Abstract

The present invention is directed to certain biodegradable and/or compostable biobased particulate compositions for additive manufacturing, such as those including a polyhydroxyalkanoate (PHA) powder, wherein the particulate composition and/or the PHA powder possesses (a) a free bulk density, as determined by ASTM D1895-96, of greater than 0.30 g/mL, and (b) a sinterability region of greater than 15 degrees Celsius. Also, the invention is directed to certain methods of manufacturing such biodegradable and/or compostable biobased particulate compositions useful as powdered build material for additive manufacturing processes. In addition, the present invention is directed to additive manufacturing processes utilizing the biodegradable and/or compostable biobased particulate compositions elsewhere described, along with the articles printed therefrom.
