I would like to prototype a deep drawn part from 1.5mm thick 304 Stainless Steel. It measures approximately 300mm x 300mm x 30mm deep with a rim all around it â€“ just like a baking tray! There are also some text and other features (a brand logo) that need to be bashed into the main bottom face. Any ideas how to prototype such a part cheaply? Iâ€™m worried this could get expensive.
