Original Prusa MK4S 3D Printer

Original Prusa MK4S 3D Printer

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.

Fast and Precise Results without Compromise

The Original Prusa MK4S delivers reliable results for all your projects. Building on the MK4 model loved by hobbyists and big companies alike, it offers even higher accuracy and print speed. Thanks to its new 360° cooling, high-flow nozzle, and numerous firmware optimizations, you’ll get your 3D models fast and with top-notch quality.

While the MK4S is our fastest printer yet, it never sacrifices quality for quicker print times. Thanks to its fine-tuned features and workflow, it always delivers precise models at amazing speeds as confirmed by the perfect 30/30 score in Print Quality in TechRadar’s review.

Your creations should turn out precisely as designed, especially when they require a perfect fit. The MK4S ensures that by delivering exceptionally accurate prints.

Reduce the need for supports and print quicker with less material! Thanks to the 360° cooling, the MK4S allows you to print overhangs of up to 75° without supports, significantly cutting down on print costs and time. This also simplifies printing flexible materials like TPU, where removing supports is often a challenge.

With the MK4S, you get prints that last. Its new cooling fan and high-flow nozzle provide excellent layer adhesion, making your entire prints strong and durable. It comes with a wide array of print profiles that let you prioritize higher speed or maximal sturdiness.

Your models turn out smooth and a joy to look at, as the MK4S’ print profiles prioritize perfect surface finishes. You can adjust print layer height to match your desired level of detail and print everything from super intricate models (with the 0.25mm nozzle) to larger objects, where details matter less.

As Tom’s Hardware puts it: The Prusa MK4S is pretty darn fast. It substantially cuts print times thanks to the new cooling fan with a powerful turbine and 360° air delivery, as well as the high-flow nozzle that allows for maximized filament flow. Combined with optimized firmware and print profiles, the results are both quick and flawless.

We ship around 10,000 3D printers each month directly from our HQ in Prague, Czech Republic, and we also started manufacturing them in the USA. There are over half a million Original Prusa printers in the wild and still only around 20 printers per month need to be sent back to us for hands-on maintenance – the claim rate is less than 1%!
