I’m Sunny. I’m new here. I didn’t know such an active laser engraving community existed until now! I own a 60W fiber laser engraving machine and had it for months now, but still lack a lot of laser knowledge. Apologies in advance!
I have been wanting to create 2.5D portrait coins for months now like the photo attached. My question is, does anyone have any idea if something like this is possible with laser? Or is this only possible with a CNC machine?
The photo is engraved on a 20mm diameter silver sterling coin with 2mm thickness. I’m not sure about the face depth, but it doesn’t seem that deep.
I tried engraving jpegs and hired a few 3d model designers to create STL files, but the results would just not come close to what I’m aiming for. Jpegs are flat and STL files look slightly different from the photos and don’t have enough detail because it’s basically digitally sculpted.
I’m just so amazed by the attached photo because it’s like an exact copy of the photo with all the details, but at the same time is 2.5D (not flat) with shadows and everything. It contains so much detail when the face depth doesn’t seem that deep.
Any help or guidance would be extremely appreciated!
