Here is the second project I did last week. One of my office-mates, who has generously listened to me lasering things for the last two months without complaint, asked if I would help him make some volunteer awards for a racing group he is active in. We decided to use 1/4" acrylic to give them a nice hefty feel. He then made a simple wood base for each and mounted two LED lights underneath. The lights give the awards an internal glow that really highlights the engraved areas.
This project went pretty smoothly. We had to take a couple of tries at getting the resolution right. At first I tried using a lower resolution (125 lpi) to speed the engrave time, but I found it looked a little too pixelated. We were happy with the smoother look of 195 lpi, which still let us shave a little time off of the default setting.
We were both thrilled with the results. My office mate said the awards looked better than the professionally made ones they gave to the racers. Next year maybe they should make them all with a Glowforge.
