Laser Marking 101


Laser marking is a process that uses laser light to mark surfaces. The laser actually creates a line of heat on the surface that you want marked, and when the heat dissipates it leaves behind an indelible mark. This type of marking can be used in a number of applications, including industrial manufacturing, education and even entertainment. In this article we'll discuss what laser marking is and how it works so that you can decide if this technology might be right for your next project or application

What is Laser Marking?

Laser marking is a method of marking materials using a laser. The laser creates a long-lasting, clear mark on almost any material. This can be used in many different industries, including aerospace, automotive and medical device manufacturing.

Laser marking is the most precise way to mark parts with precision and high accuracy. It's also efficient—lasers use much less energy than other methods such as inkjet printing or engraving because they don't require heat or chemicals; therefore they're less expensive than these other processes too!

Laser Marking Applications

Laser marking is a versatile method of marking that can be used to mark many different materials. Laser marking has many applications, such as:

  • Marking metal, plastic and other hard surfaces with an engraved or etched image in a variety of styles and patterns. The laser beam burns into the material at a specific depth that creates an impression on the surface.

  • Making marks on wood or leather using a special pen-like device that uses heated coils inside it to melt away certain types of ink (or paint). This process is called "thermal transfer" because heat transfers through ink onto your project by melting away areas where you want it melted such as logos or text messages so they'll show up when viewed under an ultraviolet light source which makes them appear much brighter than normal paper would look like!

How Does Laser Marking Work?

Laser marking is a method of producing an image or text on materials using a laser beam. The laser beam is focused by a lens onto the material, heating it at its focal point and creating the mark in question. This process can be fully automated, meaning no hand-eye coordination is required on your part—just focus and shoot!

The most common types of lasers used for this purpose include green light (wavelengths around 400nm), blue light (around 405nm), yellowish-green or white (around 445nm), violet or red ones like helium–neon lasers which use helium atoms as their source of energy instead of chemical reactions like hydrogen atoms do when they're heated up with electric currents running through them.

What Materials Can I Mark with a Laser?

The most commonly used materials for laser marking are metals, plastics and ceramics.

  • Metals: Steel, brass, aluminum and zinc can be marked with lasers.

  • Plastics: Acrylics and polycarbonates are also commonly used in manufacturing applications because they have a high melting temperature (greater than 425°F/218°C) which allows them to be melted into a wide range of shapes before being cooled again by the laser. This property makes them ideal for making parts with complex contours such as gears or other precision-shaped components that need to be machined afterwards.

  • Ceramics: Glass is another good candidate for laser marking because it has good heat resistance when compared with other materials such as plastic or stone; however glass cannot be cut using conventional CNC machines due its lack of hardness so must either be machined manually or casted from sand molds prior

How Much Does Laser Marking Cost?

The cost of laser marking depends on a variety of factors, including the size and complexity of your design, as well as how many marks you want to make. You can expect to pay more for larger areas or more complex designs because these require more time and equipment.

The cost also varies depending on whether you're using an industrial laser or a consumer model such as those sold at Office Depot and other office supply stores. Industrial models tend to be more expensive than consumer ones because they have longer lifetime spans (upwards of 10 years), higher power outputs (upwards of 20 watts), better beam quality (more precise), faster speed settings (from 5-10 seconds per mark), etc., so they may cost $1-$2 per inch while consumer models run around 50 cents per inch!

The Benefits of Using a Laser Marker

Laser marking is a fast and accurate process that can be used to mark a wide variety of materials. It can be used to create high quality markings, such as logos, letters and numbers on leather, fabric and more. Laser marking also allows you to make permanent impressions of your design into the surface of your material so it will last longer and look better over time.

Laser markers are environmentally friendly because they use no paint or chemicals; they only require electricity! They're also cost effective because there's no need for expensive machines; all you need is an electric outlet in order to use them!

Laser marking can be used to create long-lasting, clear marks on almost any material.

Laser marking is a process that uses a laser to burn an image into a material. This can be used for identification and branding, but it's important to note that lasers have limitations: they're only effective on certain materials, such as plastics and metals.

Lasers can also be used on non-precious materials like wood or leather—and they create permanent marks that are visible up close. However, lasers aren't indestructible; if your logo gets damaged by water or other liquids (like rain), it will need replacing before you use the device again!


As you can see, laser marking offers many advantages over other methods of marking. It’s fast and easy to use, which makes it perfect for spot-checking or verifying that parts fit properly before they leave the shop floor. Plus, it creates a durable mark on materials like metal or plastic that cannot be done by hand or with inkjet printers alone—that means less time spent fixing mistakes later down the road!
