Laser Cutting vs CNC Routing: What’s the Difference and When to Use Each?
🛠️ Introduction
You need a part cut—maybe a bracket, sign, screen or panel. But you're not sure if you need laser cutting or CNC routing.
While both processes can cut shapes from flat materials, they’re not the same—and using the wrong one could mean slower turnaround, higher cost, or poor results.
Here’s a breakdown of laser cutting vs CNC routing—and how to decide which is best for your next project.
🔍 What Is Laser Cutting?
Laser cutting uses a high-powered laser beam to melt, burn, or vaporise materials with extreme precision. It’s ideal for:
Metal (mild steel, stainless, aluminium)
Fine detail and sharp internal corners
Projects requiring tight tolerances
At Metalmorphic Laser, our machines cut metal cleanly and quickly—with minimal finishing required.
🪚 What Is CNC Routing?
CNC routers use a rotating cutting tool (bit) to carve out shapes from materials by physically removing material through friction. Best for:
Wood, plastic, and soft composites
Jobs where edge burn is undesirable
Thicker or layered materials (like MDF)
CNC routing is common for cabinetry, woodworking, and signage—but it’s slower and less precise than laser for metal.
🆚 Key Differences at a Glance
Laser Cutting
Cutting Method - Focused light/heat
Material Types - Best for metal, acrylic, thin wood
Edge Finish - Clean, sharp, minimal finishing
Detail Level - High precision, small radii possible
Speed - Fast and clean on metal
CNC Routing
Cutting Method - Spinning mechanical tool
Material Types - Best for wood, foam, soft plastics
Edge Finish - May require sanding or tool cleanup
Detail Level - Limited by tool diameter
Speed - Slower, especially on dense material
🤔 When Should You Use Laser Cutting?
Choose laser cutting when you need:
Clean, accurate cuts in metal
Detailed internal shapes (sharp corners, small holes)
Minimal cleanup or secondary processes
Speed and consistency in repeat jobs
Perfect for brackets, plates, panels, signage, and structural components.
🤔 When Should You Use CNC Routing?
Choose CNC routing when:
You’re cutting timber, MDF, foam, or plastic
You need deep carving or engraving into soft materials
Sharp internal corners aren’t essential
You’re doing large signage with layered designs
We don’t offer CNC routing in-house—but we’re happy to refer you to trusted local partners if your job is better suited to that process.
💬 Still Unsure?
We’re happy to review your file, sketch, or idea and recommend the best process—even if that means referring you elsewhere. No obligation, no confusion—just honest advice.
