This is a Key Smart pocket knife style key ring that I have etched with my phone number and a checker-plate steel design.
Laser fill of paths produced by Illustrator.
This was a test of anodised aluminium, but also me figuring out how to align small objects on the laser bed.
I am super impressed by the results. The detail is incredible.
The Stainless Steel screw heads are definitely etched - Not black, but I can’t scratch it off…
The keys were left un-marked.
Here’s the LASER FILL settings on the Emblaser 2.
Note the narrow line distance.
It took my little Notebook PC about 6 minutes to crunch the Gcode for this.
I wish laserweb’s processing percentage scale thing was more accurate instead of doing nothing for 6 minutes and then being ready.
The anodising can etch off much faster (600mm/min or more), but I didn’t want to lose detail by shaking things around too much.
