Ep040: 3D Printed Everything, Strength v Toughness, Blades of Fiber, and What Can't Coffee Do?
Hackaday editors Mike Szczys and Elliot Williams discuss the launch of the Prusa Mini 3D printer, noting its 180mm build volume and 32-bit STM32 processor. They highlight research from Washington State University on adding 20% coffee grounds to PLA filament to increase impact toughness by 400%, and showcase several 3D-printed mechanical projects, including a hoverboard-powered tracked robot and a high-torque servo gearbox. The episode also covers the disposal challenges of carbon fiber wind turbine blades and the repurposing of vintage VTech toy computers containing Z80 processors.
