Not having any knowledge/experience with a laser cutter, I have to wonder, if it goes through wood by burning will it have enough power to go through plastic? Also to be considered:
How smooth will the edges be?
Is the power variable?
Will some sanding be needed if something melts?
How much movability control will you have?
Will the trans-phase inducer hold up?
If cutting plastic, will it matter if you try cutting through the shinny side if you have one. You don't want laser light bouncing off a shinny surface
And one of the most important questions....
What's the flight duration of a sparrow carrying a one pound coconut?
