I would like to make my own business cards by inking up a custom stamp and whacking it into card stock. I'll get both an embossed and inked card with a whack of a hammer. I was wondering if the 3D printed steal could do the trick. I would take my business card design and bring it into 3dmax, extrude the design onto the z axis and expand one facing edge to taper the details into a wider base and finally a back plate of 1/4 inch of steal. I think this configuration respects the sandcastle structure rule - when the metal is still being held together with glue. Questions! if i have details on the surface of the card which are 1pt wide will the metal cut into the card or will the card blunt the metal? I'll be happy if the stamp produced 1000 good impressions also will the shift from glue to bronzing phase alter the surface and leave me with a stamp that dose not lie flat? if so - what are the margins, will a hammer whack make those tolerances negligible? Is the metal brittle? would repetitive strikes shatter the stamp - would adding a rubber backing help?
