Optimization of heat treatment on additively manufactured components to replicate aluminium HPDC mechanical properties

The objective of this research project is to produce additively manufactured aluminum components by selective laser melting with similar mechanical properties as aluminum high-pressure die-cast (HPDC) parts. Since as printed parts usually present better tensile mechanical properties than die-cast ones, a heat treatment cycle specifically optimized for this application will be looked into in order to reduce these properties. This will allow production of prototype die-cast components for testing in shorter lead times and with less monetary commitment. With this knowledge in hand, Dyna-Tool will be able to provide a faster response to the die-casting industry compared to the usual practices for production of prototypes, as well as having the same bulk mechanical properties. Canada exports many HPDC parts worldwide. Therefore, Dyna-Tool will be able to accelerate the prototyping phase in the die-casting industry, thus increasing the response to the need for many Canadian businesses.
