Ambrosia PHA Filament 1KG 1.75mm - Earth Friendly Filament for Everyone

We are pleased to re-release PHA filament under our Ambrosia Brand in partnership with ecogenesis bipolymers genPHA®. This filament is MADE IN THE USA!

PHA is a biopolymer made from natural materials. It looks, feels, and works just like plastic — but unlike other plastics it’s environmentally safe and leaves zero microplastics behind. 

Our genPHA® filament formula, developed by ecogenesis biopolymers, improves mechanical properties so there’s no need to compromise between quality and sustainability. Now makers can get high-quality precision prints that are smooth, consistent, and eco-friendly every time.

Here are the reasons genPHA® is a great alternative to PLA and other plastic filaments when it comes to 3D printing.

Recyclable, compostable, and biodegradable: Our genPHA® filament is recyclable, compostable, and biodegradable under all conditions. This means that it can be safely placed in a home compost bin along with food and waste. And even in the worst-case scenario, if it ends up in landfills or our oceans, it will naturally biodegrade. 

Quality Performance: Improved bed and layer adhesion and overhang, while decreasing die swelling, ensuring more accurate and consistent prints.

Easy to use: Clog-free, bubble-free formula with low warpage and shrinkage, guaranteeing smooth prints for every project.

While this filament is not suitable for food contact, it is phthalate-free, BPA-free and is CPSIA compliant. There are no chemicals contained in our PHA listed under California's Prop 65! (as of 9/24/2025).
