I have a 50W laser and I have cut 8mm thick balsa a few times. If you use proper speed and power it can be done without burning. It's softwood and it's very easy to cut with a laser. Actually you can cut 8mm thick balsa faster that 3mm thick MDF.
I wish I could cut 12mm thick pine with the same speed as balsa. Although pine and balsa both have the same speed and power settings on my VersaLaser machine they are completely different. |
