Clearly I need hominid casts made of stainless steel:
Shapeways, a company that made its name offering custom 3-D printing in plastic and resin, will now print your designs in stainless steel. All you have to do is upload your brilliant CAD design (or pick from a range of stock items). Shapeways will print it out in cold, shiny steel, and mail it to you.
It ain’t cheap – $10 per cubic centimeter. But I suppose they’re dishwasher safe.
