Original Prusa MK4S Printer with Canadian ETL Safety Certification

Significant Features:

Perfect dimensional accuracy

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

360 deg 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.

Solid and Durable Prints

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.

Perfect Surface Finish

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.

World-Class Print Speed

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.

Seamless Workflow

You can control your printer(s) remotely. The MK4S includes an ethernet port and Wi-Fi with NFC setup, allowing you to manage it from anywhere using the secure Prusa Connect system or mobile app. For maximum security, the printer can also operate fully offline.

Advanced Materials

Choose the best filament for your model, the MK4S can handle most of them: PLA, PETG, ASA, carbon-filled filaments, and even the flexible TPU! With its direct drive Nextruder, it tackles TPU easily, allowing you to create amazing flexible projects. To get the most out of your materials, house the MK4S in an Enclosure.

100% Privacy

We do not collect information about your prints or your printer’s surroundings without consent. We believe that no matter whether you’re developing a new-generation space shuttle, or just printing silly things for your friends, no organization should be interested in this information. This is why our printers can be found in top companies, universities and research institutions around the world.
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.

Available Add-ons:

MMU3: MK4S can be enhanced by an optional add-on that allows your single-extruder printer to print with up to five colours (materials) at the same time. Load the five colours of your choice, slice the object in PrusaSlicer, start the print, and let the MMU3 do the rest.

With all-new plastic parts, reinforced metal parts and firmware built from the ground up, the MMU3 delivers stunning multi-material prints faster and more efficiently than its competitors. With 25-35 seconds per filament change and optimized nozzle cleaning, the prints are beautifully fast and reliable, and you don’t have to worry about cleaning piles of wasted filament scraps from around your printer all the time.

The MMU3 is up to three times more efficient in managing filament waste compared to other single-nozzle multi-material systems, bringing substantial cost savings.

Enclosure: If you want to print more advanced technical materials on your MK4S, you’ll find the Enclosure really handy. It stabilizes the printer environment, eliminates drafts and odors, and makes the printer even more silent.

An enclosure is not necessary for every type of filament. Most of common materials, such as PLA, PETG, and even some advanced ones (like PCCF) do not require an enclosure. However, once you need to print with more advanced materials, such as ASA, ABS, PC and similar, the Enclosure is the best option to achieve increased temperatures in a stabilized environment, plus, the optional high-performance filtration system will take care of ultra-fine particles.

The Original Prusa Enclosure is available with a range of useful add-ons, such as the Advanced filtration system with HEPA filter, LED strip, or Mechanical Lock. You can add these addons manually to the shopping cart. 

Accessories: The MK4S is compatible with two new optional addons for enthusiasts and modders. First, the GPIO “hackerboard” allows you to control external electronics using G-commands. And we have also introduced an accelerometer add-on for those who made extensive changes to the Nextruder. You can find more details on their respective product pages.
