As powder is added on layer by layer, more heat is applied, which can create localized heating and cooling stresses, leading to undesirable microstructures and, ultimately, suboptimal properties.
New Mold Deformation Analysis calculates the effects of filling pressure and cooling stresses on the mold and the part.
The sharper the corner, the more subject it is to crack-like ruptures due to cooling stresses or mechanical nicking, and, ultimately, failure in fatigue.
Cooling stresses present only a part of the picture in the case of excessive wall thickness variations.
