Laser Cutter Power Calculator

How It Works

Laser cutting success depends on balancing speed, power, and material properties. Too fast = incomplete cuts; too slow = charring, melting, or fire risk. Always do a test cut on scrap material first. Air assist (compressed air blown at the cutting point) is essential for cutting — it removes debris, prevents flame-ups, and keeps the lens clean. For engraving, lower power and higher speed produce fine detail. Acrylic gives the cleanest laser cuts with polished edges. Plywood and MDF can char at the edges — masking tape on the surface reduces smoke staining. Never laser cut PVC, vinyl, or polycarbonate — they release toxic chlorine gas. Always ensure proper ventilation or fume extraction when laser cutting any material.
