Z-PHA is a polyhydroxyalkanoate bioplastic 3D printing filament. It’s one of the most eco-friendly filaments available on the market as it is easily biodegradable and produced by bacteria kept under certain conditions. Z-PHA has shrinkage lower even than PLA-based materials, so it is perfect for 3D printing large, yet dimensionally accurate models like architectural mock-ups.
The filament is more durable and stronger than PLA so it is recommended whenever better mechanical properties are needed apart from immense precision. Z-PHA is not recommended for high-temperature environments. Exposure to chemicals should also be avoided.
