Aluminium comes in untreated surface only. Plus it is very susceptible to fingerprints. How about decorative anodizing aluminium parts? First to seal the surface, second to obtain colors. Did you think about offering this service?
I may be wrong, but as far as I know the Al commonly used for DMLS is a silicon-rich alloy composition that is not suitable for decorative anodizing.
Thank you for your suggestion @wolfgang.schroeppel! We have looked into this in the past but ultimately decided against including it in our offering.
Anodizing parts in DMLS aluminium is indeed not straightforward to do.
That is also the reason why it is not in our standard offer as Stephanie indicated.
Ok, thanks, so I better look for some paint then.
