Metallics and other materials
Everyone uses different methods to create the finished products. In powder bed technology, the components are built up layer by layer. This is done by melting parts of each powder layer with a laser or electron beam. This technology is used not only for metallic products, but also for the manufacture of products in polymers and other materials.
Research is needed
Mechanical properties of components manufactured using additive manufacturing may differ from those of components manufactured using conventional techniques. This depends on the inherent complexity of the techniques and on many different process parameters, such as layer thickness, energy density, scanning strategy, build speed and preheating temperature.
In order to introduce additive manufacturing for critical and highly stressed products, it is necessary to understand how the process affects, for example, fatigue properties and damage resistance.
The project is a collaboration with IMA, SAAB, Siemens Energy, AM Printservice, Curt Nicolin Gymnasiet, Etteplan, Interspectral and Swemac.
