These upgrades ensure superior print quality while significantly reducing printing times. Whether you’re working on intricate designs or functional prototypes, the MK4S delivers exceptional results.  

Easy to use for all skill levels

Whether you’re new to 3D printing or a seasoned professional, the MK4S is ready to meet your needs. Its intuitive interface simplifies operation, allowing you to unbox, calibrate, and begin printing in just 15 minutes. This makes it an excellent choice for workshops, schools, and hobbyists alike.  

Exceptional print quality

The MK4S achieves remarkable print accuracy without sacrificing speed. Its advanced features ensure smooth, precise models that require minimal post-processing. It has been recognised for its outstanding performance, including a perfect score in print quality from industry reviews.  

Dimensional accuracy you can trust

Precision is critical when your designs demand perfect fits. The MK4S excels in producing dimensionally accurate models, validated through rigorous testing such as CT scans, making it ideal for technical and functional prints.  

360° cooling for better overhangs and flexible materials

The MK4S’s 360° cooling system reduces the need for supports, enabling overhangs up to 75° without compromising quality. This feature saves time and materials, particularly when working with flexible filaments like TPU, which can be challenging to finish with supports.  

Durable and robust prints

The MK4S ensures excellent layer adhesion for sturdy and long-lasting prints with optimised cooling and a high-flow nozzle. Customizable profiles allow you to prioritize speed or durability depending on your project needs.  

Top-class surface finish  

Achieve stunning aesthetics with the MK4S, which delivers smooth, detailed surfaces. From intricate models using a 0.25mm nozzle to larger-scale projects, the MK4S adapts to your desired level of detail with precision.  

Unmatched print speed

Thanks to advanced cooling and optimized filament flow, the MK4S substantially reduces print times without sacrificing quality. Whether you’re working on tight deadlines or large-scale projects, this printer ensures quick and reliable output.  

Proven reliability

With over half a million Prusa printers in use globally and an exceptionally low return rate, the MK4S stands out for its reliability. Each unit is manufactured in the EU or the USA and undergoes rigorous quality control to meet the highest standards.  

Seamless connectivity and workflow

The MK4S offers remote control through an Ethernet port, Wi-Fi, and NFC setup. Use the Prusa Connect system or mobile app for secure, streamlined management. For offline operation, the printer works flawlessly without internet access, providing complete privacy and security.  

Advanced material compatibility  

The MK4S handles a wide range of filaments, from PLA and PETG to more advanced options like carbon-filled composites and flexible TPU. Pairing it with an enclosure further enhances performance with materials that require controlled environments, such as ABS or ASA.  

Privacy by design

Your projects remain confidential with the MK4S. It operates offline by default, ensuring no data is shared without consent. Its open-source design allows you to verify security and customize its functionality as needed.  

Accessories and modular upgrades

Enhance the MK4S with optional add-ons like the GPIO hackerboard or accelerometer for advanced modifications. Additionally, the MMU3 upgrade enables multi-material printing with minimal filament waste, making complex projects more efficient and cost-effective.  

Built to last with easy maintenance

The MK4S features an open design for straightforward access and maintenance. With no glued or welded parts, every component can be disassembled using standard tools, ensuring longevity and ease of use for years to come.
