Ecogenesis Soleic^® Thermoplastic Polyurethane (TPU) redefines sustainable innovation as the world’s first fully biodegradable, flexible TPU filament for 3D printing. Derived from plants and certified by USDA BioPreferred, Soleic^® TPUs combine cutting-edge performance with exceptional environmental responsibility.

Our TPU filaments come with a carbon footprint reduction, ranging from 77.8% to 83.8%, and they are chemically designed to completely biodegrade in the most sensitive ecosystems, including our waterways and oceans.¹ At the end of their life these materials leave no harmful microplastics behind.² Following modified ASTM D5338 methodology, shredded TPUs have been mixed with compost and incubated at 45°C. After 180 days, the materials have achieved 27% absolute biodegradation as measured by CO₂ respirometry. These results set a new benchmark for biodegradability in a flexible filament.

Beyond their sustainability credentials, ecogenesis Soleic^® TPUs offer the same strength, flexibility, and softness of conventional TPU filament, and will maintain these properties until their end of life.
