Laser technology has come a long way. It started with big, industrial cutters and now, we have compact ones right on our desktops. The market is full of choices, and it’s pretty exciting.
Choosing a laser cutter isn’t easy, though. There’s a lot to know, and if you're not clued up, you will probably end up making a costly mistake. So, it’s important to get aware of what you’re getting into – that helps make an informed decision.
If you are a small business owner or a hobbyist looking to get into laser cutting, this guide is for you. We are going to break down the technical stuff you need to know to pick the perfect laser cutter.

What is A Laser Cutter Best For?
Traditionally, CNC routers were launched for cutting materials. Yes, they are better for 3D dimensional jobs, but for simple 2D intricacies and home usage, laser cutters outperform them in various aspects. Such as:
- 2D Design Accuracy: Laser cutters are great for 2D designs. They offer precision that CNC routers can’t match. Ideal for intricate patterns.
- Quick Operation: These cutters work faster than CNC routers. They are perfect for urgent projects.
- Material Flexibility: They handle a variety of delicate and common materials, including wood, paper, plastics, glass, leather, stones, and metals. This is a broader range than CNC routers offer.
- Gentle Cutting: Laser cutting is a non-contact process. It reduces machine wear and material stress. This extends the machine’s life.
- Ease of Use: Setting up and operating a laser cutter is simpler than a CNC router. The laser control software is quite user-friendly and often comes with support on various operating systems.
- Clean and Quiet: Laser cutters make less mess and noise than CNC machines. They also wear down fewer parts like cutting bits.
Factors to Consider When Choosing A Laser Cutter
A laser cutter, while compact, is complex inside. Understanding its functional and technical aspects helps you understand the differences among machines and choose the one that meets your needs.
Budget
The price of laser machines varies widely due to their differing sizes and types. There are large industrial machines, customized models, and desktop versions for hobbyists. This range means a broad spectrum in cost.
Industrial laser cutters are costly, starting at several thousand dollars. They can reach up to half a million dollars for large-scale commercial versions. On the other hand, desktop lasers are more affordable. Entry-level smart diode laser cutters can begin at around $500, while compact CO2 laser cutters are priced under $5,000.
Type of Laser
Lasers are classified into multiple types based on their optical medium, wavelength, and mode of operation. The common laser types we see in the industrial and desktop laser cutters are:
- Fiber Lasers: Industrially used for metal cutting, quite powerful but expensive. Can cut through a range of materials.
- CO2 Lasers: Used in both desktop and industrial cutters. Slightly less powerful than fiber, yet powerful enough for most cutting jobs.
- Diode Lasers: Slightly less-powered, but available in the most compact form. They are the least expensive of the three. Also, they are the most favorable technology for desktop and at-home laser cutters.
Material Compatibility
The ability of a laser cutter to handle different materials depends on both its power and the type of laser.
Optical Power
Optical power refers to the energy output at the laser’s end. A higher optical power signifies the machine’s ability to cut through tougher materials and thicker layers. For home-based crafting jobs, a power between 10W to 50W would be sufficient. While for industrial cutting, you need much higher power (hundreds or thousands of watts).
It is important not to mix this up with the machine’s rated power, which is actually its electrical consumption. The rated power is always higher than the optical power due to energy loss during conversion.
Working Area
The working area, also known as the processing area or bed size, is important. It is the space where you perform your cutting tasks. When selecting a machine, ensure it can accommodate the dimensions of your projects.
Industrial machines often feature a large bed size, sometimes with a conveyor for added functionality. Desktop models have a smaller working area but are still suitable for various small crafts. Some models come with a pass-through slot, allowing for an extended working area. This feature is beneficial for projects requiring longer lengths.
Speed and Accuracy
Laser cutting is renowned for its speed and precision compared to traditional methods. Speed is measured by the length the laser head can cut per second. It is typically listed in mm/s or inches/s. Industrial fiber lasers are usually faster, starting at a few thousand mm/s. For desktop versions, speeds range from about 300 to 600 mm/s.
The cutting time matters if you’re a small business selling crafts. So, choose a machine that is quicker and has high motion accuracy.
Conclusion
Buying a laser machine should be a well-considered decision, not an impulsive one. It should be backed by research and knowledge of the technical aspects involved. In this article, we have outlined all the basic factors you need to consider before making your purchase. We hope that helps in making an informed decision.
