Manufacturing process combines advantages of 3D printing and injection moulding
Scientists at Fraunhofer IPA have developed a process that combines the advantages of 3D printing and injection molding. In additive free-form casting, the shell of the component is first produced with the known FLM pressure die-cast process and then filled with a two-component resin via 3D printing. This saves time, increases the stability of the component and makes it possible to process new materials. The method suits in particular for electrically isolating products in complex shapes.

With additive free-form casting, researchers at the Fraunhofer IPA (Stuttgart, Germany) devised a way to reduce the disadvantages of the widely used FLM (fused layer modelling) process. These disadvantages include suboptimal mechanical properties and high time expenditure. In addition, only certain materials, the so-called thermoplastics, can be processed with this method.
