Beyond Plastic PHA Filament FlexPHA

Please note: Beyond Plastic has shut down their filament division and there is no more PHA from them in the market that we are aware of. We are looking for alternatives, including working with the former Beyond Plastic team to bring to market an alternative source.

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 Gen 2 PHA filament formula 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 PHA is a great alternative to PLA and other plastic filaments when it comes to 3D printing.

Recyclable, compostable, and biodegradable: Our PHA 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.
