PHA 3D Printer Filament, FlexPHA™ Black


Note: Max total quantity of 3 allowed per order

FlexPHA™ is a 100% biodegradable, recyclable and compostable Polyhydroxyalkanoate, semi-crystalline thermoplastic produced from microorganisms by fermentation of renewable carbohydrate feedstocks. From nature, back to nature.

Beyond Plastic PHA 3D Printer filament, Black, 1kg/600g Spool, Dimension Accuracy = 1.75 +/- 0.1 mm

Material Technical Data Sheet

• Good processability and stable melt flow in most 3D Printers.
• Suitable for flexible prototypes similar to tire rubber. This material does not have a performance similar to a rubber band.
• Soft material
• Nontoxic fumes
FlexPHA™ is phthalate free, BPA free and CPSIA complaint.
• It does not have any chemicals listed on California's Proposition 65.

PREMIUM FILAMENT without the hassle or the negative environmental impact. Designed by professionals for extremely high-detail resolution.

NO GREENWASHING. NO exaggerated claims. NO hidden trade-offs. NO carbon credit off-sets.

A fully commercialized 100% biodegradable PHA polymer; Beyond Plastic 3D Printer filaments return to the earth as bio-mass particulates that are consumed by naturally occurring micro-biomes in the environment. All other so-called "recyclable" and "bio-degradable" plastic/polymer materials breakdown into harmful micro-plastics that will never fully reabsorb into environmentally friendly byproducts.

EASY-TO-USE filament fluidly fits into any 3D printer model with the toughness and durability needed for accurate and precise design work. NO bubbling, NO clogging, NO warping, and odor free. 

FULLY RECYCLABLE SPOOL made from recycled paperboard so that all parts of the product are truly biodegradable.

NOTE:  Color variations in the final product may occur due to the natural color variations in our raw materials.  Quality and technical specs are not affected by variations in color.
