I'm not an expert of 3d printing.
But... t I need to reproduce some small objects like ancient coins to make plastic replicas.
I attach an example of coin to make understand the resolution and the kind of replicas that I need to produce.
I've tried to create the .stl file from that .jpg or .bmp and I've found the best solution with Bmp2cnc, but I need to join the 2 images to make an unic product. I don't need to stamp the 2 sides, but to join them.
Also if you have other solutions please tell me.
As I have to create really a lot of replicas I don't need a modeler who can create all the .stl for me, but I need someone how can explain me which is the process to follow to have a 3d plastic replica from this kind of images, creating also some examples.
