Laser cutting is a subtractive manufacturing technique for cutting various materials through the use of a laser. When the machine engraves or cuts material, it uses a thermal system to remove the material. The laser power on a small area heats melts and vaporizes the material. The entire procedure is computer controlled, guiding the path the laser should follow to create the cut. The material is flat and generally thin.
Laser engraving and cutting are used for applications in engineering, education, or for decoration. Compared to other manufacturing techniques, laser cutting is economical and often preferred for the creation of small series requiring a high level of detail. The machines can be used commercially for industrial applications as well as by amateurs.
By choosing to use laser cutting, you will have the choice between different cutting techniques, and materials, but also different cutting machines. It is possible to laser cut many materials such as wood, plastics, but also metals.
What are the best laser engraver and laser cutters?
Laser engravers and laser cutters use subtractive manufacturing technology (unlike 3D printing, also called additive manufacturing). Their laser selectively burns or melts matter, following precise digital instructions.
With a laser cutter and laser engraver, you can add a personal touch to objects of your choice or create your own bespoke pieces. There are, however, a multitude of laser cutting and engraving machines on the market, and it can be quite difficult to find the best laser engraver for your needs.
Are you looking for the best laser engraver for a small business? Then this guide is just right for you as here we have considered all the points to look for.
Buying Guide: What to Look for in a Laser Cutter/Engraver for Small Business?
Before buying a laser engraver for tasks like creating personalized gifts, check out the things you need to consider before making your purchase.
Laser power:
This is probably the most important thing to consider when looking for the best laser engraver for you. If you have a high-power laser, chances are you can engrave and cut thicker materials than with a low-power laser.
Most of the time, manufacturers indicate the laser power of their products in W (watts) or mW (milliwatts). When the power is expressed in milliwatts, it is generally because the laser is not very powerful.
Budget:
The price of a cutting and engraving machine can vary between $100 and $10,000 (or more for industrial models). The general rule is that the more expensive the device, the higher its laser power and therefore the better its ability to cut materials.
However, you should always consider your needs. You might find a model that doesn't cost a fortune but is versatile enough to meet your expectations.
Software:
Whether you only need a hobby laser engraver or a professional unit, you want one that offers software support. These days, most cutting and engraving machines come with adequate software.
There is no doubt that the software makes working with a laser engraving machine easier. Software developed by manufacturers for their own machines is 100% compatible, but many devices also support third-party software. This includes CorelDraw, AutoCAD, and solutions made by Adobe or other reputable developers.
Materials:
A desktop laser engraver can process a wide variety of materials. The list includes paper, leather, metal, various fabrics, etc. Before buying a particular unit, you need to make sure that it can handle the materials you plan to engrave or cut.
Laser cutting and engraving: FAQ
What is a CO2 laser engraver?
A CO2 laser engraver is a machine that can engrave materials using a carbon dioxide laser beam. CO2 lasers are among the most efficient types of lasers available today. They can cut through a wide selection of materials like wood, metal, plastic, or acrylic.
What is a fiber optic laser engraver?
A fiber optic laser engraver uses fiber optic lasers for excellent precision and fast speed. They are renowned for their long life and low maintenance, which helps to deliver consistent results.
Where can I buy a laser engraver or laser cutter?
You can get a laser cutter from your local hardware store or specialist dealer. However, if you want to take advantage of a wide range of units and be sure to choose the one that perfectly suits your needs, you can do it online. There are many choices on Amazon.
What can a laser cutter cut?
A laser cutter can cut wood, leather, plastic, rubber, foam, glass, and more. The sturdiest machines can even handle metals, ceramics, and crystals. It depends on the device you buy, but laser cutters are known for their versatility.
What is a CNC Router?
A CNC router is similar to laser cutters/engravers, except there is a different tool head. It carves and cuts materials using a drill instead of a laser.
Should you use a laser cutting machine or a laser cutting service?
A laser cutting machine, whether industrial or desktop or a multi-function machine, will always be an expensive investment. In addition to the cost of the machine, there are also the costs of maintenance, materials, etc. You will also need to learn how to use and repair the machine. There is also the loss of materials during cutting and their cost. A simple and effective solution if you want to save time and money, use a laser cutting service. By using an online service to create your projects, you don't have to worry about these different aspects and expenses.
Laser cutting materials can be available in many thicknesses, which influences their stiffness, as well as their mechanical properties.
