What is Laser Engraving?
A laser (light energy converted into heat energy) is a type of energy used for the fabrication of metals and non-metals materials. Except for fabrication, laser technology is also highly used in print & advertising media for brand marking, energy, and etching on metal & non-metal material stuff.
Laser application is a very fast, cost-effective & precise process, compared to the traditional fabrication, and carving tools that produce a rough finish, a more time-consuming & pricy process.
As LASER’s name denotes “Light Amplification of Emission by Radiation” is a technology based on light energy.
3D Printing and Laser Technology are both industry future is bright coming years.
Co2 Laser Technology Invention
Co2 laser technology was invented in America in 1963, by an Indian-born scientist named Kumar Patel. Still then being used in the professional, architectural, and industrial sectors. Find the ultimate guide on how laser technologies & machine works.
What is laser engraving? we have to understand the first laser engraving principle before making a buying decision for a laser engraving machine. Now a day branding through laser technology is trending in the brand-making space.
Even if it is marking a company logo on a metal plate, metal tag, fancy metal cards, barcode on metal products, or personalization of gift items. Laser engraving technology is a digital application feasible on metal, plastic, glass, fabric, wooden-made promotional items, and many more.
Laser Marking, Laser Engraving, Laser Etching, Laser Cutting, etc. All these words are very familiar to each other & but the difference is using of laser beam power, type of stuff, type of application & stuff thickness.
A laser can be applied to a flat, cylindric, and 3D shape object, even and uneven surfaces. Different types of shape products required a specific model laser machine that fits bulk laser services products.
There are 4 main key points 1. OXIDATION, 2. VAPORISE, 3. MELTING & CUTTING ACROSS, on behalf of laser machines works. Each type of application and material requires a different power supply laser beam to produce a better result. So let us understand laser technology in detail.
There are two types of laser processes 1. Fiber Laser and Co2 Laser.
- Fiber laser is ideal for metal (brass, stainless steel, aluminum cooper, and its alloy for marking, engraving, & cutting applications.
- Co2 laser is better for non-metal materials like wood, plastic, fabric, paper board, etc.
The Laser Nozzle, Focal Lens, Mirror, Laser Software, Laser Reasonator, and X & Y axis are the basic components where laser quality is controlled.
Relation Between Laser Power, Cutting Material Thickness & Time Consumption
Soft materials like paper, wood, and plastic required a lower power supply to cut the stuff. Electric power supply 10 watts to the 80-watt power supply is sufficient for up to 0.5-inch thickness for all non-metal stuff for marking, engraving & cutting applications.
Laser work on metals required a high power supply above 50 watts and more for professional works and industrial uses and construction required a more than 400-watt power supply.
A high-power laser beam required a shorter time on the same thickness stuff rather than a low-power beam even if it is metal or non-metal stuff.
Laser Beam
A laser is a type of process of using a lot of energy focusing to the tiny point that produces high-intensity energy to the intended object that makes it able to burn/vaporize/melt/cut even noticeable impact without hurting the rest area.
Laser Marking:
The laser marking machine principle is based on a low-energy power supply used for marking on the plastic substrate surface, wood, cardboard, metals, etc. This application is based on the OXIDATION principle. The simple & fast process does not require laser marking tools you need a laser marking tape to keep the product neat & clean. Laser marking power varies from substrate to substrate according to material density. Laser marking on brass or any metal required a high power supply compared to the non-metal stuff.
In this application, the Laser Burn Out Only the Upper Layer of the Substrate.
Due to the oxidation on the surface level, color is converted into black and became more visible. This process is also known as the discoloring process.
Only coated or upper layer is decolored.
Required a 2D design file format.

Laser Engraving
In laser engraving works, a laser beam act deep distance, even you can feel depth & see. The laser engraving process is multi-time faster than hand engraving. Engraving on metals required high power rather than non-metal materials.
- A laser engraving machine supplies a high-energy laser power beam that VAPORATE THE INTENDED area from the object in the required shape & design that makes it more visible than the laser marking. Even you can see in your naked eye & you fill color also.
- Laser engraving work is more technical as well as how deep design you want to engrave on the materials.
- The melted material is vapourised at the same time when the laser is applied.
- Laser engraving depth can be done from 0.02 inches – 0.125 inches.
- To increase engrave depth needed to apply laser more passes.
- It required a highly ventilated area to keep the atmosphere working area friendly.

Laser Etching
Laser etching is a process when the laser is applied to the substrate to keep in mind laser power that can melt the substrate, whether it is heavy metal or light metal each metal has a different melting point. Due to high heat, the surface of the substrate is melted and makes a contrast between the melted and rest area became more visible. It also required a high air pressure that help to
- The maximum melted area could be 1 mm.
- Need to be the constant power supply
- Can be applied to metal and glass stuff to create an amazing design.

Earlier, this method was used to done by handcraft men (skill person) with various digging tools and dye casting processes. Branding was produced through dye casting a low-quality product in terms of equal depth and content sharpness.
But now engraving & carving works are done digitally in 2D and 3D product shapes with an accuracy of 99.9% with CNC machines.
“Laser engraving technology is based on supplying laser beams to the intended object digitally. These laser beams burn the upper layer of the product (coating) and created the intended design we had to send from the computer device. Produced marks are permanent.”
Usually, making a mark on the substrate is based on the laser power. Low-density made materials require a lower power supply whilst high-density products consume high power laser that vaporizes only the upper layer.
When a higher density of laser beam is applied to the stuff, it burns a layer deeper known as Laser Engrave. Deep engraved material makes it easy to fill manual colors well as registered logo or brand name
The high power of a laser beam that crosses through the material and sets apart material from the whole is known as Laser Cutting.
All the above terms are totally based on the amount of supplying power of beam onto the materials. During marking, engraving, and laser cutting create waste burns, melt or vaporize it depending on the materials used.
Laser printing technology was invented in the year the 1960s. The demand is increasing day by day. Highly used in the commercial and promotional manufacturing unit for branding purposes.
