Laser marking uses a low-power laser beam to leave lasting marks on materials. This is achieved by changing the appearance of the material using material oxidation. During this process, the material surface remains intact and the final mark is clean and defect-free.

Engraving, on the other hand, removes material by evaporation. Using a high-power laser beam to remove the outer surface of the material, it can be engraved to a depth of 0.020 inches in metal (but 0.125 inches in materials such as graphite).

Laser marking is commonly used for logos, barcodes, QR codes and other text markings on plastics and metals, while laser engraving is used on metal, thermoplastic, glass, leather and wood surfaces. Some machines can both mark and engrave, while others are dedicated to one or the other.

Types of laser marking and engraving machines

atomstack a5 m40 laser engraver

laser cutter machine

There are four types of laser marking and engraving machines. Some are suitable for marking and engraving, while others focus on one of the two:

UV laser
Designed as a practical solution for marking plastics and glass, UV lasers can engrave a wide range of materials, from metal to paper.

These lasers are designed for high-density and low-density polyethylene and synthetic fibers, making them suitable for laser engraving applications where product surface protection is required.

Fiber-optic laser
The most popular type of laser for marking and engraving. A fiber laser is a solid-state laser with a very small focal diameter and much greater intensity than a CO2 system.

atomstack a5 20w laser engraver

These are ideal for permanent marking, including serial numbers and barcodes. Additionally, because they can produce strong laser marks with extremely small focal lengths, they are ideal for metal engraving (including coated metals) and high-contrast plastic markings.

CO2 laser
Although one of the first gas lasers to be developed, CO2 lasers remain one of the most useful types and are the highest power continuous wave lasers currently available.

Modern CO2 lasers generate a laser beam in a sealed glass tube filled with gas (usually carbon dioxide). The high pressure then passes through the tube and reacts with the gas particles, increasing their energy and producing light.

CO2 lasers are commonly used for cutting and welding. Low power CO2 laser marking machines are more suitable for non-metallic materials and plastics.

YAG laser
YAG lasers, often referred to as flash lamps or lamp-pumped lasers, utilize a lamp (bulb) as the pumping mechanism and a crystal as the gain medium. Both are located in optical resonators that reflect light and help generate laser light.

atomstack s20

Although widely used throughout the manufacturing industry, bulbs are becoming obsolete due to their short lifespan and frequent replacement

Advantages and disadvantages

UV laser

Compared to other laser wavelengths, UV lasers require much lower power to produce clear marks and absorb better by almost all materials. Also, unlike other marking and engraving techniques, there is no long downtime, which means the process is - often - very quick and easy.

Marks produced by UV lasers are essentially tamper-proof because they sit below the surface of the material and the material does not come into direct contact with the laser marking equipment. This allows for clean operation and minimal contamination. It is because of these capabilities that UV lasers are frequently used in the medical and pharmaceutical industries.

fiber laser engraver

Fiber-optic laser

Fiber lasers are ideal for marking difficult materials such as gold and nickel plating, plastics, PCBs and other sensitive materials and layers. They can also be used for deep engraving and annealing smoothing of medical devices.

Fiber lasers are suitable for deep engraving when combined with a high power master oscillator power amplifier (MOPA). MOPA will increase the peak power output of the laser and optimize beam quality for precise marking and deep engraving.

Overall, fiber lasers are high-performance, reliable and often compact compared to other laser marking and engraving machines.

Due to its simplicity and industrial compatibility, portable laser engravers can be used in many industries to mark many materials. There are many options for portable laser engravers.

You can visit Atomstack to buy laser engravers online. Atomstack can provide you with the best laser engraver safety, laser engraver motherboard or the best CNC machine on the market.

Portable laser engravers are used in many industries to mark metals and plastics. It is easy to use and can be used for many markup projects. Some people are not sure how the machine works or how to use it.

How to choose the right portable laser engraving machine?

The key to choosing to buy a laser engraver online is understanding how it works and other prerequisites. These can be very difficult. These are a few factors that can help you choose the best portable laser engraver.

Price is an important consideration when you are looking for a portable laser engraver. Portable laser engravers are more portable than traditional laser engravers and can still be used for industrial purposes.

The features of the portable engraving machine make it easier to use. The price of one is higher than the traditional laser engraving machine.

When shopping for a portable laser engraver, it's important to make sure to check for software compatibility. There are two options.

A portable laser engraver can be purchased with the software. You need to make sure your design is compatible with the software.

It is also possible to purchase a portable laser engraver that is compatible with your software. If you create a design, it will work with your software.

Do you think a portable laser engraving machine would be easier to use in terms of power? Of course, you can use batteries! Portable laser engravers powered by wired power can work in all conditions.

When shopping for a atomstack p7 m40 laser engraver, it is important to consider the laser source. You should look for machines that use quiet laser sources to make the process more environmentally friendly.

P7 M40 laser engraver for metal cheap

This is not required, but still important. It's best to have a portable laser engraver that doesn't need to be connected to a computer. We know that many portable laser engravers use a USB stick to connect to a computer. This makes it easy to operate.

Portable laser engravers can vary in portability due to their weight. It depends on the function of the machine and the optimization of the manufacturer.

When choosing a atomstack p7 m30 laser engraver, make sure it is the right size and weight for your function. However, price is also affected by weight.

Portable laser engravers that are smaller and can be used industrially, such as portable fiber laser markers, have more features but are more expensive.

Acrylic or plexiglass is a unique material that is very fun and creative to work with, but also very temperamental.

atomstack s20 pro

Acrylic laser cutters and engravers help take a lot of the guesswork and labor that comes with working with acrylic by automating and modernizing processes, such as deburring edges and achieving clean lines.

Can you laser engrave acrylic?
Yes. Acrylic laser engraving occurs when the laser evaporates the top layer of material. Therefore, the material absorbed by the laser rapidly turns into a liquid and then a gas. Because of this vaporization, you'll need an enclosed laser engraver with a ventilation system that can direct the fumes away from the work area, such as out of a window.

In addition to enclosure, you'll need a machine with air assist to further manage steam in all aspects of your sculpting environment.

Acrylic or plexiglass are actually ideal materials for laser engraving, as the laser avoids warping the material, provides automatic deburring, and gives you precise angles and sharp edges when cutting acrylic. They are also so powerful that industrial laser cutters can process acrylic materials up to an inch thick.

How to laser engrave acrylic?
When engraving, acrylic comes in two types: cast and extruded.

Cast acrylic is made by pouring a liquid into a mold, which is then turned into a matte material that is highly sought after in custom projects such as awards.

Extruded acrylic is made by putting pellets into an extruder, which is then melted and extruded. This is an easier and cheaper option to make and keep its clear deposits during the engraving process. It is also softer than casting and is best for projects that require smooth edges.

But in general, acrylic or plexiglass will absorb certain wavelengths of light, which means you'll be able to engrave at relatively low power. No matter which version you use, you only need about 25% - 50% more power to achieve the design you want.

You may have heard about the growing popularity of wood laser cutters, but now is the time to try it out for yourself. These wood laser cutters and engravers promise to combine your artistic endeavors with powerful design software while saving you time, money and costly mistakes.

What are CNC wood laser cutters and engravers?
A laser wood cutter is a mechanized way of cutting and carving wood using a laser beam and design software.

Laser Engraving Ideas

These are usually carbon dioxide or gas and laser "cut" or burn the wood to create the design you want, giving you a dark burnt wood effect. During this process, the intensity of the laser is adjusted to create varying degrees of "burn," as well as product shading and contrast (if desired).

If you don't want the signature burnt brown look, there is also a way to create a white engraving when using the correct settings (i.e. low temperature and high speed).

When laser cutting wood, you need to consider a number of factors before processing, such as the density and resin content of the wood. For example, balsa wood is soft, so cutting requires less power than hardwoods such as redwood. There's also MDF (made from glulam fibers), which requires a machine that uses compressed air and a laser to optimize cutting and engraving.

Laser wood cutters are popular for making arts and crafts, but they're also great for furniture construction, interior design, gifts, models, and more. Not only do they allow you to make these things, but they make them faster and better than traditional methods, giving you more money and opportunities to create.

Wood Laser Cutting and Engraving
All of the laser cutters on our list are also capable of carving wood, depending on the setup you use. For cutting wood, you'll want a higher power setting, and less intense for engraving. With carving, you don't want to cut the wood, but burn the top layer while maintaining most of the structure.

Since wood laser engraving doesn't require power, you don't have to spend a lot of money on a solid-state laser engraver. However, if large projects and precision are priorities, it's worth checking out the advanced options.

Buying a laser engraver for your woodworking project can be overwhelming. This is especially true when there are so many machines to choose from.

First, there are different types of laser engravers, each of which will produce different results. More worryingly, not all of them are suitable for carving wood. So you may end up with the wrong machine.

Can a laser engraver engrave wood?
Yes, a laser engraver can engrave wood and do it easily. Of all the available options like Chisel, Dremel and Cricut Maker, laser engravers arguably produce the best results faster.

But in the end, the results will depend on the laser engraver and the type of wood you use. There are three main types of laser engravers to choose from.

CO2 lasers, also known as gas lasers, use carbon dioxide gas to generate a laser beam. When an electric current is passed through the gas, it emits a laser light with a wavelength of 10,000 nanometers.

This wavelength is most suitable for treating non-metallic surfaces such as leather and wood, as well as plastics.
Fiber lasers are the most powerful lasers, producing a wavelength of 1064 nanometers. These machines have the smallest focal point and can be 100 times more intense than CO2 lasers.

While fiber laser machines are popular, they are not the best for wood carving. They are designed for engraving objects with harder surfaces such as metal.

wood laser engraving machine S10 Pro
As the name suggests, UV lasers emit UV light from 10 nanometers to 400 nanometers. The wavelengths are much shorter and don't generate as much heat. Therefore, processing with UV laser is also called cold working.

These lasers are just as good at engraving materials like wood as CO2 lasers and are best for marking and even micro-marking.

So if you were to ask, "What laser can engrave wood?" the answer is all lasers, but a CO2 laser engraver is the best choice.

In addition to the above, another type of laser engraving machine is also gaining popularity. That's a diode laser. These are smaller in size and cheaper. Therefore, many laser engravers designed for home use are using diode lasers.

Atomstack a5 pro

The next factor to consider is the type of wood. While you can laser engrave on almost any wood species, the results will vary. To choose the best wood block for your project, check the following:

Streaks - Streaks are dark stains on wooden surfaces with varying mineral content. While stripes look good on wood, they are not suitable for carving. Therefore, you need to choose the wood with the fewest streaks.

Resin/Sap Content - Ideally, the wood should have a high resin or sap content. Logs with higher resin content will produce deeper burns, while logs with lower resin content will produce shallower cuts.

Tint - Logs should be lighter in tint as they will produce darker burn marks. It's much more difficult to etch designs on dark wood and get similar results.

Some wood species that meet these criteria are alder, cherry, basswood, hard maple, and balsa. I always enjoy carving other people out of these logs.

Atomstack S20 Pro
This powerful yet affordable machine meets all the requirements of a reliable wood laser engraver. It has sufficient optical power, large working area, ultra-fine focal length, and easy operation.

The short answer is yes, stainless steel can be laser engraved. It is a misconception that engraving is never suitable for stainless steel. Feasibility will depend on the application, environment and available laser engraving equipment.

atomstack p9 m40

The process of laser engraving stainless steel involves the physical removal of the surface layer of the metal by an intense laser beam to create the engraving of the desired design.

A method called deep is also commonly used to mark stainless steel. It is similar to engraving, but the material is processed multiple times. This means calibrating your machine to emit relatively low power at slower speeds, then repeating the process multiple times. When using this process on stainless steel, more material is removed to produce a cleaner engraved design.

muse 3d laser cutter P9 M40

What is the best way to mark stainless steel?
When deciding to laser engrave stainless steel, there are several ways to go about it. CO2 lasers can engrave pretreated stainless steel, or fiber lasers can engrave or etch stainless steel. Stainless steel is also suitable for laser annealing.

atomstack p7 m40

Deep laser engraving is often used to mark stainless steel. In order to obtain deeper engraving, the marking speed of the laser needs to be reduced, and the power needs to be increased. After multiple passes through the stainless steel at different angles, a clean design will result.

Another way to mark stainless steel is to anneal it. Annealing is a less invasive type of laser marking. Annealing is characterized by low power applications for extended periods of time. When you anneal stainless steel, you melt it, but you don't remove any material. This means that the chromium oxide layer remains intact and continues to prevent stainless steel from rusting or corroding.

By annealing stainless steel, you expose it to relatively low heat for extended periods of time. This process melts the material or substrate without removing the layers that protect it from oxidation or rust.

What kind of laser is needed to engrave stainless steel?
Fiber laser engravers are ideal for engraving stainless steel. A CO2 laser can also be used, but a marking solution must be applied to the surface beforehand. Many laser engraving contractors offer two laser options to achieve the customer's desired look.

atomstack a5 m40

Let's take a closer look at these two laser engraving techniques and how they perform on stainless steel.

A CO2 laser is a gas laser. Its core usually uses carbon dioxide or helium-neon gas. The older of the two methods, CO2 laser engraving is still commonly used, but operates less efficiently than fiber lasers.

CO2 laser cutters can engrave wood, plastic and metal, including stainless steel. However, CO2 lasers cannot directly engrave metal because the laser beam reflects off the surface. In order to engrave stainless steel, the material must first be pretreated with a marking solution such as CerMark or LaserBond.

This engraving style is ideal for light surface etching, including engraving stainless steel jewelry and other personalised items, as well as plaques and trophies.

Fiber laser machines are the latest development in the industry and are more efficient than CO2 lasers. Today, this is the preferred option for engraving or marking stainless steel.

Fiber lasers are more stable and very precise than CO2 lasers. Its power ranges from 4kW to 15kW or even 20kW, well above the threshold for CO2 lasers. For this reason, fiber lasers are more commonly used in industrial applications and large production runs where efficiency and speed are critical.

A laser tool can etch or cut material, these are its main functional processes. Therefore, common materials used for laser engraving include:

Glass: It is one of the top laser engraving materials. Laser work can be done on all eyeglasses for aesthetically pleasing results. It could be wine glasses, bottles, vases and cups.

Wood: It is a popular carving material because it is cheap and readily available. Other than that, you can laser engrave and cut any type of wood for different effects. The most common wood types used for carving include plywood, MDF, solid wood/solid wood, natural wood, particleboard, HDF, and veneer.

Glass etching

Marble and granite: These materials are mainly used for engraving photographs, this is because marble and granite are very effective in sculpting contrast. For a better aesthetic, use dark materials.

Bricks and Stones: They are great for carving items that will be exposed to different weather elements. This makes them ideal for engraving pieces for memorial sites and outdoor patios.

Leather: This material, like fabric, can be customized by engraving. Engraved leather is in high demand and the most common engraving materials include natural leather, suede, synthetic leather and suede.

Metals: All types of metals can be engraved, but the most common include: stainless steel, iron, steel, brass, aluminum, and silver.

Acrylic: It is a durable, reliable and lightweight alternative to glass. There are two types of acrylic sheets, extruded and cast. Therefore, they respond differently to the engraving process. Cast acrylic sheets often produce a frosted white appearance compared to the original material. Extruded acrylic, on the other hand, usually stays clear because it doesn't create as much contrast.

What machine settings are included with the laser engraver?
The laser settings determine the output of the cutter. For example, a faster speed usually indicates that the machine will have less exposure time to your material, and vice versa. The four main types of machine setups include:

1. Power
The power setting controls the energy level in the laser device. It is worth noting that as the power increases, the energy levels in the laser also increase. In general, the energy required to penetrate a material generally varies by type and thickness. Deeper cuts and vertical walls require more energy than thin tapers because more energy is required to remove more material.

NOTE: Extremely high energy levels can cause burnt edges and smoke. Overall, lower power results in straighter edges and shallower cuts. At the same time, more power results in wider edges and deeper cuts.

2. Speed
Speed ​​affects how fast the laser carriage moves. There is a direct relationship between speed and power (energy). To do this, you need to understand that the longer the exposure to an area, the more energy that area receives. Therefore, we can conclude that velocity can be used to control the duration of energy concentration at a point.

atomstack a5 pro

Lower speeds result in slower cuts but deeper cuts, while higher speeds result in faster cuts but shallower cuts because less energy is concentrated at one point in this case. Understand that your designs may end up with bad edges if you are extremely slow or too fast.

3. Frequency
Frequency settings for laser engravers are usually measured in Hertz (HZ). This decisive parameter represents the number of laser pulses generated in one second. For example, CO2 lasers have a frequency range of 1,000 Hz – 60,000 Hz.

In some cases, frequency may also be referred to as pulses per inch (PPI). It gives you ultimate control over how many times the pulse can be highlighted within a given object distance during an engraving or cutting process. Note that the higher the frequency, the more output pulses are generated. This eventually causes the pulses to overlap, resulting in a smoother cut.

However, higher frequency values ​​mean more heat is generated during the cutting process, which can cause some materials to char or melt. At the same time, the lower frequency means fewer pulses are generated in a spaced manner, which often results in perforated lines.

atomstack a10 pro

4. Key points
Focus is important to provide the best cutting results for different material thicknesses. Laser beams are required to facilitate engraving or cutting by "focusing" the light on a specific area.

To adjust the focus of the laser engraver, you will need to adjust the Z axis down depending on the thickness of the material you are using. Just measure the thickness of the material you want to engrave, and adjust the engraver's backup based on the thickness level achieved. you can focus

Laser technology has been around for a long time, enabling manufacturers to develop new ways to assemble and track their products. From welding plastics to engraving metal, lasers have a place in every industry. If you're relatively new to the technology, you might be wondering what's the difference between laser marking and laser engraving - but more importantly, which process is right for you.

Laser engraver

Laser processing method of metal
The term laser marking is often used as a word to describe a set of processes. This can range from surface marking to deep engraving, both of which leave "marks". Below are the industry standard terms we use to describe the types of tagging methods.

ablation. The terms laser engraving and laser etching are subtypes of this process, which differ by the depth of the cavity and the way light is reflected to show contrast. Laser engraving is an umbrella term for this method.

atomstack a5 20w settings
annealing. This is the surface level change of the metal to provide contrast for legibility. Laser marking is used to describe this method more generally.
Although these terms are often used interchangeably, there are differences between laser marking, laser engraving, and laser etching.

atomstack a5 pro

What is laser engraving/ablation?
Laser engraving, or ablation, is a process that involves high laser power and high-speed movement of the laser beam to rapidly vaporize material, revealing an image at eye level. This creates durable cavities in the material and is usually done before the powder coating process. Ablation can also be used to remove thin layers of materials such as paint, anodizing, and plastic films. The process called laser cleaning is a form of ablation used to remove contaminants such as rust and oil from metal, as well as to clean molds used in injection molding.

There are two main subtypes of ablation, called engraving and etching. Etching is similar to engraving, but is identified by raised edges that reflect light differently and have a shallower depth.

Engraving depths up to 0.02" and above
Etch depth typically not more than 0.001"

Sample A was engraved using an ultrafast picosecond fiber laser. The edges are clean and the surrounding material is not affected by the heat of the laser. This is called the heat affected zone (HAZ). We discussed this topic in our previous article on the unique processing capabilities of ultrafast lasers.

What is laser marking/annealing?
Laser marking or annealing is the process of modifying the surface properties of a material through an oxidation process to produce contrasting marks. This oxidation is accomplished by slowly heating the material at low power to attract carbon to the surface, creating a clear mark. This process works on steel and most plastics that contain carbon molecules. When annealed, material is not removed from the surface, resulting in a smooth finish.
