Blending thermoplastic polylactide (PLA)with polyhydroxyalkanoate (PHA)enables the formulation of a more mechanically powerful material and this enables tailored biodegradation properties. In this study we demonstrate the 3D printing of a PLA/PHA blend as a potential candidate for biocompatible material applications. The filament for 3D printing consisted of PHA, which contains predominantly 3-hydroxybutyrate units and a small amount of 3-hydroxyvalerate units, as revealed by multistage mass spectrometry (ESI-MSn). This research found that the properties of 3D printed species before and during abiotic degradation are dependent on printing orientation. Furthermore, the 3D printed specimens exhibited good biocompatibility with HEK293?cells, indicating real promise as biological scaffolds for tissue engineering applications.14aTHREE-DIMENSIONAL PRINTING14aLAYER ORIENTATION14aDEGRADATION14a(BIO)DEGRADABLE POLYESTER14aTOXICITY TEST14aCELL PROLIFERATION12aAusejo, J.
