The University of Colorado Assistant Professor Micheal Rivera found a way to use coffee grounds for 3D printing. Mixing the caffeinated by-product with a few ingredients enabled him to create sturdy, biodegradable projects once they harden. Rivera hopes it inspires others to discover other sustainable 3D printing techniques. More people want to create a sustainable, environmentally friendly future, but we need new ideas to make that possible. We must find new ways to recycle or repurpose waste products, and this coffee 3D printing method is one of the most interesting ones right now.
