Breathe 3DP Blue PLA++ claims to be less brittle than standard PLA, though I have not seen any testing. Printing worked fine with my standard PLA settings. This color is a cobalt blue. Located in Virginia, USA, Breathe 3DP is developing advanced materials in-house such as colored nylons. The PLA++ comes in 1KG size on a plastic spool.
