What is Laser Engraving?

Laser engraving is a sophisticated process where a focused beam of light - monochromatic, coherent, and directional - interacts with a material’s surface. This interaction causes the material to evaporate or erode, creating a permanent mark or design. The precision of this beam is remarkable. With a spot size measured in micrometers, you achieve extremely accurate and detailed engravings.

How Does a Laser Engraver Work?

A laser module is the heart of a laser machine. Inside that small enclosed box, resides a complex laser generation setup. This setup primarily has three things: gain medium, energy source, and mirrors.

The gain medium, which can be a gas, a crystal, or a liquid, plays a vital role. When exposed to light, the electrons in the gain medium become excited, leading to the release of photons. This light energy is supplied by an energy source, typically connected to a battery or an electric power source.

Surrounding the gain medium is the resonator, a configuration of mirrors designed to amplify the optical gain. These mirrors, along with various lenses, are tasked with directing and fine-tuning the laser beam, ensuring its precision and consistency. This setup creates a controlled, focused laser beam, essential for the detailed work.

The laser module of an engraver operates under the guidance of a computerized controller, essentially the machine's brain. The movement of the laser module over the material, its power, and speed, everything is managed by the controller.

The material placed to be engraved is on the work table i.e. base of the laser engraving machine. It is flat and non-reflective, designed such that the material on it stays firm on it during the engraving. Honeycomb panels can also be placed particularly for laser cutting to protect the table and improve heat dissipation.

Process of Laser Engraving: From Digital Design to Physical Engraved Pattern

The laser engraving process starts with designing in graphic software. You create a pattern or drawing that you want to etch. This design is then exported to laser engraver software. Here, you adjust the settings for the material and finalize the design. The machine connects to your PC or mobile device, with the engraver software controlling it.

Once you start the process, the engraving begins. The laser beam, upon hitting the material, vaporizes a layer, leaving a mark. In some materials like metal alloys, this results in a colored pattern. This color change is due to a chemical reaction, often oxidation when the laser interacts with the metal's surface.

Types of Laser Engraving Machines

As mentioned earlier, lasers can have different types based on the gain medium they use. This gain medium also dictates the optical power of the laser. Commercially, these three types of laser engravers are common:

Fiber Lasers

Fiber lasers are the type of solid-state laser with fiber optic as the gain medium. They have a wavelength between 780 nm to 2200 nm; it’s readily absorbed by most materials even metals. They are the most powerful laser engravers on the market. And are commercially used in industries and commercial metal engraving needs.

CO2 Lasers 

CO2 lasers are slightly less powerful than fiber lasers; their optical power can be as low as 40W and go up to hundreds of watts. Their wavelength is close to 10,600 nm. It is absorbed by most materials but reflected by metals. They are not the preferred choice for metals but we see them as industrial and hobby laser engravers.

Diode Laser

One of the lasers that is commonly used in desktop and hobby laser engravers. They may not be as powerful as CO2 or fiber lasers, yet they are compatible with a wide range of materials for engraving. Whether it’s wood or metals, they are equally good on both surfaces. Another benefit, they are largely less priced compared to the other two lasers.

How to Use a Laser Engraver?

If you have recently bought a desktop laser engraver, here’s a generic process to use it for engraving:

1. Design Preparation

laser engraving design preparation

First, you need a digital design you want to engrave on the material. You can create this in laser design software such as Adobe Illustrator or CorelDRAW. Alternatively, you can also download the free laser engraving files from the Internet.

2. Laser Engraving Software Setup

Next, install a laser engraving software. This software not only controls the engraver but also optimizes your design for the engraving process.

For engraving, grayscale images are often essential. Your software should allow you to import and convert images into this format to facilitate depth and shading in engravings.

Lightburn is a popular choice for laser engraving software. However, many manufacturers offer their proprietary software. For example, xTool machines are compatible with their custom-built xTool Creative Space (XCS), though they can also use Lightburn.

3. Choosing the Material and Optimizing

The laser control software also has a setting for materials. You can optimize the machine's power and speed based on the materials. We recommend using the manufacturer-recommended setting. If you’re using any of the xTool machines, use these materials settings for successful laser engraving operation.

4. Adjusting the Laser Module

The last step is the correct material positioning and adjusting the laser head. Most machines have an adjustable laser head that can be adjusted manually. Some do have auto-focus technology. To be sure, refer to the user manual and machine specifications.

Safety Precautions for Use

Although laser machines come in enclosures, where there’s minimal chance of laser exposure. Still, to avoid any mishap during the operation process, follow these precautions:

  • Ensure Adequate Ventilation: Laser engraving can produce harmful fumes, especially when working with plastics or coated materials. Use a fume extractor or smoke purifier to make sure the workspace is well-ventilated.
  • Fire Safety: Never leave the laser engraver unattended while it’s operating, as there is always a risk of fire. Keep a fire extinguisher nearby, especially one suitable for electrical fires. 
  • Operate in a Safe Environment: Keep the area around the laser engraver clear of flammable materials and clutter. Also, ensure the engraver is placed on a stable, flat surface to avoid any accidental movements or tipping.
  • Read the Manual: Familiarize yourself with the specific safety features. Learn what modules it has for emergency shutdown and in case fire erupts. Follow the recommendations of the manufacturer.

Tips for Successful Laser Engraving

To get the best results, here are a few additional tips to follow:

  • Use the Correct File Format: Understand the difference between raster and vector engraving. Raster images are best for detailed designs with gradients, while vector files are ideal for crisp lines and text. For 3D engraving, utilize grayscale in raster images to represent different engraving depths. Darker areas will be engraved deeper than lighter areas.
  • Use Manufacturer-Defined Settings: Start with the manufacturer's recommended settings for your material, which are often well-tested. Plus, you may test-run the engraving on a sample material workpiece.
  • Use an Air Assist: An air assist is worth it for laser engraving. It directs a stream of air at the engraving point, helping to reduce flare-ups and heat marks on the material. Especially, recommended for wood engraving where burnt marks are a common sight.
  • Maintenance and Checks: Keep the machine clean, as built-up debris can be a fire hazard and can also affect the quality of your engravings. Also, inspect the laser module for any signs of wear. If anything is compromised, immediately replace it.

How Much is a Laser Engraver?

The price of a laser engraver can vary widely, ranging from $500 to $500,000. This reflects the diversity of laser engraving machines, from desktop models to commercial-grade machines.

  • Desktop Engravers: These are more affordable, starting around $500, and can go up to $5,000. They are suitable for small businesses or personal use.
  • Industrial Engravers: Prices for these start from $5,000 to $10,000 and can soar to several hundred thousand dollars. They are designed for heavy, continuous use and offer advanced features and larger working areas.

However, the exact cost of these machines is dependent on a range of factors. We discussed that in a separate post on the cost of laser cutting machines. Here’s just a review of the factors:

Type of Laser

Fiber laser engravers are the most premium machines, designed for industrial use. Then, slightly less-priced are CO2 lasers. They too are used in industries, however, compact variants for small businesses and home usage are available. Diode lasers are the most cost-effective lasers in the market.

Optical Power

Optical power also dictates the price. More powerful lasers require advanced internal components, which adds more cost to the machine.

Working Area 

The size of the laser engraver’s working area is directly proportional to its cost. Industrial machines with larger beds and robust moving parts are more expensive than smaller, desktop versions.


Special features like interchangeable laser modules, built-in air assists, auto-focus capabilities, and enhanced safety measures add to the engraver’s functionality and safety but also increase its price.

How to Choose a Laser Engraving Machine?

If you’re looking to buy a new laser engraving machine. But are confused about where to start, here’s a list of technical aspects you need to look into before buying:

Optical Power

Determine the depth of engraving and cutting you need. More optical power is required for deeper engravings or cuts. However, optical power should not be confused with electrical power/machine-rated power. 

Optical power is the energy you’re receiving at the end of the laser module, it’s mostly advertised in laser names. Let’s take the example xTool P2, it’s a 55W laser engraver i.e. its optical power is 55 watts.

Whereas, rated power is the electrical energy it consumes when the laser operation begins. It is always greater than the optical one as most of it dissipated during the laser gain and amplification. The engraving machine with less rated power and more optical power is an efficient one.

Material Compatibility

Generally, all laser engravers are compatible with most of the materials (wood, leather, fabric, acrylic, cardboard). However, metals are an exception. For metals, fiber engravers are the best. Whereas, for coated metals, you can use CO2 or diode lasers.

Working Area 

Do consider the size of the items you plan to work on. Will they be small, intricate pieces like jewelry or decor crafts or larger items like signs?

Make sure that the machine's bed size aligns with the types of projects you intend to undertake. The working area should accommodate your largest planned project to avoid limitations in your work scope.

Engraving Modes

Look for a machine that offers multiple engraving modes. Besides standard flat surface engraving, check if the machine supports rotary engraving (for engraving cylindrical objects) and can handle curved or uneven surfaces.

Laser Engraving FAQs

Is Laser Engraving Hard to Learn?

Laser engraving is relatively easy compared to traditional engraving methods. It is simple enough that beginners can start their engraving projects with just a few tutorials and a user guide.

Is Laser Engraving the same as Laser Cutting?

Laser cutting and engraving are different operations. In cutting, the laser vaporizes the material from the surface to the bottom end, making a clean cut. Whereas, in engraving the material is precisely removed from the surface layers.

Does Laser Engraving Use the Same Machine as Laser Cutting?

Yes, most laser machines are capable of both engraving and cutting. A typical laser cutter can also perform engraving tasks. However, machines designed specifically for low-power engraving may only cut a few millimeters of thick materials. 

How to Add Color to Laser Engraving?

In metals like stainless steel, color laser engraving results from a chemical reaction between the laser and the material. An oxidation reaction creates various colors. In other metals, you can replicate the process by applying a colored oxide layer before engraving.

How Deep Does Laser Engraving Go?

Typically, laser engraving is a surface technique, with standard depths around 0.02 mm. However, by adjusting the settings, you can engrave deep to a few millimeters (up to 3mm) inside the material.

How to 3d Laser Engrave?

3D laser engraving involves varying the intensity of the laser beam to remove material at different depths. This creates 3-dimensional patterns on the material. To 3D engrave, you need a laser engraver that is compatible with grayscale images. 

What’s the Difference Between Laser Engraving and CNC Engraving?

CNC and laser engraving both use distinct tools. In laser engraving, an intense laser beam vaporizes and removes the surface material. Whereas, in CNC engraving, a rotary router contacts the surface and mechanically removes material by carving or milling the surface.

What are the Differences between Laser Engravers and 3d Printers?

Laser engravers and 3D printers work on two different principles. 3D printing is an additive process. A material (plastic filament) is built up layer by layer to form an object. In contrast, engraving is a subtractive process. It starts with a larger piece of material and uses a laser to cut away layers, forming the final design.

How to Maintain a Laser Engraver?

Inspect and clean the lenses, check the tension in the belts, and lubricate the pulleys. In winter, use the laser engraver in a place where the temperature is close to standard room temperature.

What’s the Difference between Laser Engraving and Laser Marking?

In laser engraving, a high-power laser removes material from the surface to create deep, tangible cuts. The depth can range from 0.001 to 0.125 inches. Whereas, in laser marking, little or no removal material takes place. Instead, a low-powered laser chemically reacts with the surface, leaving a permanent, decolorized mark.

What’s the Difference between Laser Engraving and Laser Etching?

Laser engraving removes material to a significant depth, leading to a 3D appearance and noticeable texture. Laser etching is a subset of engraving, where the material is melted but only at a micro-surface level.
