I am on contract for 3d carving , 2 sided , 200 each of 5 different parts
We originally were going to make them out of Valchromat. Valchromat is a resin based mdf that comes in different colors. It worked ok for some of the parts. They all are thin Walled and some have tabs that keep breaking off. so we are looking for a material thats stronger
Here are some pictures of one of the parts

I am mostly experienced in working in wood so not familiar with other material such as HDU and PVC.

Any suggestions ?
