Biodegradable 3D Printing Filament
Prints like traditional filaments, but composts at home or in soil
Compostable 3D Printing Filament
Compostify's biodegradable filament delivers high-quality 3D prints without the environmental cost. Our patent-pending PLA–PBSa–PHA blend performs reliably and lasts as long as you need it—but when you're done, it fully biodegrades in soil or compost within six months, leaving no microplastics or toxins, just nutrients.

Cheaper, Better and Biodegradable
Why Choose Biodegradable Filament?
Conventional PLA is marketed as “biodegradable” but requires industrial facilities that most users don’t have access to. Compostify filament is different: it biodegrades in real-world conditions, including soil and backyard compost. That means your failed prints, supports, or retired parts can safely return to the earth — eliminating disposal costs and environmental impact.
Key Advantages for Makers & Businesses:
- End-of-Life Solution: Compost failed prints and prototypes at home.
- Performance: Smooth surface finish, reliable layer adhesion, and predictable shrinkage.
- Sustainability: Gain an edge with eco-conscious clients demanding plastic-free solutions.
-
Compliance Ready: Anticipates stricter rules on plastic use in design, prototyping, and packaging.
