Laser Cutter + Acid Etching
I tried the technique to paint, laser etch off, and acid etch brass to create dimensional designs that can’t be replicated using traditional methods. As a first attempt, I designed a retro machine tag. CNC’d the brass blank, painted, and lasered the design, then acid etched and repainted the badge. Here’s the results.
SLA Cold Casting
With the high-detail of SLA printers, I wanted to cast from it. But, why just cast another piece of plastic when you could cast it in metal? Well, I can’t exactly light up a foundry inside, so I tried the Cold Casting method. I mixed 50% brass powder with 50% resin, and this is what I got. Add a little shoe polish, and burnish with a spoon, and you get a pretty convincing result.
