Powder Bed Fusion of Polyolefins
Polyolefins are a class of engineering polymers primarily comprised of polyethylene and polypropylene. These polymers offer especially desirable chemical resistance and mechanical properties. They are unique in that they generally crystallize more rapidly than polyamides, which are the most used polymers in powder bed fusion. The DREAMS Lab works to connect fundamental material properties of these polymers to process parameters within the Powder Bed Fusion system. Powder flow, coalescence and crystallization are each studied to optimize part production for these materials.
