PHA

Standard Plastics
FunctionalSustainableUV resistant

PHA (Polyhydroxyalkanoate) filament is a biodegradable type of plastic used in 3D printing, made through the fermentation of plant sugars by bacteria. It's known for being environmentally friendly, making it a great choice for applications that require biodegradability, such as disposable items and medical implants. PHA is more flexible and has better UV resistance compared to PLA, making it suitable for outdoor use. It also degrades more easily in natural environments than ABS, offering a greener alternative without the need for special conditions or toxic chemicals for breakdown.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

4 colors

Standard (as-printed) PHA parts have a flexible, rubbery surface rather than rigid FDM texture. Layer-line visibility and support-mark behavior may differ from standard rigid FDM materials.

Sanded

Sanded

4 colors

The sanded finish on FDM parts reduces the visibility of layer lines compared to the standard finish, though some surface texture generally remains. How much smoothness is achieved can vary depending on the material.
