Predicting mechanical property plateau in laser polymer powder bed fusion additive manufacturing via the critical coalescence ratio

Predicting mechanical property plateau in laser polymer powder bed fusion additive manufacturing via the critical coalescence ratio

The state of the art in property-process relationships in the laser polymer powder bed fusion (LPPBF) subcategory of powder bed fusion (PBF) has derived relationships between the energy supplied and polymer thermal properties governing melting and degradation, so-called the “energy melt ratio (EMR)....
