The use of biobased plastics is of great importance for many applications. 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. [-]
