Quality

In order to improve the reliability and shape accuracy of all products generated by addititve manufacturing, we develop individual security systems for your entire product development process.
Using its long-term and cross-sector expertise, the Fraunhofer Additive Manufacturing Alliance supports you in integrating quality assurance tools as well as in installing and optimizing your quality management systems.

Simulation of residual stresses and warpage in stereolithography

Resins for stereolithography shrink during polymerization. During the layer wise curing this leads to residual stresses and warpage

Strain rate dependent material behavior for dynamic loads

Additively manufactured materials are analyzed in experiment and simulation. In particular, the strain rate dependence of the material behavior is investigated which is of high relevance for special load cases like car crash.
