Due to its high precision and accuracy, the laser has proved to be the greatest alternate of all other technologies. Laser cutting machines are super-fast and they get the job done in the most finished way possible.
Laser cutting machines are the focus of this discussion on lasers, which is a broad topic. Bear with us as we brief you about what this intelligent technology is.
Laser cutting machines use a laser to cut materials and create designs. The laser beam that is used in such machines is capable of melting, burning, or vaporizing the material.
Laser cutting is a fabrication process. It consists of an extremely thin, invisible but focused laser beam that cuts and engraves the substrate material. It can be used to cut material or create logos, patterns, designs, and write text or numbers.
The latter information is made using the engraving option of the laser cutting machines. Laser is ideal for working on metal, wood, glass, ceramics, paper, and stones. While other cutting machines are strictly dependent on one substrate material, the laser has a wide range of applications.
Laser cutting technology is widely used across various fields, including electronics, medicine, defense, automotive, healthcare, and design. Its most prominent application is in metal cutting, where it can precisely cut materials like steel, aluminum, tungsten, brass, nickel, and iron with unmatched accuracy.
A notable application is in surgical wards, where lasers are replacing traditional scalpels to vaporize human tissues and cells. This technology is used in high-risk operations, such as retina adjustment surgeries, helping patients regain eyesight lost due to accidents or aging, often restoring their vision to its original state.
Before exploring the types of laser cutting and engraving machines, it&#;s important to differentiate marking from engraving:
Laser cutting machines are differentiated based on the types of lasers being used. Consequently, the type of laser determines the type of substrate and thickness of the material.
The three main types of laser cutters are as follows:
CO2 laser cutting machines consist of CO2 gas along with a mixture of other gases like helium and nitrogen. This type of gas mixture is charged up by electric discharge which then produces the laser beam. The wavelength of such cutters is 10.6mm.
CO2 laser cutters are the most common and well-reputed because of their efficiency and cheaper prices.
Materials: Glass, plastics, leather, wood, and acrylic.
Crystal laser cutters generate beams from Neodymium doped yttrium ortho vanadate. The wavelengths of these cutters are smaller as compared to CO2 laser cutters hence they can cut through some thicker materials.
Smaller wavelength also contributes to better focus and higher intensity as well. One drawback of these cutters is that their parts wear out because of the high power functionality.
Materials: Plastics, Metals, and Ceramics.
The origin of fiber laser is seed laser which is amplified and magnified using special optical fibers. The more common name for fiber laser cutters is a solid-state laser.
The remarkable benefits of this laser cutter include cutting of reflective and conductive metals, thrice the times of efficiency as compared to CO2 laser cutters, and the absence of movable parts.
Fiber lasers can work on metals as well as organic materials. Although fiber laser cutters are very similar to crystal lasers they are more efficient and low maintenance.
Materials: Metals and Organic materials.

So, if you plan to have one for your business, you must set the priorities according to the business outline.
Here are some tips for you to choose the right one-
So, you should consider all the facts intensively before choosing the right one.
The operating costs and ROI (return on investment) vary according to the cutting technologies.
Flame-cutting technology is versatile and can cut a diverse range of metals. However, the operating cost of a flame cutter is relatively high because of the fuel gas. The flame cutter mainly functions through fuel and provides an accurate and profitable outcome.
On the other hand, laser cutter machines offer low operating costs. Also, the efficiency level is quite admirable, and this process promotes less energy consumption. For a single laser cutter, a good ROI is roughly 30%. That means the machine can deliver high-quality cuts with minimal downtime.
In another picture, a 10% annual ROI is acceptable for a large factory dealing with multiple laser cutters.
The laser cutting technology mainly operates in two processes. One is Fusion laser cutting, and the other is Vaporised laser cutting. Let&#;s see how these two processes work-
Fusion laser cutting, aka melt cutting, is one of the standard laser cutting processes. A strong laser beam focuses on a specific area of the metal. This laser beam melts the particular area and creates a fine cut in the metal.
The process starts with a high-intensity laser beam generating high power and heat. This heat focuses on a specific area steadily until the metal of that area melts. During the process, the laser beam needs to be in farm mode until the melting starts.
This helps to create a fine cut with a smooth edge. It is an effective method to cut metal with high precision within the shortest time.
Vaporization laser cutting is another laser-cutting process. This process is also known as Laser Sublimation Cutting. The process is applied to non-metal materials.
The process is called sublimation, as the laser beam focuses on a specific place until the material reaches its vaporizing point.
While dealing with the laser cutting process directly, some safety precautions should be practiced to avoid accidents.
Let&#;s talk about the precautions and safety rules that we need to follow according to the category of lasers.
To ensure the safety of people, including the environment, it&#;s essential to understand what Class 3 and Class 4 lasers are and their code of conduct. Without following these measures, you may expose your eyes and skin to potential harm. So, laser safety procedures are highly encouraged and, in many cases, are obligatory.
Based on their power output, All the lasers are classified into two classes- class 3 and class 4. Again, class 3 lasers are divided into classes- Class 3A and Class 3B.
The lower power output generator lasers are comprised under Class 3A. This laser power output can cause eye injury through direct viewing for a long time. Under normal circumstances, they are considered safe.
On the other hand, class 3B lasers are considerably more powerful. These lasers can cause forthright eye damage upon direct exposure. So, strict safety precautions are a must when dealing with those lasers.
The highest power categorized lasers are considered the most hazardous. These types of lasers are comprised of Class 4 lasers. The eyes and skin can be seriously injured due to the intense energy. Also, fire hazards may be caused in this situation.
Understanding the classification can help one to establish safety protocols. Proper safety, compatible training, and protective measures are indispensable when dealing with laser machines. By doing so, you can appease the ultimate risk and ensure safety.
Choosing the right one for your industry is not very difficult now that you know the different types of laser cutters. Simply focus on your priorities, budgets, the type of product you&#;re purchasing, and the cut quality you want.
Or, compare laser cutters with CNC machining to better asses your industry&#;s needs!
