研究目的
To achieve the desired effect on the aluminium’s surface quality with robotized laser heat treatment equipment and to show that the used finishing treatment method could be automated or robotized.
研究成果
The study showed that the surface quality of the AlSi10Mg parts produced by SLM can be altered with a disk laser assisted heat treatments. Several parameter sets for the laser treatments were tested and found applicable and the glass bead blasting could be used to further improve the surface quality. It was shown that the studied parameter sets have clearly better impact on the surface quality when the initial quality is rougher.
研究不足
The main challenge arose from the SLM method and the inconsistent surface quality between the parts and build orientation. Surface quality straight from the platform is affected by many variables, most notably the location on the build platform, powder quality, and the orientation of the surface to the build direction.
