Create two layers in a vector tool. I use Affinity Designer. The "back" shape needs to be the filled in outline of the more complicated "front" shape.
Sometimes with clever planning, you can squeeze more cuts out of a single sheet of wood.
I'm cutting 1/4" Cherry plywood on a Glowforge. I use a strong cut (125/50) to ensure full separation.
Obviously, you need the same number of "backs" and "fronts".
The front shape should fit perfectly, and not overhang or underhang anywhere. Thanks, laser cutter!
Spray the backs with adhesive glue, and set the fronts in place. Let dry 1-2h.
Plan your color scheme, mix your resin, color it, draw it into a syringe, then carefully fill the sections of the art.
Use a heat gun to draw any bubbles to the top. Then let the pieces dry for 24h.
I'm working on a new creative workflow to make colorful "laser shapes" using wood and resin. I have the creation process documented above, check back tomorrow for the finished results!
