Hello,
We think that Polyamide (SLS) would be okay. This is an exceptionally versatile, strong, and slightly flexible material. It can resist a small degree of impact and some pressure while being bent. Depending on the design, it can be flexible or rigid. The surface has a sandy, granular look, and is slightly porous. However, a lot of colors and finishing options are available, from color dyeing and polishing, to flocking and waterproofing.
Polyamide is a great material for beginners who want a well-priced model and extensive freedom of design. You can find out more about this material on our website on https://i.materialise.com/en/3d-printing-materials/polyamide
Kind regards Lizy
