Throughout time, laser engraving has been used by large companies, but due to the technological progress of this type of device, the prices for laser engraving have started to decrease.
How deep can a laser engrave a material?
One of the most common questions about laser engraving is how deep it can be. There are three types of laser engraving, with different marking depths. These are:
- Laser marking;
- Laser engraving;
- Embossed laser engraving.
Laser marking
Laser marking is a process by which a laser beam imprints symbols and signs on the surface of a material. This process is often used by companies to engrave various branding marks on their products such as: company name, QR codes, company logo and so on.
This method is differentiated from laser engraving by several aspects:
- It is not as widespread a method as engraving;
- One of its names is laser coloring, carbonization for plastics inscription and annealing for metals;
- Compared to laser engraving, this method does not change the surface of the material, only changes the appearance by one of the methods listed in the previous point.
The maximum depth of the laser marking is usually between 0.001 and 0.002 mm.
Embossed laser engraving
Embossing, which is similar to laser engraving, uses a process by which, with the help of a laser beam, the surface material is melted. This technique uses a significant amount of heat to melt the metal and make a more prominent inscription.
The difference between embossing and laser engraving:
- The first of the two methods uses excessive heat to elevate the surface, thus creating a textured symbol, compared to engraving, which destroys matter, digging into the material.
- Greater depth difference between the two.
The maximum depth of laser ablation is less than 0.025 mm.
Laser engraving
This is by far the most popular method when it comes to laser engraving methods. It uses a process by which a laser light beam uses concentrated heat to vaporize the material, leaving room for a cavity, that is, the desired signs and symbols. The maximum depth of laser engraving is about 0.5 mm, but depending on the material, it can even reach 3.15 mm.
Laser engraving is a technology that can be used on a wide range of materials such as:
Wood
It is one of the most popular and common materials used, both for beginners and experienced users. The wood used can be both hardwood and softwood.
Metals
This is another popular material. Almost all types of metals can be engraved, including steel, aluminum, gold, titanium, stainless steel, and so on. Laser engraving is used to create jewelry, warning signs, but also in the automotive and aerospace industries.
Leather
This technology is also used successfully in the textile industry. With the help of this technology, you can create customized products such as wallets, book covers, belts, but also jewelry such as bracelets.
Lately, more and more small businesses and even individuals have started using this type of technology. Whether you use this machine for your business or just as a hobby, you can be sure that laser engraving is a worthwhile activity.
