18 months ago, a 3D printing enthusiast challenged himself with the task of printing a 3DBenchy in under a minute. Over the weekend, the first sub-60-second 3DBenchy output was shared on YouTube. Join Yan Roetz on the final furlong of this 3D printing journey (the 20th episode) and understand the motion, heat, and cooling challenges that had to be overcome. The Final Barrier in High-Speed 3D Printing is Broken! (Minuteman FINAL Episode 20) - YouTube Watch On Roetz was already the holder of the 3DBenchy world speed record, adhering to SpeedBoatRace rules, with a time of 74 seconds. He recognized that shaving another 15 seconds off that time would need considerable design changes to the specially designed Minuteman 3D printer. The three main considerations behind a successful under-a-minute attempt were thought to remain the same – maintaining rapid material flow, capable cooling, and an optimized motion system.…
