I was curious, what can I cut with a 9 watt blue laser diode?

cardboard if it is relatively thin

Sweet. I am ok waiting. I have been working with 3d printers and some of my prints were 15hours. Can I cut thin plywood too? Like 1/4inch? Will require multiple passes I guess, so you don’t light it on fire.

Thanks. Now, to make a heatsink for it. Any suggestions? Water cooled, or aluminum fins with a fan?

So major good water cooling.
