3D printing with spent coffee grounds, 3D prints with an internal resistor network for multi-point sensing and bio fiber spinning were some incredible projects that I found at the Rocky Mountain RepRap Festival 2023 in Loveland, Colorado. The Utility Research Lab of the ATLAS Institute from the University of Colorado Boulder had a booth there and displayed some of their impressive projects to the public.
