Enthusiast 3D printer builder Yan Roetz has achieved a new world record by printing the standard 3DBenchy test model in just 59 seconds. The Minuteman printer reached this milestone through a comprehensive overhaul of its bed motion system, which significantly reduced moving mass and inertia to enable extreme acceleration rates.
Revamped bed motion system enables extreme acceleration rates.
The achievement required extensive mechanical modifications beyond stock configurations. Roetz replaced key structural components with carbon fiber parts and fabricated custom-cut elements specifically designed for high-speed operation. These changes allowed the printer to overcome previous physical limitations that capped print speeds at higher durations.
Core performance capabilities were already sufficient before this record attempt. The Minuteman hotend supports 400mm/s filament flow rates, while its cooling air duct system delivers approximately 400 liters of air per minute. These specifications provided the necessary thermal management foundation for rapid printing operations without compromising material integrity.
The printer maintained good print quality despite the aggressive speed increase. Roetz shared footage showing the first sub-60-second output achieved with improved surface finish compared to earlier high-speed attempts. The result demonstrates that extreme acceleration does not necessarily sacrifice dimensional accuracy or layer adhesion when properly tuned.
This achievement breaks the previous world record of 74 seconds for the same test model. The Minuteman design had already pushed boundaries in rapid prototyping, but this modification represents a distinct leap in practical speed capabilities. The accomplishment highlights how targeted mechanical improvements can unlock performance previously thought constrained by physics.
