PHA 3D Printing Filament & Pellets — Biodegradable Printing Material
Biodegradable additive manufacturing material supplied as 1.75 mm and 2.85 mm filament or as pellets for direct pellet extrusion printers. The formulation targets MFI 3-15 g/10min, giving smooth extrusion at 170-200°C nozzle temperature with low warping and good interlayer adhesion — the two failure modes that make most biodegradable filaments difficult to print. Heat resistance to 140°C is well above PLA, so printed parts can be used in warm environments without softening. Medical grade resin is available for prototypes and tooling that contact skin or food.
Key Benefits
- Low warping prints reliably on open-frame machines without an enclosure
- Good interlayer adhesion reduces delamination on functional parts
- Heat resistance to 140°C, well above PLA, for warm-environment use
- Diameter tolerance ±0.03 mm prevents extrusion jams and flow variation

Frequently Asked Questions About PHA 3D Printing Filament & Pellets
What is PHA 3D Printing Filament & Pellets made of?
PHA 3D Printing Filament & Pellets is made from 100% PHA (Polyhydroxyalkanoates), a bio-based polyester produced by bacterial fermentation of renewable feedstock. Unlike petroleum-based plastics, PHA is derived from non-food plant sugars using Chinese indigenous bacterial strains. The material is certified by BPI, TUV Austria (OK Compost HOME, OK Compost MARINE), and DIN CERTCO for complete biodegradation in ocean, soil, home compost, and industrial compost environments.
How long does PHA 3D Printing Filament & Pellets take to biodegrade?
PHA 3D Printing Filament & Pellets biodegrades completely within 6-18 months in home compost. In industrial composting facilities (58°C+), degradation occurs in 3-6 months. In marine environments, complete biodegradation takes 1-3 years. The process produces only CO2, water, and biomass — no microplastics or toxic residues remain.
What certifications does PHA 3D Printing Filament & Pellets hold?
PHA 3D Printing Filament & Pellets holds BPI, TÜV OK Compost HOME, OK biodegradable MARINE, FDA 21 CFR, ISO 9001. These certifications verify that the product meets international standards for biodegradability, compostability, and food contact safety. PHApack products are tested per EN 13432, ASTM D6400, ISO 14855, and ASTM D6691 standards by independent laboratories.
What is the minimum order quantity and lead time?
The standard MOQ for PHA 3D Printing Filament & Pellets is Trial orders from 100 kg. Lead time is typically 15-25 days after order confirmation. For custom OEM orders with specific dimensions, colors, or branded printing, lead time may extend to 25-35 days. Trial orders from 100kg are available for evaluation.
Can PHA 3D Printing Filament & Pellets be customized with our brand logo?
Yes, PHApack provides full OEM/ODM services for PHA 3D Printing Filament & Pellets. Customization options include custom dimensions, colors, flexographic printing up to 6 colors, private label packaging, and branded embossing. Our R&D team can also develop custom PHA formulations tailored to your specific application requirements, including MFI optimization and additive packages.
