I submitted a simple design for 2D-3D production that was rejected. It is intended for a lapel pin or a brosche.
The engraved part in the center - which is a repetition of the main design - apparently cannot be printed.
See image attached:
Dimensions: cm: 2.882 w x 2.882 d x 0.198 h
"The file contains shells which aren't attached correctly, printing it will result in them not being attached and getting lost in the printing process. Please overlap the parts so they will bee seen as one."
I would like to print this in plastic - alumide - and in metal such as silver or bronze.
Can someone tell me how to correct this - suggest the right software - or do it for me?
