The difference between CNC cutting & laser cutting
There are a lot of similarities between CNC machines and laser cutters. They both use a reductive fabrication process to help cut or engrave materials to your desired shape and size. That said, there are quite a few significant differences in how they run and what kind of projects each tool is best suited too.

When to use the CNC or the laser cutter
What’s the difference between a CNC machine and a laser cutter?
The biggest difference between a CNC machine and a laser cutter comes down to the tool they use to do the cutting. CNC cutting is achieved through friction; they use tools and bits to route into the material. In contrast, laser cutting happens through fiery hot laser beams being fired at a material.
It’s a critical difference and it means that each type of machine has its own scenarios where it really shines.
What is a CNC machine?
A CNC router is a computer-controlled cutting machine which mounts a hand-held router as a spindle, then uses that to cut through materials using physical contact. CNC machines are automated and follow a set programmed path through computer numerical control (that’s where the CNC comes from).
What is a laser cutter?
A laser cutter is a machine that uses the power of an intense laser beam to cut or engrave a multitude of materials intricately. Instead of cutting using physical contact and abrasion with a tool, the light beam does all the work in laser cutting.

What is the difference between CNC and laser cutting?
The difference between the processes of CNC machining and laser cutting comes down to how the cutting actually occurs. Instead of a cutting tool, a laser relies on heat to cut or engrave the product. While CNC cutting carves out the design using a tool similar to what you might do by hand (but way more effectively and efficiently), laser cutting relies on a high-energy laser that burns through the material.
What are the advantages of a CNC?
CNC machining is way more precise than manual machining and can be repeated in exactly the same manner again and again. They are great for increasing production speed and efficiency.
Compared to laser cutting, CNC machines are often quite a bit larger, so they’re very helpful for large-scale installations and projects. For hardwoods and dense materials, they are also more effective at cutting and shaping, and can cut some materials that are dangerous to fire a laser at.
What are the disadvantages of a CNC?
Compared to laser cutters, CNC machines are not as effective at intricate designs, and can be cost-prohibitive to use because of their scale of overhead. For detailed pieces like event decor, signage, or thin plywood projects, a laser cutter is often the better choice for speed, accuracy and cost-effectiveness.
Do I need a laser cutter or a CNC for my project?
Conveniently, at Larrikin, we’re lucky to have not only our large laser cutter, but we also have access to a full-suite of in-house fabrication services including two 3-axis CNC milling machines and a full workshop (through our lovely parent company and companions at CNC Cutting Inc.)
That means we can help you realize projects of any size or scope, from the grandiose to the infinitesimally small. If you’re not sure whether you need a CNC or a laser (or perhaps both to finish the full scope of your project), give us a shout and we’ll help you out on every front.
