Are you looking to invest in a CNC or laser cutter? Perhaps you’re ready to take your project from the concept phase to the final product. If this is the case, then you’ve come to the right place.
In this article, we’ll be going over the differences between CNC vs laser cutters to help you determine which is best for your cutting task.
So if you’re ready to discover which type of 3D cutting machine is best suited for your needs, then keep reading. You might not exactly know what each does but you know you need them. Let’s begin!
Comparing CNC and Laser Cutter Technologies
CNC and laser cutting technology are both used to cut or shape a variety of materials. But there are key differences between these two that should be noted.
CNC machines are automated, meaning that they can be programmed to cut out materials with accuracy and repeatability. They have a wider range of applications due to the flexibility of being able to be programmed to cut multiple shapes
On the other hand, laser cutters are more appropriate for softer materials such as fabrics, paper, and foam. They can also be used to cut intricate shapes with higher speed and accuracy than a CNC machine.
However, the materials that can be cut with a laser cutter are limited. Lastly, they are often faster than CNC machines, as they don’t require the hardware setup time for machines.
Different Types of Laser Cutters
Laser cutters are commonly used in a range of industries for cutting and processing a variety of materials. Depending on the application, there are many types of laser cutters available.
CO2 Laser Cutters
CO2 laser cutters are among the most common type and offer formidable performance and tremendous versatility. They are used for cutting thicker materials such as wood, acrylic, metal, and even titanium and stainless steel.
In addition, they allow for high speed and high accuracy when cutting and engraving. Lastly, they can also be used to etch and mark delicate materials like glass and ceramics.
Fiber Laser Cutters
These robust cutting systems are perfect for use in a wide variety of industries. They are available in various sizes and configurations, including traditional tubes, flatbeds, and hand-held.
They are designed to reduce power consumption and noise levels while maintaining precision and speed. Finally, it can handle many materials, offering superior cutting power for both large and small-scale applications.
Sublimation Laser Cutters
Sublimation laser cutters are often used in small businesses such as graphic design studios or fabric shops. They are often used to create images and text to be sublimated onto apparel and materials.
These types of cutters can be especially helpful when making fine logos and text on materials with intricate curves or flourishes. Sublimation laser cutters are great for applications such as:
- cutting fabrics for garments
- die-cutting thick paper for business cards
- cutting intricate designs out of wood or vinyl
Lastly, have the ability to cut with pinpoint accuracy, which maximizes cutting efficiency and minimizes waste.
Ultrashort Laser Cutters
Ultrashort laser cutters use very short pulses of light to create high-quality cuts that are precise and fast. It vaporizes the cutting material more quickly and effectively, allowing for faster production times and higher accuracies.
The pulse length and energy of these cutters can be adjusted to control how much material is removed per cut. This makes them highly customizable for a variety of products and thicknesses.
It is most common in industrial settings and can be used to cut materials such as metal, carbon fiber, wood, glass, cardboard, and leather.
How Much Does Each Type of Cutting Machine Cost?
CNC and laser cutters are both powerful tools for cutting materials into detailed shapes and sizes. They each have their respective strengths and weaknesses, as well as varying price points.
CNC machines are more cost-effective since they can make hundreds of cuts with a single setup. Additionally, it can be operated in many locations, allowing for a degree of flexibility that laser cutters simply cannot offer.
On the other hand, laser cutters require more accuracy and can cut materials at much higher speeds than CNC machines. However, they are more expensive to purchase and run since they require specialized equipment and knowledge to operate.
Key Differences in Features
CNC machines utilize physical cutters like milling cutters and drill bits. They have cutters moving in three dimensions at different angles and speeds to shape materials like wood, metals, and plastics.
Laser cutters, on the other hand, use high-powered lasers to vaporize material in two-dimensional shapes and can cut through materials like glass, wood, and acrylic plastics. They can also process up to 10 times faster than CNC machines.
Additionally, the cutting accuracy can reach as low as 0.2mm versus CNC machines, which can only cut roughly in the range of 1-2mm. Ultimately, they require less maintenance and have a longer lifespan that can last over 50,000 hours before needing to be replaced.
In-Depth Look at Machine Performance and Efficiency
The efficiency and productivity of a CNC machine is much higher than a laser cutter. CNC machines can easily cut a variety of materials, and when programmed correctly, they can cut components more quickly than a laser cutter.
On the other hand, laser cutters take much longer due to the intensity of the laser and the optics required to focus on the material. Yet, they allow for much more precise cuts due to the high-level accuracy of the beam.
Overall, both technologies provide a high level of accuracy and performance, but CNC machines have the edge in productivity and total performance.

A Guide to the Differences Between CNC vs Laser Cutter
CNC vs laser cutter has its advantages and disadvantages. CNC is ideal for creating fine details on a 3D sculpted object, whereas laser is great for cutting out bulk material.
Ultimately, the decision of which technology to use depends on your specific needs. To get a better feel for which option is best for you, it’s best to contact a professional to discuss your business needs.
