I would like to have a different six to seven digit number displayed on each of my already printed parts and I have no clue how to do it. Maybe someone here can enlighten me. It's almost too many prints to do it all by hand. The material of the MJF print is grey PA12. And all prints are already printed and curred. I tried already using a stamp and an inkpad, but the ink doesn't seem to stick and just smudges. I cannot mechanically engrave something easily, because the material is very thin and the surface is three-dimensionaly shaped. Possible I guess, but it would be a headache to get that right. I thought about laser engraving, but from what I have read so far, it doesn't seem to work either in my case. Or ? What else is out there ?
