This collection of 3D-printed forms are bio-inspired, bio-based, and bio-degradable. Each biomaterial is derived from local bio-waste streams (e.g., eggshells, fallen leaves, orange peels) to create pastes that can be extruded from 3D printers. Our process diverts local biomaterials away from becoming waste by repurposing them into beautiful objects that are biodegradable and can return to the soil. The forms are created using Python code and a clay 3D printer. We generate parametric forms inspired by tree trunks, garlic cloves, and sea shells that function as birdhouses, plant pots, and vessels. They highlight the importance of regenerative and temporary art and objects in a world that is constantly generating waste. They challenge us to consider how art and science can participate in circular processes with benefits beyond the immediate present.
