Simulation Models for 3D Inkjet Printing – Material and Process Design

Due to the ability to produce complex parts with no need for pre-tooling, Additive Layer Manufacturing (ALM) is a future technology with 3D inkjet printing being one of them. The latter is based on the polymerization of a liquid dispensed into a powder bed. However, the special challenges which have to be met here are to increase product quality such as tensile strength and density on a repeatable base. Consequently multi-scale simulation models were developed to support material researchers as well as users of the technology in their daily work and therefore to contribute to process stability and material reliability of 3D printers and their products.
