3D-Printed Parts Don’t Slow Down This Speedy Printer



Truth be told, we generally find speed sports to be a little boring. Whether it’s cars going around in circles for hours on end or swimmers competing to be a few milliseconds faster than everyone else, we just don’t feel the need for speed. Unless, of course, you’re talking about speedy 3D printers like “The 100” , which claims to produce high-quality prints in a tenth the time of an ordinary printer. In that case, you’ve got our full attention.
What makes [Matt the Printing Nerd]’s high-speed printer interesting isn’t the fact that it can do a “Speedboat Run” — printing a standard Benchy model — in less than six minutes. Plenty of printers can do the same thing much, much faster. The impressive part is that The 100 does it with a 3D-printed frame. In fact, most of the printer’s parts are 3d printed, a significant departure from most speed printer builds, which generally shy away from printed structural elements. [Matt]’s design also aims to keep the center of gravity of all the printer’s components within a very small area, which helps manage frame vibrations that limit print quality. The result is that the CoreXY gantry is capable of a speed of 400 mm/s and an eye-popping 100,000 mm/s² acceleration. What also sets [Matt]’s printer apart is that The 100 is designed to be a daily driver. It has a generous 165 mm x 165 mm print bed, which is far more useful than a bed that’s barely bigger than a standard Benchy.
The video below has much more details on the open-source build, plus some nice footage of some speed runs. The quality of the prints, even done at speed, is pretty impressive. Perhaps there is a point to speed sports after all.
