Prusa Research, a pioneer in the 3D printing industry, unveiled their Prusa MK3.5. Building upon the success of the MK3, the MK3.5 introduces a host of improvements and innovations that promise to elevate the 3D printing experience. In this article, we will delve into the enhancements that set the MK3.5 apart from its predecessor, exploring the features that make it a noteworthy addition to the world of 3D printing.

Upgraded Extruder Assembly:

Improved Bondtech Gears: The MK3.5 features an upgraded extruder assembly with Bondtech gears, enhancing filament grip and reliability. This improvement ensures smoother filament feeding, reducing the likelihood of jams and improving overall print quality.

Enhanced Cooling System:

Upgraded Noctua Fan: The MK3.5 incorporates a Noctua fan for better cooling efficiency. This fan design contributes to quieter operation while maintaining optimal cooling for the hotend and heat sink. Improved thermal management helps prevent heat-related issues during prolonged print sessions.

Revised Y-Axis Frame:

Sturdier Frame Design: The MK3.5 introduces a revised Y-axis frame, providing increased stability and rigidity. This enhancement contributes to more precise and accurate prints, particularly during high-speed movements and complex geometries.

Upgraded Magnetic Bed Surface:

New Magnetic Spring Steel Sheet: The MK3.5 features a revamped magnetic bed surface with a spring steel sheet, providing improved adhesion and facilitating easier print removal. The flexibility of the spring steel sheet allows users to flex and pop off prints effortlessly.

Silent Trinamic Stepper Motor Drivers:

Reduced Noise Levels: The MK3.5 incorporates Trinamic TMC2209 stepper motor drivers, which operate more quietly than their predecessors. This improvement enhances the overall user experience by reducing the noise generated during 3D printing, especially in home or office environments.

Thermal Upgrades for the Hotend:

Enhanced Thermal Dissipation: The MK3.5 introduces thermal upgrades to the hotend, ensuring more effective dissipation of heat. This enhancement contributes to greater temperature stability, minimizing the impact of temperature fluctuations on print quality.

Continued Support for Multi-Material Printing:

Seamless Multi-Material Printing: The MK3.5 retains compatibility with the Multi-Material Upgrade (MMU), allowing users to seamlessly print with multiple filaments. This feature enables the creation of intricate, multi-colored, and multi-material prints.

The Prusa MK3.5 stands as a testament to Prusa Research's commitment to innovation and continuous improvement in the 3D printing landscape. With upgrades to the extruder assembly, cooling system, frame design, magnetic bed surface, stepper motor drivers, and hotend, the MK3.5 offers a comprehensive set of improvements over its predecessor, the MK3. This printer not only maintains the high standards set by Prusa but also introduces features that cater to the evolving needs of the 3D printing community. As the MK3.5 finds its way into the hands of enthusiasts and professionals alike, it is poised to make a significant impact on the quality and versatility of 3D printing projects.
