Laser Cutter Power Setting Calculator
Determine safe power settings based on material thickness and travel speed.
Thickness of material to be cut
Desired laser head travel speed
Power ≈ Thickness * Speed * Constant
3mm wood at 15mm/s suggests approximately 80W power.
Does laser power vary by material?
Yes, denser materials require more power. Acrylic, wood, and paper all require specific power/speed profiles.
Risk of too much power?
Too much power can burn material, widen the kerf, or lead to charring rather than a clean cut.
What is cutting speed?
Speed is how fast the laser head traverses the path. A balance between speed and power determines the cut quality.
