...announcement a couple of months down the line:
"Supply your custom punch design and we'll make chips with them! *
* no guarantees on product stability"
Well, probably not
But when I first read that you were planning to try 3D printer prototyping for punches, I got the idea to try make a set of cookie cutters that would work the same way. Multiple punches for multiple edge spot designs, and some sort of stamp punch to apply a "mold" design on one side.
I'm not sure if answering this would touch trade secrets or not... Do you use separate punches for punching the holes in the chip bodies, and for punching the actual spots from different-colored clay? Also - if the soft clay was about as sticky as butter cookie dough - do the punches have some sort of mechanism to push out parts that get stuck inside the punch?
Since the traditional metal punches are so expensive, I assume you'd use the same punch for both applications - which seems to be very inefficient for me to punch just the spots as there would be so much waste material left over. I somehow doubt it'd be possible to just gather all the leftover scraps from a color and roll a fresh plate from that?
If the 3D printed punches are stable enough to last for a reasonable amount of time, it might be worth it to make separate punches for the spots that would punch many at a time and arranged in a way that produces as few leftover scraps as possible. Might reduce production costs and workload. I'm definitely going to try this when I draw the designs for the cookie cutters. Still going through some AutoCAD video tutorials
