Researchers Develop a Geometry-based Model for Predicting Lack-of-Fusion Porosity in PBF 3D Printing Processes

by Design

A study which appeared on the ScienceDirect Journal describes the development of a geometry based model for predicting lack of fusion during metal powder bed fusion processes (SLM, DMLS, EBM). The model relies on melt pool dimension, hatch spacing and layer thickness. The porosity (or density) predicted with the model agrees well with reported literature data on PBF processes.
