Is CNC Cheaper Than Laser? – CNC Machining vs. Laser Cutting

Regarding subtractive manufacturing, CNC and Laser cutters are two of the main cutting methods most popularly employed in the industry.

If you are unaware of the intricacies of manufacturing and cutting methods, you may be at a loss for knowledge.

These two manufacturing methods are becoming a vital part of work for many individuals in the industry, and therefore, we have curated this article to make this easier for you.

Let’s discuss the basics of each method and how they vary in pricing. After that, we will share why each is better than the other in each aspect specifically, so let’s begin.

Comparison of CNC Machining and Laser Cutting

Before we go into details, you need to understand what these processes are in terms of definition and their purpose. Then we will see how they differ.

What is a CNC Machine?

A CNC machine or router is a cutting machine that the operator can control through a computer or program with a hand-held router mounted as a spindle.

The machine uses the spindle to cut through different materials when passing through or around a material through friction.

As the machine is controlled through a computer program or Computer Numeric Control, it is named CNC.

What is Laser Cutting Machine?

If you are using an intense laser beam to do your cutting, or in some cases, engraving different materials, then you are using a Laser cutting machine.

The light, in this case, is amplified by radiation or emission through optics. Laser is the abbreviation of Light Amplification by Stimulated Emission of Radiation.

Laser-cutting machines are also controlled by computer programs such as CNC machines.

Overview of the Differences Between CNC Machining and Laser Cutting

In summary, their main difference is how these machines use their tools to make the cutting.

CNC uses tools and bits that are sharp as required to cut, but it happens through friction.

On the other hand, Laser cutting utilizes a hot fiery laser beam that does all the cutting that is fired at the job part.

Because of these significant differences, both scenarios shine over the other at specific work and tasks.

Analysis of the Cost-Effectiveness of CNC Machining and Laser Cutting

Following are some typical scenarios where the cost plays a significant factor in choosing one machine over the other or between the sizes of these machines.

Initial Investment

You need to consider machine prices, the tax incurred, customs and shipping rates, etc., to break even and make a profit; you need as much minimum initial investment as possible.

Overall, based on your requirements, you have a lot of room to play between $200 – $150k though industrial CNC machines are on par with laser cutters regarding accuracy and speed.

Both machines have a similar price range; the primary difference comes in operation costs and how you maintain them.

Operation Costs

The primary cost of machine cutting is the electricity costs calculated in units consumed during each job’s duration and parts or tools’ life.

You need to factor this into the price of the product you are selling and the profit you need to make.

Laser machines have quicker cycle time than CNC machines, reducing the per unit cost of electricity for the same job.

They have smaller and lesser parts involved which further reduces the operational costs.

But when you need to change the laser source, it is a considerable cost incurred during the machine’s lifetime, which can be between 5-15% of the machine’s actual cost.

Size and Footprint

Based on your working floor or area, you must consider how much the machine will cover and how much room is left for other purposes.

Factor in the gantry or other related attachments into the machine’s footprint.

Laser machines eliminate this factor by using a galvanometer laser head, making them more portable.

For small workshops and smaller jobs, the laser cutter is more economical.

Manufacturing Tools

The tools and bits for both machines are factored in on the overall cost of your operation.

Though you can start with a few bits or a single-tool of laser cutter with varying power and speed, you can enhance your repertoire when making money.

CNC Machines have more variety and flexibility regarding a massive assortment of bits and tools, which may increase initial cost.

In the case of laser, you can adjust power and speed in laser, but if you need a more powerful laser for more variety, the cost is almost the same as a slew of tools and bits for CNC.


The working material waste can lodge into internal parts of the CNC machine, which may cause cost overheads during the machine’s lifetime and will need frequent cleaning and greasing, increasing cost.

Furthermore, wear and tear of the spindle is a considerable cost incurred periodically.

The laser cutter has mostly a one-time cost; after that, it mostly requires cleaning, so fewer maintenance costs than CNC.

When to Choose CNC Machining Over Laser Cutting?

Advantages of Laser Cutting in These Situations

  • Laser machines have lesser parts and take longer to replace the optical system.
  • It requires minimal waste cleaning as there is lesser machining and lower wastage.
  • No parts have wear and tear, for example, the spindle.
  • The spindle causes high working noise even at low load settings where laser noise suits residential areas.
  • Typically, CNC needs about 0.004” tolerance between adjacent cuts, which is far less for the laser, around 0.0004”.
  • As the CNC machine works from friction, it needs stronger material for the belt and movement mechanism, costing more. In contrast, a Laser cutter can easily hold the material with less clamping force.
  • The major pros of CNC machine cutting are that it can easily make a 3D carving of any material because of the easy and simple combination of all three axes with increased cut depth.

CNC Machining vs. Laser Cutting: Costs and Implications

Finally, we will discuss some implications of both machines regarding cost.

Summary of the Cost Comparison Between CNC Machining and Laser Cutting

The price and age of CNC cutting make it more viable in the industry, where laser cutting is more costly, especially during processing.

The operational costs are higher due to higher electrical unit consumption. If cost is not an issue and more precision and consistency are required, then the Laser cutter seems more viable as you get more control.

Implications for Businesses

As we said, CNC machines are more viable for small to large-sized industries because of how long they have been used.

Furthermore, if you want to work on bigger parts, businesses should choose CNC machines over Laser cutters or if you are looking for curved, diagonal, or straight line cuts. These are not easily achievable with laser cutters.

Regarding smaller parts, engravings, or industries short on space, Laser cutters are far superior in working than CNC machines.

Future Prospects of CNC Machining and Laser Cutting in Manufacturing

The future of CNC machining looks promising because of advancements in science providing more precision tools and techniques.

Furthermore, more complicated sensors and control systems can help companies produce more accurate machined parts and enhance tolerances.
