Do you know “laser engraver”? It is a machine that can engrave letters and pictures on wooden, leather, acrylic boards and glass with the power of laser. It used to be a very expensive machine used by metalworkers and plastic sawmills to cut out materials. However, laser engraving machines with specifications that can do small engraving on small materials are relatively inexpensive. Depending on how you use it, you can engrave logos on ready-made products, or engrave one-point marks on small accessories, expanding the expressive power of DIY.

Laser Engraving Machine Guide For Beginner
How does laser engraving work?
As the name implies, a laser engraving machine is a machine that engraves the irradiated part with heat. Materials such as wood and cloth are sculpted by irradiating a laser and scraping off the material little by little. If you have an inkjet printer in your home, it is easy to get an image, but the inkjet printer applies ink one line at a time while the head moves left and right. The laser engraving machine also engraves characters and pictures by moving the laser head while shaving the part to be engraved at a time.
The type of laser
There are three types of lasers emitted by laser engraving machines.
Widely used in general laser engraving machines currently released. The CO2 laser uses carbon dioxide as a laser catalyst. By mixing multiple gases with the carbon dioxide in the laser transmission tube, energy is generated and the laser is emitted. Because of its good energy efficiency (fuel efficiency), it is used in desktop laser engraving machines and medium-sized laser engraving machines.
Since engraving is performed with thermal energy, materials other than metal can be engraved constantly.
2. Fiber laser
This is a method that uses solids (such as artificial crystals such as ruby and glass) for the laser catalyst, and boasts about 100 times the output of a CO2 laser. Because of the high accuracy of the laser, it can be engraved on metal, and engraving with higher definition than CO2 laser can be done.
3.YAG laser / YVO laser
This is almost the same output as a fiber laser, but can emit a laser with higher accuracy than a fiber laser. However, the parts are expensive and are often found in commercial laser engraving machines.
Because it can be micro-processed, it is often used for processing industrial products such as automotive parts and medical equipment.
Laser irradiation method
There are currently two types of laser irradiation methods for laser engraving machines.
1. Flat head type
The engraving is performed by moving the laser irradiation head on the plate-shaped processing surface. As mentioned earlier, the material is irradiated with a laser in a manner similar to a home inkjet printer. If you know the inkjet printer, please imagine it. The movement is almost the same.
2. Galvano type
The flat head type irradiates the laser by moving the head, while the galvano type changes the laser irradiation position and engraves by changing the angle of the mirror. For example, As a child, you may have played with the mirror in your hand reflecting the sun’s light and shining light on the walls of your house. Unlike the flat head type, there is no need to move the head, so engraving can be performed at high speed.
How to choose the best laser engraver?
Laser engraving machine have different wattages. The higher the wattage, the deeper you can carve. Even with low power, you can cut paper, carve plastic surfaces slightly, or burn wood to engrave. If you want to carve deeper, it is better to select one with high output, but even with low output, you can get the depth by carving the same pattern many times. However, because of the heat, the material may be distorted due to burning or heat.
With an output of 1000w, wood, bamboo, plastic, leather, rubber, cork, etc. can be engraved. At 1500w, you can engrave even deeper, and thin materials can be cut.
Carefully consider what to process and whether it is necessary to cut with a laser engraving machine and select the engraving machine with the optimal specifications.
About the depth of engraving
In general, laser engraving machines do not have a clear standard of “engraving how many mm ”. Setting the laser output and the head moving speed will change the depth .
The longer the irradiation time, the deeper the engraving can be done, and the slower the head moves. Therefore, the balance between the laser output and the moving speed of the head becomes important. For example, if you set a high output and a low moving speed, you can dig deeper, but the heat may cause the cut surface to be distorted. If you set a low output and a high moving speed, you can engrave at a high speed, but you will not get much depth.
Note that this varies depending on the performance of the laser engraving machine, temperature and humidity, and the material to be engraved.
Safety Guidelines when using a laser engraving machine
1. Get good ventilation
Since the laser engraving machine performs engraving with heat, the engraved surface is scorched or melted. Naturally, smoke, gas and smell are generated. When processing paper, the smell of baked sweet potatoes can make you appetite, but wood smells quite strong. When processing acrylics, in addition to the smell, there is also the emission of gas from the burning of plastic products, which can be harmful to the body. Work in a well-ventilated area, such as near a ventilation fan.
2. Prepare fire extinguisher
During engraving, smoke (flammable gas) is generated depending on the material. The higher the power, the more the laser ignites the gas and a small flame may be emitted. Most of them disappear instantaneously, but they can cause a fire, so prepare a fire extinguisher.
3. Do not look directly at the laser beam
Laser engraving machines may generate intense light during processing. This can cause eye damage. It is fun to watch the material being carved, but it is dangerous, so wear laser protection goggles or do not look at the light generated during processing.
4. Absolutely no PVC resin material!
When heat is applied to PVC-based materials, toxic gases are generated, which is extremely harmful. In addition, gas attacks machine parts and shortens machine life. Never process PVC-based materials.
5. Do not engrave the mirror surface material!
Mirrors reflect the irradiated laser and damage the laser tube. Do not process mirror-finished materials or materials that are likely to reflect laser, as it may cause damage to the machine.
6. After a break in continuous processing
When laser engraving is performed for a long time, the laser transmitter becomes hot and the laser output drops extremely. If engraving machines are equipped with a water-cooled unit or other cooling, so you dont worry. The continuous processing time varies depending on the machine, but read the manual carefully, grasp the continuous engraving time, and do not process for a long time.
With a laser engraving machine, your idea becomes a shape, it is very interesting, and if you master it, the range of expression can be expanded at a stretch with DIY. Why do not you buy a laser engraving machine at this opportunity? You will enjoy it!
