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.
