The Original Prusa MK4 is designed with a host of innovative features that cater to both novice and experienced users alike. One of its standout features is the new Nextruder, a redesigned extruder system that incorporates a dual-gear mechanism for more precise filament control. This is particularly beneficial when working with flexible filaments like TPU, which can be challenging to print with due to their bendy nature. The Nextruder’s design ensures consistent and reliable extrusion, reducing the risk of jams and other common issues associated with flexible materials. Additionally, the quick-swap nozzle system allows users to easily change nozzle sizes without needing tools, enabling seamless transitions between fine detail work and faster, more structural prints.
The MK4 also introduces a new Loadcell sensor for bed leveling, which eliminates the need for manual adjustments. This sensor measures the force applied to the print bed during the leveling process, ensuring a perfectly smooth first layer every time. This feature is particularly valuable for beginners, who may find manual bed leveling a frustrating experience, as well as for seasoned users who want to save time and improve print consistency.
Another key feature of the MK4 is its connectivity options. The printer supports USB, Wi-Fi, and Ethernet connectivity, allowing for remote monitoring and control. However, it’s worth noting that utilizing the Wi-Fi and Ethernet features requires additional software, which can complicate the setup process. Despite this, the MK4’s connectivity options are a significant upgrade from previous models, providing users with more flexibility in how they manage their prints.
The MK4 also maintains Prusa’s commitment to open-source design, which allows for extensive customization and modification. This is a crucial feature for hobbyists and makers who enjoy tinkering with their machines. The open-source nature of the MK4 means that users can easily find and share modifications, upgrades, and custom settings within the Prusa community, making the printer not just a tool, but a platform for innovation.
Design & Build Quality

Visually, the Original Prusa MK4 retains the classic black-and-orange aesthetic that has become synonymous with Prusa printers. However, beneath its familiar appearance lies a significantly more robust machine. The MK4 features a thicker aluminum frame compared to the MK3, providing increased stability, which is crucial when operating at the higher speeds the MK4 is capable of. This added rigidity helps to minimize vibrations, leading to more precise prints even during fast operations.
The open-frame design remains a hallmark of the Prusa series, allowing for easy access to the print bed and extruder. This accessibility is particularly beneficial for users who enjoy tinkering with their machines or making quick adjustments during a print. Additionally, the redesigned extruder carriage and improved bed-leveling system contribute to the MK4’s enhanced reliability and ease of use. The touch screen, a new addition to this model, simplifies navigation through settings and makes the printing process more intuitive, even for beginners.
Power & Performance

When it comes to performance, the Original Prusa MK4 does not disappoint. One of the most significant improvements over its predecessor, the MK3, is the speed. The MK4 is capable of printing at speeds up to 600mm/s, a considerable upgrade that allows for much faster print times without compromising quality. This is particularly important in today’s 3D printing landscape, where speed has become an increasingly critical factor. With the addition of Input Shaper support, the MK4 can maintain high print speeds while minimizing vibrations and ringing, ensuring that the final prints are both fast and flawless.
The MK4’s power doesn’t just lie in its speed; it also excels in precision and accuracy. The Nextruder system, combined with the new Loadcell sensor for bed leveling, ensures that prints start with a perfect first layer and maintain high quality throughout the build. This level of precision is crucial for detailed prints, such as intricate models or functional parts that require tight tolerances. The MK4 consistently produces prints with smooth surfaces, sharp details, and strong layer adhesion, making it a top choice for users who demand the best possible print quality.
In terms of versatility, the MK4 is capable of printing with a wide range of materials, including PLA, PETG, ABS, ASA, and flexible filaments like TPU. The printer’s all-metal hot end can reach temperatures up to 290°C, which expands its material compatibility and allows it to handle more advanced filaments that require higher extrusion temperatures. Additionally, the heated build plate can reach temperatures up to 120°C, further enhancing the printer’s ability to work with a variety of materials, including those that are prone to warping, like ABS.
While the MK4’s performance is undeniably impressive, it’s important to acknowledge that it comes with a few caveats. For instance, some users have reported issues with stringing, particularly when using the default temperature settings in PrusaSlicer. This can be mitigated by adjusting the print temperatures, but it highlights the importance of fine-tuning the printer’s settings to achieve optimal results. Despite these minor issues, the MK4’s overall performance remains top-notch, making it a powerful tool for both hobbyists and professionals.
Ease of Use

One of the most appealing aspects of the Original Prusa MK4 is its ease of use, making it a strong contender for both novices and experienced users. The printer arrives almost ready to go out of the box, with only minimal setup required. The pre-assembled version, in particular, is ideal for those who want to start printing as quickly as possible without the hassle of assembly. For those who prefer a hands-on approach, the kit version offers a rewarding build experience that can deepen your understanding of the machine’s inner workings.
PrusaSlicer, the accompanying software, is another highlight. It’s designed to cater to all skill levels, with different modes that range from simple to expert. The simple mode is perfect for beginners, while the more advanced modes provide a wide array of customization options for users who want to fine-tune their prints. The inclusion of comprehensive and well-illustrated documentation further enhances the user experience, ensuring that even complex procedures are easy to follow.
Conclusion: Should You Buy the Original Prusa MK4?
The Original Prusa MK4 is a formidable 3D printer that upholds Prusa’s legacy of delivering high-quality, reliable machines. Its blend of speed, precision, and ease of use makes it an excellent choice for both beginners and seasoned makers. While the price may be on the higher side, particularly for the pre-assembled version, the MK4 justifies the cost with its performance and feature set. If you’re in the market for a versatile, open-source 3D printer that can handle a wide range of projects with ease, the Prusa MK4 is a worthy investment.
