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.
We publish new updates for our printers even years after release, bringing new, often major features that transform the way you print. The MK3S+ kept receiving firmware updates for more than six years. The Original Prusa MINI received a major Input Shaper update four years after release, which doubled its print speed. The MK4S is the newest iteration of our proven MK4 platform.
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!
No matter whether your project requires PLA and PETG, or even ASA and carbon-filled filaments, the MK4S can handle them with ease - even flex! With its direct drive Nextruder, printing flexible materials is easier than ever before and you can create amazing flexible projects without breaking a sweat (or your printer). Most materials do not require an enclosed printing space, but for those that do, there's a dedicated Enclosure.
Our machines are built to last. We operate a massive print farm with over 700 of our printers running 24/7. This means we design our machines to withstand non-stop operation with minimal downtime. The open “bed-slinger“ design is the result of a 10-year evolution and enables the easiest access to all parts without a lengthy disassembly process. No welded or glued parts, everything can be taken apart with a set of Allen keys.
The MK4S has been designed for native offline use, so if you don’t want to use the network services, you don’t have to. The printer can be configured completely without internet access and there are no drawbacks or limitations. The Wi-Fi module can be easily unplugged for environments that require the highest level of security.
The MK4S is built on the internally developed 32-bit embedded platform and features our next-generation extruder, the Nextruder.
Our printers are primarily designed for completely offline operation with no drawbacks or limitations. You have the option to share data with our tech support and connect your printer to the Prusa Connect remote print management system, but only if you choose to do so)
Our code is open source, so you can always check that we aren’t cheating or stealing your files, even when you’re connected to the internet.
