The T250: Built for extreme speed
Developer Matthäus Szturc has introduced theT250a printer that has only one goal: maximum speed in FFF (Fused Filament Fabrication) process. And the results are impressive: A complete Benchy is created inless than two minutes.
But how is such brutal performance even possible? Here are the technical highlights:
1. CoreXY system and brutal acceleration
The T250 is based on an extremely rigid frame and a CoreXY kinematics driven by four motors. The result? An acceleration of up to250,000 mm/s²– that's about 25 times what a standard desktop device achieves.
2. Pure power: 60 volts instead of 24 volts
While most hobby printers operate at 24 volts, the T250 takes it a step further. The motors are powered by60 voltsThis higher voltage allows for extremely fast speed changes and ensures that the mechanics can be pushed to their physical limits.
3. Cooling at High-End Level
Those who print quickly have a problem: The material stays soft for too long. If the next layer comes before the previous one is solid, it ends in chaos. The T250 therefore uses aCPAP-like cooling. With high air pressure, the airflow is directed around the extrusion zone to solidify the filament immediately. Even the motors are actively cooled to manage the heat.
High-end performance at a low-budget price?
The best thing about the T250: It is a true community project. The design data isOpen Sourceavailable. According to the developers, the material costs amount to onlya few hundred dollars.
However, one should not expect an "out-of-the-box" experience. The T250 is a pure DIY project. It requires craftsmanship in assembly and a good deal of finesse in calibrating the Klipper firmware.
Conclusion: The boundaries are shifting
The T250 impressively shows what is possible today in the DIY sector. With 600 mm/s for outer walls and up to 1,500 mm/s for the infill, it proves that "Open Source" does not mean "slow" at all.
Anyone looking for a challenging DIY project and wanting to break speed records in their own workshop should definitely take a closer look at this project.
