Laser: Corporate anniversaries

The very first thing done using the laser.

Qualcomm used to give out glass blocks for employees’ 10, 15, and 20 years anniversary. But for cost-saving, recently they switched to crummy-looking plastic blocks. Having cut the previous plaque for a coworker, I think I can make something similar too, so I tried making this.

First time working with acrylic, and man, it was so much cleaner than working with wood. The way the laser cuts through a block of acrylic is like someone taking an invisible knife and cut through a piece of jelly. There is no flame, no smoke, no light, no sign that a large amount of heat is being focused on a tiny area. The plastic just simply cleanly evaporated away from the cut. It was mesmerizing to watch.

Acrylic + circuit traces = awesome. 1/4″ cast acrylic, 2 passes 12mm/s @ 13mA

Also first time working with a lasermask. It looks very nice, but it can be hard to control the laser so that it just cuts through the mask without evaporating much of the plastic underneath. I don’t think I will be using much of that mask though.

Seeing how that looked, I had another “customer” – 10 year anniversary of my mom’s company. Since we wanted something that looked more “elegant” than “cool”, we opted for 1/4″ cedar sheet this time. The stand was done impromptu, and also used the scrap cedar, and this is so far the most professional-looking piece of lasercut souvenir that I’ve made.

Third time’s a charm. 1/4″ cedar, 2 passes @ 14mm/s 13mA
