Introduksjon
Laser Engraving is gaining immense popularity in the artistic and product market. Because of its faster customization ability, the demand for lasergraver has increased over the years.
Various lasergraveringsmaskiner help in carving a precise, delicate, custom pattern into a range of materials such as metal, glass, stoff, tre, and plastic.
derimot, laser marking machines, like any other machine, come with their advantages and disadvantages. This article by ComMarker gives you a detailed insight into the working principle, its benefits, and its disadvantages, and it helps you understand better.
Hva er lasergravering?
Laser engraving technology uses a strong, focused laser beam to precisely engrave designs and patterns into various materials. derimot, this process engraves really complex types of designs, mønstre, Bilder, and text into the surface of the material. This ability makes it quite popular among retailers and sellers.
Best laser engraver for small business not only benefits retailers in making products, but it also has become one of the most crucial parts of the manufacturing industry to carve details in electronic products.
Brief History Of Laser Engraving
Every new story’s beginning comes from the ending of something. Same as before laser engraving, people used manual engraving techniques. In manual engraving, people use a sharp tool to carve markings and details in the material.
For eksempel, in the beginning, years of life, cavemen used stones as an engraving tool. According to statistics, the most ancient manually engraved stones were almost 500 centuries ago.
derimot, the process of manual engraving started evolving with the rise of technology. Albert Einstein was the first person who gave the idea of inventing LASER in 1916. This idea got optimized in the year of the 1950s.
Theodore Maiman became the first person to invent the very first optical laser in the world. Golden Gould was then known to be the first person who successfully invented the laser light.
Etter det, i 1965, Western Electrics invented the first laser drilling machine. Until 1967, the laser machine was, in real terms, used for engraving purposes after the invention of the CO₂ laser.
The ultimate revolution in technology advanced the laser machines and invented specific machines for engraving, which included MOPA and UV laser markers.
Working Principle Of Laser Engraving
Laser engraving works with a highly focused laser light precisely pointed on the surface of the material and removes the part of the material, and leaves deep marks. derimot, the process does involve quite a few steps. Some of them include:
●Laser Source
The laser engraving machine has a laser source that acts as a heart for it. This source emits a constant light beam. Laser engravers use the two most common kinds of laser, which include fiber lasers，UV lasers and CO₂ lasers.
Fiberlasergravere are considered best for engraving on materials like plastics and metals (metal laser engraver), while CO₂ lasers work best for acrylics, lær, and wood.
●Focusing Optics
It contains a highly focused optic that focuses and directs the beam of light set on the surface. This optic ensures a strong and precise energy emission.
●Materialinteraksjon
The highly focused beam falls on the material. On its interaction, it heats the surface to such a point that it starts melting or vaporizing depending on the material’s nature. The material is removed in a controlled way which creates a design or pattern.
●Computer Control(lightburn software)
Best fiber laser engraver has a computer-controlled system. The system requires a digital design file as input. The software then translates the digital design and sends instructions to the laser. derimot, this controlled laser system gives a highly complex and precise design.

- Focused Energy Concentration: The basic phenomenon of laser engraving is focused energy concentration. The laser beam focuses on a certain area of the material.
When this happens, we can remove this certain part and engrave it as we want. Therefore energy concentration is important, and we need to regulate it at the same time to prevent any kind of damage.
- Wavelength Selection for Material Interaction: It will be better to study the workpiece material before starting the laser engraving process. This is because it is important to understand that different laser sources produce different wavelengths of lasers. Problems can occur when we are not using the accurate wavelength for the materials.
- Pulse Modulation and Power Control: Pulse modulation and control are important when it comes to laser engraving. The reason is that both these factors are important to bring out precision in the final product.
The intensity and concentration of the laser beam are also regulated by these factors. Due to this reason, we are able to produce quality and industrial-grade engraved products for different domains.
- Computer Numerical Control (CNC) Presisjon: The combination of laser engraving and CNC machining is crucial for guaranteeing a hundred percent precision in the products. Both these methods prove to be highly effective for the seamless cloning of the products without even damaging their structure and quality at all.
- Material Interaction Expertise: To perform laser engraving, the selection of material matters a lot. We need to understand that every material responds differently to the laser beam. Due to this reason, it is beneficial to understand the nature of the material before introducing a laser beam to it.
- Air Assist and Exhaust Systems: Engraving produces fumes that are toxic in nature. Due to this reason, it is important to set up a proper ventilation system to vent these fumes out successfully. Også, the exhaust system will be beneficial to remove the dirt and debris during this process at the same time.
- Preventive Maintenance and Calibration: It will be better to maintain the laser engraving tools in the long run to reduce the chances of failure and damage on all counts. These measures will also reduce the chances of replacements during important order production as well.
- Effective Cooling Mechanisms: It is essential to rely on suitable cooling systems when we are aiming for laser engraving. The reason is that extremely hot temperatures due to laser engraving can melt down surrounding sensitive parts and can also damage the workpiece itself.
Advantages Of A Laser Engraving Machine
●Presisjon
There is no doubt in saying that precision is considered one of the most beneficial qualities of laser engraving devices. They have the ability to engrave or etch highly complex and delicate patterns on a vast range of materials like glass, tre, metaller, etc.
