Original Prusa MK4S 3D Printer

Fast and accurate results without compromise

Original Prusa MK4S delivers reliable results for all your projects. Based on the MK4, beloved by hobbyists and large companies alike, it offers even higher precision and printing speed. Thanks to the new 360° cooling, high-flow nozzle, and numerous firmware optimizations, you'll get your 3D models rapido and with the highest quality.

Perfect for professionals and beginners

The MK4S meets your needs, whether you are just starting out or have years of experience. We designed theuser interface to be easy to use even for beginners, but its reliable performance makes it perfect for professional labs as well. Getting started is super easy: just take the MK4S out of the box, plug it in, perform a quick calibration, and start printing in 15 minutes!

Unmatched print quality

Despite being our fastest printer, the MK4S never sacrifices quality for shorter print times. Thanks to its optimized features and workflow, it always produces accurate models at amazing speeds, as confirmed by the perfect score of 30/30 in Print Quality in TechRadar's review.

Perfect dimensional accuracy

Your creations should turn out exactly as they were designed, especially when they require a perfect fit. The MK4S ensures this with exceptionally accurate prints. Look at the comparison of accuracy measured with a tomographic scan:

The further the color deviates from green, the less accurate the object.
MK4S is the clear winner.

360° Cooling - Media-free printing

Reduce the need for media and print faster with less material! With 360° cooling, the MK4S allows you to print protrusions up to 75° without media, greatly reducing costs and printing time. This also simplifies printing flexible materials such as TPU, where media removal is often challenging.

Robust and durable prints

With the MK4S, prints last. The new cooling fan and high-flow nozzle ensure excellent adhesion of layer, making prints stronger and more durable. It comes with a wide range of print profiles that allow you to favor higher speed or maximum strength.

Perfect surface finish

Patterns look smooth and pleasing to the eye as the MK4S's printing profiles favor perfect surface finishes. You can adjust the height of the layer print profiles to the level of detail you want and print anything from super intricate patterns (with the 0.25 mm nozzle) to larger objects where details are less important.

MK4S prints require no finishing.

Top-notch print speed

As Tom's Hardware says: The Prusa MK4S is damn fast. It greatly reduces print times thanks to a new cooling fan with a powerful turbine and 360-degree air delivery, as well as a high-flow nozzle that maximizes filament flow. Combined with optimized firmware and print profiles, results are fast and flawless.

Proven reliability

We ship about 10,000 3D printers per month directly from our headquarters in Prague, Czech Republic, and have started manufacturing them in the United States as well. There are over half a million Original Prusa printers in circulation, and yet only about 20 printers per month need to be sent back for maintenance-the complaint rate is less than 1%! Can't believe it? Take a look at our Trustpilot score or Google reviews!

Seamless workflow

You can control the printer(s) remotely. The MK4S has an Ethernet port and Wi-Fi with NFC configuration, allowing you to manage it from anywhere using the secure Prusa Connect system or mobile app. For maximum security, the printer can also operate completely 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 flexible TPU! With its Direct Drive Nextruder, it can easily handle TPU, allowing you to create incredible flexible designs. 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 add-ons for enthusiasts and modders. First, theGPIO "hackerboard" allows you to control external electronics using G commands. In addition, we have introduced an accelerometer addon for those who have made substantial modifications to the Nextruder. More details are available on the respective product pages.

Open design - easy maintenance

Our machines are designed to last. We operate a huge print farm with more than 700 printers running 24/7. This means we design our machines to withstand non-stop work with minimal downtime. The open "bed-slinger" design is the result of a 10-year evolution and allows the easiest access to all parts without a lengthy disassembly process. There are no sealed or glued parts; everything can be disassembled with an Allen wrench set.

Designed for offline use

The MK4S is designed for native offline use, so if you do not want to use network services, you do not have to. The printer can be set up completely without Internet access, and there are no drawbacks or limitations. The Wi-Fi module can be easily disconnected for environments that require the highest level of security.
