Powder metallurgy sintering process has the following steps. Eros, Asteroid: Overview, History & Discovery | What is 433 Eros? Sinter hardening is an accelerated cooling process that increases the metals hardness to improve resistance to deformation under stress. In SLS printing technology the 3D model is printed between the powder raw material layer by layer thus there is no need for supports to hold overhangs or other parts of the model. Traditionally, people think that high-temp sintering utilizes temperatures of 2100-2300F. The tighter the weave, the harder it is to breathe and for particles to move through.
