Shaun and what really impressed me was the test sheet in the box showed the printer had been tested in the factory 7 days prior to me opening the box - no old stock being pushed at discount prices - fresh from the factory in record time at the best price I could find online. Brilliant!
The MK4 is a work of art and I really gained more and more appreciation for the machine whilst building it from the detailed online instructions. Price aside - if you can read and work a screw driver - the kit is the option to go for.
Thanks again Shaun for going the extra mile.
I received my Prusa MK4 kit within a week through the fantastic service of Zerse. They were also on hand for advice during the build and first prints.
It took me 3 days to carefully build the Prusa MK 4 kit and it worked perfectly first time round! Thank goodness. It’s a fantastic printer with noticeable better quality than the cheaper alternatives. The self-build was painful though and not worth the saving in my option. Next time I’ll order the allready-assembled one.
Got my printer on time and a free hardened steel nozzle. I was helped through the build process by the team at Zerse
Putting this together was quite fun. Prusa has an entire forum to help you thorught the build.
