As much as the future of rapid prototyping with 3D printing looks bright, not all printing filaments are sustainable like this one from WillowFlex.
This additive manufacturing material uses a base of non-GMO corn starch to form an elastomeric bioplastic from compostable raw materials. After a 3D-printed creation has served its purpose, the materials can be set in the ground to decompose for a number of months. It's described that WillowFlex has the ability to "set a new baseline for filaments used in sensitive environments such as schools, homes and kitchen, and medical applications."
Other noteworthy eco-friendly printing filaments that are beginning to emerge include Agridust made from food waste, Refil made from used car dashboards and PET bottles and 3D Systems' water-soluable Infinity Rinse-Away.
