Computational Modeling of Additive Manufacturing by Power Bed Laser Fusion: FY19 Engineering Research Technical Investment Program
Abstract
Additive manufacturing (AM) or 3D printing has had a huge impact on numerous sectorsat scales ranging from microfabrication to big area manufacturing (size of meters). Many predictthat it will soon be recognized as the technology behind the third industrial revolution. It is definedby the ISO/ASTM as the process of joining materials to make parts from 3D model data, usuallylayer upon layer, as opposed to subtractive and formative manufacturing methodologies. Withadditive manufacturing, parts of complex geometry can be built with a single machine operationand without any special masks, tooling, dies, or fixtures. Originally used primarily for fabrication ofprototypes and models of design concepts, various AM methods are presently capable of producingfunctional devices, components, and structures constructed from numerous types of materials.
