Best Materials for CO₂ Laser Cutting and Engraving
Best Materials for CO₂ Laser Cutting and Engraving
Choosing the Right Material for Professional Results
Not every material reacts the same way to a laser beam. Some cut cleanly with perfect edges, while others burn, melt, or release unsafe fumes. Knowing which materials work best with CO₂ laser systems ensures precision, consistency, and safety—whether you’re creating signage, prototypes, or production components.
Top Materials for Laser Cutting
Acrylic (Cast and Extruded)
Cuts: Cleanly with flame-polished edges
Engraves: Smoothly with sharp contrast
Applications: Signage, awards, retail displays, lighting panels
Tip: Cast acrylic engraves better than extruded for crisp detail
Birch and Other Plywoods
Cuts: Cleanly with some edge darkening
Engraves: With excellent tonal range
Applications: Models, decor, product packaging, art pieces
Tip: Choose high-quality laser-safe ply—cheap alternatives may contain glue layers that burn inconsistently.
Hardwoods
Cuts: More slowly but with rich color and depth
Engraves: Dark, textured marks with high contrast
Applications: Custom furniture parts, signage, craft goods
Tip: Consistency varies by grain density—test before large runs.
Paperboard and Cardstock
Cuts: Quickly and accurately with minimal burn
Engraves: Subtly, perfect for pattern work
Applications: Packaging, stencils, invitations, prototypes
Tip: Use air assist to prevent edge scorching.
Leather (Genuine or Laser-Safe Synthetic)
Cuts: Cleanly with sealed edges
Engraves: With dark, high-contrast surface markings
Applications: Branding, accessories, signage, decor
Tip: Only cut verified laser-safe synthetics—PVC or vinyl-based materials are unsafe.
Delrin (Acetal)
Cuts: With smooth, durable edges
Engraves: Precisely without residue
Applications: Mechanical parts, jigs, and gaskets
Tip: Emits a mild odor when cut—use proper ventilation.
Materials to Avoid
Some materials release toxic fumes or damage the machine:
PVC and Vinyl: Produce corrosive chlorine gas
Polycarbonate: Discolors, melts, and emits harmful smoke
ABS Plastic: Melts and gives off cyanide gas
Fiberglass: Burns unpredictably and ruins optics
If unsure, always confirm your material’s safety with a technician before cutting.
