The perfect depth, machine power level and feed speed all depend on the thickness and type of material being cut. So check and then double-check what you’re laser cutting to avoid lens, laser or health-related problems. Yet Acrylic – which looks, smells, feels and tastes just like Lexan – cuts smoothly and cleanly and is one of the best materials to use with the laser. Not to mention the fact that the fumes are hazardous to your health and that of people nearby. It is not always obviously apparent as to which materials will work – for example, both Polycarbonate/Lexan produce flames and lethal chlorine gas which will rapidly corrode your machine into uselessness. Therefore, for your own safety it’s vital that you check this list of approved and not so approved materials before attempting to laser cut stuff you’ve never worked with before. While other materials can be extremely hazardous to either humans or the machine itself (like PVC and ABS). There are a whole host of materials that a CO2 laser cutter can cut, etch or mark – but some – due to the material surface reflection – just won’t work (aluminum is an example).
