Warranty note:
Consumable parts, such as print sheets (smooth, textured, etc.), are not covered by the warranty since their coatings are expected to deteriorate over time, unless the failure is due to a defect in materials or workmanship. Cosmetic damage, which includes, but is not limited to, scratches, dents, cracks, or other aesthetic damage, is also not covered. Only sheets defective upon delivery are covered by the warranty.
Description
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.
Perfect for Pros and Beginners
The MK4S answers your needs whether you're just starting or have years of experience. We've designed the UI to be easy to use even for complete beginners, yet its reliable performance also makes it a perfect fit for professional workshops. Getting started is super easy: simply take the MK4S out of the box, plug it in, perform a quick calibration, and start printing in 15 minutes!
Unmatched Print 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.
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. See the accuracy comparison measured using a CT scan:
The more the color deviates from green, the less accurate the object is. The MK4S is the clear winner.
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.

Solid & 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.
The MK4S prints require low-to-no finishing.
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.

Proven Reliability
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%! Don't believe it? Check out our Trustpilot score or Google Reviews!
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.
Accessories for enthusiasts
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 addon for those who made extensive changes to the Nextruder. You can find more details on their respective product pages.
Open design - simple maintenance
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.
Designed for Offline Use
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 Nextruder & 32-bit Platform
The MK4S is built on the internally developed 32-bit embedded platform and features our next-generation extruder, the Nextruder.
Add-ons
MMU3
MK4 can be enhanced by an optional add-on that allows your single-extruder printer to print with up to 5 colors (materials) at the same time. Load the five colors 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.
The high-flow nozzle in the MK4S allows for much faster printing. However, when using the MMU3, the standard nozzle makes much more sense. Why? While the MMU3 works fine with a high-flow nozzle, the increased volumetric flow results in higher filament waste during printing. In other words, the MMU3 delivers the best performance, the same speed and the highest efficiency (lowest waste) when combined with the standard nozzle in both MK4 and MK4S. So, if you order a standalone MMU3 for the MK4S you will receive it along with the standard nozzle. In the MK4S/MMU3 bundle, you will receive both nozzles in the package - the standard one as well as the high-flow nozzle. For assembled MK4S in a bundle with MMU3, the standard nozzle will be pre-installed on the printer as the default.
Enclosure
If you want to print more advanced technical materials on your MK4, 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, Mechanical Lock or Fire Suppression System. You can add these addons manually to the shopping cart. Find out more in the Enclosure Addons section on our e-shop.
