Assistance materials

I have a really precise question.
We already printed a project with your company. The result was really nice but it needs few adjustements about the materials (and I do not know much about materials).
The first object is a rectangle (150.5 x 94.0 x 4.0 mm) made in ABS / White. The problem is that the finish is rough and this is not convienent for cleaning. The object should be rigid, not too heavy and not deformable (at 37°C). What material do you suggest ?
The second part is a cube (20.0 x 20.0 x 20.0 mm) made in Stainless steel / Old silver. We observe some corrosion/rust. It should be not too heavy and not deformable (at 37°C). What material do you suggest ?
Thank you very much.

Hi Alicia,

Based on details of models’ intentional use I’d suggest you to check out SLS or MJF based materials:

Polyamide would be with smoother surface than Alumide and more flexible, adjustable if needed. Alumide is a rigid material and the surface is a bit more granular, but still smoother than ABS.

Meantime, if you are considering metals, Aluminum could be the solution (no rust): https://i.materialise.com/3d-printing-materials/aluminum/
