Josef Prusa, the founder of Prusa Research, recently made an exciting announcement regarding the Mini 3D printer. In a blog post, Prusa revealed that they have successfully made the Mini printer much faster by porting the MK4 firmware to the Mini’s CPU and smaller RAM.

The Mini is known for being the smallest and least expensive 3D printer from Prusa Research. It has been well-received for its output quality at an affordable price. However, like many other 3D printers at the time, it lacked speed, running at a relatively slow pace of 40-80mm/s.

In the past few months, there has been a high-speed revolution among 3D printer manufacturers. New firmware technology has allowed for faster printing speeds without compromising quality. This has become the standard for many new desktop 3D printers entering the market.

Meanwhile, most of us still have “slow” 3D printers on our desks. Some of us have the Prusa Mini, a popular choice for hobbyists and enthusiasts. This has changed thanks to Prusa Research’s innovative firmware development.

Prusa Research has been focusing on their new flagship 3D printer, the MK4, which offers high-speed printing capabilities. However, it required a firmware update to achieve these speeds. To stay competitive in the market, Prusa Research took on the challenge of porting the high-speed firmware to the Prusa Mini, despite its lower storage and processing capabilities.

The firmware is still in the early stages of development and is currently classified as “alpha.” This means that there is a risk of failure when using it. Prusa Research expects the final firmware to be released in about a month. Until then, Mini owners can download and try the alpha version at their own risk.

The benefits of the new firmware are evident, as demonstrated by Prusa Research’s ability to print a #3DBenchy in just 16 minutes on an upgraded Mini. Previously, this print would have taken over an hour to complete, showcasing a potential 4X increase in speed.

The key feature of the firmware responsible for this speed increase is “input shaping.” It analyzes the requested movements and adjusts the stepper motors in real-time to compensate for vibrations during high-speed printing. This not only allows for faster printing but also improves print quality.

However, it’s important to note that the Mini was not originally designed to withstand high-speed movements or high-volume deposition. Its compact and efficient design did not prioritize robustness. Therefore, while the speed increase is impressive, the overall performance may not match that of dedicated high-speed printers.

Nevertheless, this upgrade is a fantastic addition for Mini owners and should be considered once the official release is available. Prusa Research is providing this upgrade free of charge, highlighting their commitment to enhancing the user experience.

Overall, Prusa Research’s announcement of faster printing speeds for the Mini 3D printer is exciting news for the 3D printing community. It demonstrates the company’s dedication to innovation and ensuring their products remain competitive in a rapidly evolving market.
