CNC Routing vs. Laser Engraving: Which One Do You Need?

We get this question a lot: “Do I need CNC or laser?” The answer depends on your material, the level of detail you need, and how thick the material is.

Here’s a straightforward comparison based on the work we do every day.

Laser Engraving: Fine Detail and Thin Materials

A laser uses a focused beam of light to burn, score, or cut material. It excels at:

• Sharp inside corners — unlike a CNC router bit (which is round), a laser can make perfectly sharp 90-degree corners
• Fine text and logos — great for branded items, awards, and detailed patterns
• Thin materials — cuts through material up to about 1/8 inch thick
• Surface engraving — burns images, text, or patterns into the surface without cutting through
• Water bottles and coated items — the laser burns off the coating to reveal the metal underneath

Our laser cutting surface is 12 by 24 inches. We also have access to a larger 4 by 8 foot laser for bigger jobs.

CNC Routing: Thick Materials and Large Pieces

A CNC router uses a spinning bit to cut and carve material. It’s better for:

• Thick materials — handles material up to 10 inches thick
• Large pieces — our big machine does 5 by 10 foot sheets
• 3D carving — creates dimensional shapes like sink forms, banisters, and furniture legs
• Production runs — cuts hundreds of identical pieces with repeatable precision
• Structural parts — cabinet components, countertops, set pieces that need to bear weight

When You Need Both

Some of our best projects use both processes:

• Signage: CNC routes the overall shape, laser engraves the fine text and logo detail
• Branded products: CNC cuts the form, laser adds the personalization
• Art pieces: CNC creates the layered structure, laser adds surface detail
