Abstract Scope |
Additive manufacturing (AM) is enabling a revolution in digital design capabilities. Optimized geometries can retain certain specified properties while reducing unnecessary weight. These optimization practices often form organic-looking shapes that could not be fabricated through any conventional means, though the new design comes with a corresponding increased risk of AM build failure. Process simulation is one way to anticipate these risks; and select commercially available software tools now detect distortion and recoater blade crashes in laser powder bed fusion (LPBF) processes. A recent study has focused on understanding the capabilities and limitations of these AM simulation tools. The example design is a conformally shaped pressure vessel put through various evolutions of internal design changes, including wall-thinning and optimized internal struts. This presentation outlines observations from both the simulations as well as validating physical builds of this pressure vessel as the design evolved. |
