Frequently Asked Questions

Can you laser engrave on plastic?

Yes β€” many plastics engrave beautifully with lasers. Acrylic, ABS, PETG, polycarbonate, and laminate plastics engrave cleanly and are commonly used for signage, tags, and control panels. The correct laser type and airflow prevent melting and discoloration.

What laser setting is best for plastic engraving?

Plastic engraving requires high speed and moderate power to avoid heat buildup. Typical starting ranges:

  • Diode: 20–60% power, high speed
  • CO2: 10–40% power, medium-high speed

Air assist is critical for edge clarity and surface finish.

What plastics cannot be laser cut?

Never laser cut:

  • PVC or vinyl (produces toxic chlorine gas)
  • Polyurethane foam
  • Teflon (PTFE)
  • Fiberglass-reinforced plastics

These materials are unsafe and can damage both your machine and your health.

Do I need a 10W or 20W laser engraver for plastic?

Both work well. A 10W diode handles light engraving and thin plastic sheets, while a 20W diode provides faster speeds, deeper engraving, and cleaner cuts, making it better for small business production and plastic sign workflows.

What will a 100W CO2 laser cut in plastic?

A 100W COβ‚‚ laser can cut thick acrylic sheets (up to 15–20 mm), layered plastics, signage laminates, and dense engineering plastics quickly and cleanly β€” making it ideal for high-volume sign shops and fabrication workflows.

Is laser engraving permanent on plastic?

Yes β€” laser engraving permanently alters the plastic surface and will not fade, peel, or wash off, making it perfect for tags, safety labels, and outdoor signage.

Why does plastic sometimes melt when engraved?

Plastic melts when too much heat is applied. Using higher speed, lower power, proper air assist, and correct focus prevents melting and ensures crisp engraved results.
