PLA/PHA is a unique blend developed by Colorfabb, this filament is tougher and less brittle than PLA. PHA is a bio-polyester like PLA, this means that this blend is 100% biodegradeable.
These Colorfabb filaments are available in 1.75mm and 2.85mm, in a large variety of colors.
It’s a very nice filament, with high quality results. The diameter is very constant, which gives a nice constant flow when printing.
