The following table highlights the main differences between CNC routers and laser cutters.
| Feature | CNC Router | Laser Cutter |
|---|---|---|
| Cutting Method | Spinning bit removes material by contact | Focused light beam vaporizes or melts material without contact |
| Material Thickness | Up to several inches | Typically less than 0.5 in (12 mm), some models cut up to 1 in |
| Material Range | Wood, plastics, foams, soft metals | Wood, acrylic, fabric, paper; some high-power models cut metals |
| Cut Quality | May require sanding or finishing | Clean edges, often no finishing needed |
| Precision | Around 0.1 mm to 0.2 mm | Under 0.1 mm consistently |
| Kerf Width | 1 mm or more depending on bit size | 0.1–0.3 mm |
| Speed | Faster on thick or 3D cuts | Faster on thin, flat parts |
| Operating Noise | Loud | Quiet |
| Waste | Moderate sawdust and chips | Minimal dust; tight nesting reduces waste |
| Maintenance | Bit replacement; lubrication of moving parts | Tube replacement; lens cleaning |
| Learning Curve | Steeper (tool selection, speed and feed settings) | Gentler (focus and power settings) |
| Dust/Fume Control | Requires dust collection | Requires fume extraction and filtration |
| Initial Cost Range | $5,000 to $50,000+ | $3,000 to $30,000+ |
| Energy Use | Lower power draw; electric motors | Higher power draw; laser tube |
