In accordance with Atieh Moridi, an assistant professor of Mechanical and Aerospace Engineering at Cornell University, told Digital Trends“Conventionally, achieving full density in prints is desirable to avoid the deterioration of mechanical properties associated with pores such as reduced strength. However, in this study, porosity was intentionally induced by working within a lower particle velocity range called the subcritical velocity regime, where the material deposition efficiency is below 100 percent.”
