Complete Laser Cutting Guide

1. What Is Laser Cutting?

Definition:

Laser cutting is a manufacturing process that uses a high-power laser beam to cut, engrave, or mark materials with extreme precision. The laser melts, burns, or vaporizes the material following a pre-programmed digital design.

Types of Laser Technology

CO₂ Laser

  • Uses carbon dioxide gas
  • Power: 30W – 400W+ (typically 60–150W for commercial use)
  • Ideal for: Wood, acrylic, leather, fabric, paper, cardboard, rubber, glass (engraving)
  • Not suitable for: Metals (except engraving with additives)
  • Most common and versatile for general applications

Fiber Laser

  • Uses a fiber optic laser source
  • Power: 20W – 6000W+
  • Ideal for: Metals (steel, aluminum, copper, brass, titanium)
  • Also cuts: Some plastics
  • Faster and more efficient for metals

Diode Laser

  • Uses semiconductor diodes
  • Power: 5W – 40W
  • Ideal for: Engraving on wood, leather, paper
  • Limitations: Slower speed, cannot cut thick materials
  • Common in low-cost desktop machines

Advantages of Laser Cutting

  • ✅ Extreme precision: Tolerances of ±0.1 mm or better
  • ✅ Clean edges: Minimal post-processing required
  • ✅ Complex designs: Can create intricate details impossible with traditional methods
  • ✅ Non-contact: No tool wear, no material deformation
  • ✅ Versatility: Multiple materials and thicknesses
  • ✅ Repeatability: Identical results in mass production
  • ✅ Speed: Much faster than manual or traditional cutting
  • ✅ No molds: No need for expensive tooling for prototypes or short runs

2. Materials That Can Be Laser Cut

Wood and Wood Products

Plywood

  • Common thicknesses: 3 mm, 6 mm, 9 mm, 12 mm

3. Design File Preparation

Accepted File Formats

Vector Formats (Preferred for Cutting)

  • .AI (Adobe Illustrator) – Most common
  • .DXF / .DWG (AutoCAD) – For technical design
  • .SVG (Scalable Vector Graphics) – Universal, open standard
  • .EPS (Encapsulated PostScript)
  • .PDF (with vectors, not rasterized)

Raster Formats (For Engraving Only)

  • .JPG / .JPEG
  • .PNG
  • .BMP
  • .TIFF

Minimum resolution: 300 DPI for best results

Design Software

Professional Software

  • Adobe Illustrator – Industry standard
  • CorelDRAW – Popular in the sign-making industry
  • AutoCAD – For technical/mechanical design
  • SolidWorks / Fusion 360 – 3D design that exports to 2D

Free Software

  • Inkscape – Free alternative to Illustrator
  • LibreCAD – Free 2D CAD
  • QCAD – Open-source 2D CAD

Critical Rules for File Preparation

1. Cut Lines vs. Engraving Lines

  • Cut lines: Vectors with very thin line weight (0.001″ or “hairline”)
  • Engraving lines: Regular vector strokes or filled areas
  • Use different colors to distinguish operations:
    • Red = cut
    • Black = engrave (common convention)

2. Units and Scale

  • Verify that dimensions are in the correct units (mm, cm, inches)
  • Design must be at full 1:1 scale
  • Include key dimensions in a separate layer for reference

3. Kerf (Cut Width)

  • The laser removes material (typically 0.1–0.3 mm)
  • For assemblies: Adjust slot/tab dimensions to account for kerf
  • For precise parts: Run test cuts to measure exact kerf

4. Design Optimization

Minimum Spacing:

  • Between cut lines: At least 1–2 mm
  • For small details: Minimum width of 1 mm
  • Avoid very thin geometries that can easily break

Simplification:

  • Simplify vector paths to reduce cutting time
  • Remove unnecessary nodes
  • Join open paths to create continuous shapes

Nesting:

  • Arrange pieces efficiently to minimize material waste
  • Leave 3–5 mm between pieces
  • Orient wood grain appropriately

5. Text and Typography

  • Convert all text to outlines/curves (outline/expand)
  • Minimum text size: 10–12 pt for cutting, 8 pt for engraving
  • Avoid ultra-thin fonts or very fine details
  • Sans-serif fonts work better than serif fonts for small cuts

6. File Review

  • Duplicate lines: Remove them to avoid double cutting
  • Open paths: Close them so shapes are complete
  • Groups: Ungroup everything before sending
  • Hidden layers: Remove or ensure all required elements are visible

Checklist Before Sending:

  • ✅ File in vector format (.AI, .DXF, .SVG)
  • ✅ Cut lines set to “hairline” or specified thin stroke
  • ✅ Colors properly assigned (cut vs. engrave)
  • ✅ Dimensions verified at full scale
  • ✅ Text converted to outlines
  • ✅ No duplicate lines
  • ✅ All paths closed
  • ✅ Pieces nested efficiently (if applicable)
  • ✅ Notes included for desired material and thickness
