Original Prusa MK4S 3D Printer

Description

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!

Plug and Print!

With automatic calibration, one-click printing and an always-perfect first layer, the MK4S is the best entry into the world of 3D printing. Its open design, the result of more than 10 years of evolution, ensures easy maintenance, upgradability and great accessibility. Plus, a detailed handbook guides you through every aspect of the MK4S. When you get the assembled printer, simply take it out of the box, plug it in and once it finishes the automatic calibration, you can start printing right away!

Quiet High-Speed Printing

Twice as fast as the MK3S+ and among the fastest desktop printers, the MK4S uses a native implementation of Input Shaper and Pressure Advance technologies to eliminate resonances and optimize filament flow which is further enhanced by the new high-flow nozzle. The result is doubled print speed and beautifully quiet operation, so you can keep the MK4S on your desk and continue working undisturbed. The MK4S can print a SpeedBoatRace Benchy in 14 minutes and a “Bonkers” Benchy in 8 minutes.

Exceptional Print Quality and Reliability

Speed is nothing without quality and reliability. There's no point in chasing speed records when the prints barely hold together. While the MK4S is twice as fast compared to the previous generation, we put extra care into improving the print quality even further.

With the redesigned 360° cooling, high-quality high-flow nozzle, robust parts, and fine-tuned print profiles, the MK4S delivers exceptionally good performance with precisely directed cooling, extreme 75° overhangs, and easily handles even flexible filaments. The MK4S offers the best dimensional accuracy, enabling you to print parts that fit perfectly together.

High-Performance 360° Cooling

The MK4S features a brand new 360° cooling system consisting of a high-performance turbine and a redesigned fan shroud - the result of intensive airflow simulations to ensure that the cold air is directed precisely onto the print. This solution is much more effective compared to blanket fans, because the airflow is not blocked by the print itself. The weight of the Nextruder remains virtually unchanged, but the performance is far better.

Even with the large turbine, the printer is still beautifully quiet and can deliver prints with extreme 75° overhangs. Why does this matter? Because where other printers would already need a hefty amount of supports, the MK4S can easily deliver a beautiful-looking print. Less supports means shorter print times and less material wasted.
