360° Cooling – Print without Supports

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.

World-Class Print Speed

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.
