The effects of processing parameters on mechanical properties of 3D-printed polyhydroxyalkanoates parts

open access: yesVirtual and Physical Prototyping, 2023
The crystallisation process of polyhydroxyalkanoates (PHA) polymers plays a key role on final properties of manufactured parts due to most PHA are highly sensitive to physical aging which leads to embrittlement.
