I’m looking at AlphaSTAR’s GENOA 3DP simulation suite, a tool for assisting professional additive manufacturing production.

 .

I’ve been working in additive manufacturing / 3D printing for over 12 years, and I am still constantly surprised by the complexity of the additive manufacturing, and the consequent challenges facing equipment operators.

 .

This is particularly evident in powder-based additive manufacturing processes such as SLS, DLMS and EBM, where environmental characteristics can hamper achievement of successful prints unless all factors are precisely balanced.

 .

For example, in metal 3D printing processes, tremendous heat is applied when lasers sinter the fine metal powder. This heat is significantly higher than that of surrounding powder, creating a rather large heat gradient that can create damaging forces within the print. In many cases these forces can cause warped parts, dimensional inaccuracies and even cracks, all not good. Sometimes the flaws do not appear until after the print completes; […]
