colorFabb's allPHA 3D printing filament (pronounced “Alpha”) is the ultimate bioplastic. Polyhydroxyalkanoates, abbreviated as PHA, are created through a naturally occurring process called fermentation. By feeding bacteria natural sugars and oils, the bacteria form “fat cells” (PHA). The best part about PHA? Microorganisms can break it down again at the end of the product's life.

Their allPHA material completely degrades in all biotopes without leaving microplastics. The degradation rate depends on the thickness of the printed object as well as composting conditions such as heat, moisture, and microbial activity. This makes allPHA very different from PLA, which is only biodegradable in industrial composting environments.

allPHA exhibits excellent layer-to-layer adhesion under most printing conditions. The material feels robust and durable and is stable at very high temperatures (>120 °C). Unlike other filaments, allPHA must be printed on a cold build plate with 100% fan cooling. As an added benefit, an unheated build plate allows for much more economical and sustainable printing, as it saves a significant amount of energy during the printing process.

allPHA is an excellent material for projects that require a more sustainable approach. With multiple end-of-life options and a natural ability to "disappear back into nature," allPHA is a truly circular material.

This filament is delivered on a cardboard spool made from recycled cardboard to further minimize the use of single-use plastics.
