You’d want to use a laser beam, appropriate for the size you want the slice or the cut to be.
How Does Laser Cutting Work?
Laser cutting can directly be weighed or compared to the idea of melting, but at a high speed.
Source: Geum Tech
The laser beam is what you’ll use to melt the workpiece you’re working on. When it’s melted, nitrogen of high pressure is released and it blows the molten material out of the way.
Laser cutters are machines or equipment you use to cut metal, concrete, wood, etc.
It’s the machine that helps you in “cutting” or “slicing” your workpiece precisely and accurately.
Parts of a Laser Cutter Machine
In this part, your manufacturer might add something that’s not part of the norm.
However, the usual parts and components of laser cutters include:
This is the part of the machine that produces the light source.
You can think of it as the “engine” in the car because it’s what provides the laser in a laser cutting machine.
Laser Cutter (Head)
From the generator, the light beam is manifested through the laser cutting head.
It’s comprised of the focusing lens, the nozzle, and a tracking system.
You can consider the motor as the primary component of the movement or the motion system. Your laser cutter’s movement is based off of the efficiency of the motor.
Laser Cutter (Frame)
The frame of your laser cutters is like the case or the body of your device.
A carefully engineered frame is like the foundation of your machine’s durability.
This is the bridge between your laser cutter and generator, as well as the motor.
It’s the part that regulates everything so that they function as they are.
The CPU or the processing unit of your machine; it’s where you can control the actions of your laser cutters.
Laser means heat, so you’d need something that can cool it off – that’s what water chillers are for.
It’s a device that helps in converting electrical energy into light energy.
Your lasers wouldn’t run without something that can kickstart it – that’s what gas is for.
Gas cylinders are used to supply gases to laser oscillations, creating the light source.
These are the main components of a laser cutting machine. Take one out and you wouldn’t be able to use it properly.
How Much Does a Laser Cutting Machine Cost?
If you look online, you’ll find that there are a lot of options for laser cutters.
You’ll see claims that there are machines that cost under $200, but those aren’t true. Typically, you can expect to pay upwards of $4,000 for it.
In fact, it can even go as high as $20,000 for a laser cutter that’s complete with functions and features you can’t find with other equipment.
Basically, laser cutting machines and laser engraving machines are the same. What’s different is the process of each of them, how they’re used and done.

There are laser cutters you can use to engrave or mark, that’ll just depend on the power and speed.
However, it’s worth noting that laser cutting and laser engraving are different processes.
Laser cutting is the process of slicing or sectioning a workpiece, all the way through.
Laser engraving, on the other hand, means marking a workpiece by removing a part of it.
What Can Laser Cutters Cut?
Laser cutting equipment are powerful machines you can use for the benefit of your operations.

You can use it to cut almost anything, some of the most common include:
Steel and Metal
The Best Laser Cutter for Small Businesses
If you have a small business, what would be the best laser cutters for you?
There are a lot of machines you can choose from in the market. But, among the best ones (as well as the most expensive ones), are:
Orion Motor Tech 60W Laser Engraving Machine
Vevor Laser Engraver 50W CO2 Laser Cutter
Ten-High CO2 Engrave Machine
Mophorn Laser Engraving Machine 130W
Glowforge Plus 3D Laser Engraver
Apart from these, there are other machines you can choose to use for your business that are cheaper and more affordable.
How Can Laser Cutting Equipment Cut Metals?
With their power and their composition, they’re able to cut through the strongest of steel plates.
Source: Craft Cut Guide
More often than not, laser cutters that have high CO2 power and capacity can cut through many materials and objects, including aluminum and stainless steel.
Can Lasers Cutters Cut Ceramic Too?
If lasers can cut through steel and metal, it’s not a question of whether they can cut ceramic.
The usual procedure specifications of cutting through ceramic is done either through a 9.3 micron CO2 laser, or a 10.6 micron CO2 laser.
Laser Cutting Equipment For Wood
You can use laser cutters if you’re looking to cut, etch, or engrave wood.
The power of these lasers wouldn’t just help you in marking wood; you can also use it to cut or slice through it.
Of course, you have to use the appropriate laser cutter for this procedure.
Choosing or selecting an incorrect machine can lead to low quality output – or worse – the destruction of your workpiece.
Different Types of Laser Cutting
Laser cutting is actually identified and classified in various ways and types.
The fiber laser type of cutting does not fall far from how crystal lasers function.
Fiber lasers are the most sought after type of laser cutter today. One main benefit it has over other types is that it has the longest service life.
Gas lasers utilize nitrogen (compressed gas) to do the engraving, etching, or the cutting. Through electrically stimulating compressed CO2, it can release a powerful source.
Crystals are powerful materials that you can use for laser cutter.
The medicine and the pharmaceutical fields found crystal lasers their best bet in cutting various objects back in the day.
These three (3) are the different types and kinds of laser cutting techniques.
Pros and Cons of Laser Cutting
Before you decide on which laser cutting machine you want, do you know its pros and cons?
Source: Scholarly OA
It is imperative for you to know the advantages and disadvantages of laser cutting.
Some of the main advantages of laser cutting include:
Precision and Accuracy
The number one advantage you can get would be the accuracy and precision of work.
Since the lasers are thin and they’re not something solid, you wouldn’t have to worry about measurements.
More often than not, you don’t need post-treatment after you finish your projects with laser.
Lasers wouldn’t need the action of manpower; although it requires control, that would be it!
You don’t need a worker to hold the weld head, so you can designate workers to other processes and procedures that are far more important.
If you’re looking to create workpieces that are identical, laser cutters will never fail you.
You can use laser cutting equipment to create identical workpieces with maximum accuracy!
Flexibility and Versatility
With lasers, you don’t need to think about which one to use (like saw blades and drill bits).
This is because you can set the power, speed, as well as the movement of the lasers depending on how you need it to be.
The major drawbacks you can experience with laser cutting are:
Prices and Rates
Probably the most hated con would be the rate. There aren’t any cheap laser cutters if you want 101% quality to be met.
This is the investment that you need to accept if you’re looking at using laser cutting machines.
Limitations on Workpieces
Thermal cutting is known to be a procedure that can help you work on a wide range of workpieces, regardless of the size, thickness, or the diameter.
With lasers, though, going too thick can disappoint you. While there are lasers that can accommodate inches-thick of metal or steel plates, it’s going to be expensive and hard-to-find.
Expertise and Skill
Unlike other cutting types, laser cutting would be the most efficient if you are skilled.
You need to be knowledgeable about the capabilities of lasers on certain materials. Disregarding this can lead to inefficiency and negative productivity.
Mechanical cutting is the traditional way of cutting workpieces. It can include machining, tooling, or water jetting, milling, and so on.
Source: Research Gate
If you want a traditional approach to cutting, you should go for mechanical cutters. However, you’d have to treat and polish it.
Laser cutting, though, can apply finishing to a product right after the cutting is finished.
Whether you use gas (CO2), crystals, or fibers, you can get the finished product in a fashion where you don’t have to worry about post-processes.
But, you might not find it good if you’re not into the complexity of laser cutting.
DIY Laser Cutters
If you think buying laser cutting equipment is too much money, you can go to the DIY laser cutter path.
With this, you need to secure yourself a frame, a laser head (tube of 40, 50, or 60W), and a motor.
Also, you need to make sure that you’re knowledgeable in programming it so you don’t have to hire someone to do it for you.
Where Can I Find Cheap Laser Engravers?
You can search for “cheap laser cutters” or “cheap laser cutting machines” and you’ll see a lot that are under $300.
There are a ton of brands to choose from, there’s Bachin, NEJE Master, Suncoo, and so on. But, you should expect that cutters under $300 can’t do much for you if you aim for quality.
It’s still best to invest on real and high quality laser cutters to guarantee excellent and high quality results!
