Laser Cutting vs CNC: Which is Right for Your Project?
When it comes to precision fabrication, laser cutting and CNC routing are two of the most popular technologies available. At Fabberz, we offer expert laser cutting services in Brooklyn and beyond — and we often get asked: “What’s the difference between laser cutting and CNC routing?” This guide breaks down the pros, cons, and ideal uses of each to help you choose the right process for your next project.
What Is Laser Cutting?
Laser cutting uses a high-powered laser beam to cut or engrave materials with extreme accuracy. It’s ideal for intricate designs, tight tolerances, and fine details.
Benefits of Laser Cutting:
Precision: Perfect for detailed cuts and delicate designs.
Speed: Cuts thin materials quickly and cleanly.
Finish: Produces smooth edges with minimal post-processing.
Material Efficiency: Minimal kerf (cut width) reduces material waste.
Great for: Acrylic, wood, paper, leather, fabrics, and certain metals.
Limitations:
Material Thickness: Not ideal for cutting thick or dense materials.
Burn Marks: Heat can cause slight discoloration or charring on some surfaces.
What Is CNC Routing?
CNC routing uses a spinning bit (like a drill) to mechanically cut material along a programmed path. It’s well-suited for larger, thicker, or more rigid materials.
Benefits of CNC Routing:
Thick Material Capability: Cuts deeper and through thicker stock than laser cutting.
3D Contouring: Can mill complex, multi-depth shapes.
No Heat Affected Zones: No burn marks or discoloration.
Great for: Wood, MDF, plywood, plastics, aluminum, foam, and composites.
Limitations:
Less Detail: Not ideal for highly intricate or delicate designs.
Slower on Small Cuts: Takes longer on fine work compared to lasers.
Higher Cost: CNC is typically a more expensive fabrication.
Tool Marks: May require sanding or finishing.
Which Should You Choose?
Choose laser cutting if: Your design involves intricate shapes, engraving, or you’re working with thin materials like acrylic, wood veneer, or paper.
Choose CNC routing if: You’re cutting thicker stock, need 3D contours, or want to work with solid wood or composites.

FAQs: Laser Cutting vs CNC Routing
Q: What’s the main difference between laser cutting and CNC routing?
A: Laser cutting uses a focused beam of light to cut or engrave materials, while CNC routing uses a spinning bit to physically remove material.
Q: Is laser cutting more precise than CNC routing?
A: Yes, laser cutting offers higher precision, tighter tolerances, and finer detail — especially for intricate patterns or delicate materials.
Q: What materials work best for laser cutting?
A: Acrylic, wood, paper, leather, textiles, and thin plastics. Some thin metals can also be laser cut depending on the wattage.
Q: What materials are best suited for CNC routing?
A: MDF, plywood, hardwoods, plastics, aluminum, foam, and thicker stock materials.
Q: What files are best for laser cutting?
A: .AI, .SVG, .DXF, or .3DM — vector-based formats are ideal for clean, scalable cuts.
Q: Can I laser cut thick materials?
A: Laser cutters are best for thin to medium materials. For thickness over 1/4" (depending on the material), CNC routing is usually more effective.
Q: Which process is faster — laser cutting or CNC routing?
A: Laser cutting is faster for thin materials and detailed work. CNC routing takes longer but is necessary for deeper cuts or 3D shapes.
Q: Will laser cutting burn or discolor my material?
A: It can, especially on wood or cardboard. Using protective masking or adjusting power/speed settings helps reduce marks.
Q: Can CNC routers engrave designs like a laser?
A: Yes, but the detail level is lower. Laser engraving is better for logos, text, or fine textures.
Q: Is laser cutting cheaper than CNC routing?
A: For small, detailed jobs and thin materials — usually yes. For large, thick, or structural projects, CNC may be more cost-effective.
