Hello Mr. Rongzhong Li, What made you favor plywood for the Nybble framework? Have you thought about PMMA (plexiglass) or PVC?
Hello,
I just did some laser cutting tests!
The PMMA (plexiglass) very pretty, nice finish possible, but very cracking, it's a shame, it could have made a beautiful Turing with leds of colors :)
After research the PVC does not cut with the laser.
What kind of "type" of materials do you use?
The Birch Plywood seems to support laser cutting.
