Types of Laser Engraving Machines
 

Many types of laser engraving machines are available. These engraving machines function differently, making them suited for various applications. The most common types of laser engraving machines are:

 

Fiber laser markers: A fiber laser marker is a laser engraving machine that conducts electricity using glass fibers. A laser diode creates the light and moves it along a fiber-optic cable, where it gathers energy and changes shape to fit the application. Fiber laser markers make precise markings and are extremely powerful.

 

Crystal lasers: Engraving machines with crystal lasers use garnet or vanadate crystals to change the beam’s characteristics and give it exceptionally high power. For example, vanadate laser markers provide improved beam quality and depth of focus over fiber laser markers.

 

CO2 laser markers: This laser engraving machine directs the emitted light through glass tubes containing gases like carbon dioxide (CO2), helium, nitrogen and hydrogen. These CO2 laser marking machines bounce the light between two mirrors as it grows in intensity. CO2 laser markers are versatile machines and work well with materials like plastic and wood.

 

UV laser markers: These laser engraving machines use ultraviolet (UV) light to mark materials using cold marking methods. Manufacturers can create minimal heat damage on organic materials and plastic with UV laser markers.

Laser engraving works by using a laser beam to focus a high amount of heat onto a surface to form a pattern. The super-focused laser uses concentrated heat to cut at a certain depth, removing the material’s top layer. Laser engraving machines are programmable to engrave the material with designs, including writing, numbers and patterns like logos.

 

This process owes its existence to recent advances in laser technology. The word laser is an acronym for light amplification by stimulated emission of radiation. Laser engraving machines repeatedly concentrate light beams until they reach the correct power level. The different types of laser engraving machines use varying methods to excite the electrons in the beam to generate high enough energy for the laser to cut the material. Using a laser for engraving requires three factors to operate correctly:

Concentration: Laser engraving machines must focus the wavelengths of light very close together to increase the beam’s power. The process of concentration enables the light to focus on a single point.


Energy: Once concentrated, the laser must gather enough energy to change the material’s surface from a solid to a gas, a process called sublimation. Sublimation requires extremely high temperatures to engrave the material, especially harder materials like metals.


Direction: Finally, the laser engraving machine directs the beam’s course to mark letters, numbers and designs. The laser’s movement must be precisely controlled to ensure accuracy.


Laser engraving is ideal for improved product identification and tracking. Printed product labels are easily lost or damaged, and other forms of engraving, like handstamps, can be dangerous to operate. Laser engraving makes it easier to identify and track products by permanently marking the material with a durable design that’s human- and machine-readable.

 

Materials Used in Laser Engraving Machine

Laser engraving machines are used in various applications and with different materials. From marking serial numbers on medical device parts to engraving certifications on an aerospace component, laser engraving is a highly versatile technique. Consider a few of the materials manufacturers can use laser engraving on during the production process:

 

Aluminum

Laser engraving on aluminum is prevalent in the automotive and defense industries, where manufacturers must permanently mark various components for identification. You can use many laser engraving machines on aluminum, including fiber, UV and vanadate laser markers.

 

Stainless steel

Any grade of stainless steel can be laser engraved. Various laser settings allow manufacturers to change the steel’s surface color without affecting the structural integrity. Fiber and UV laser markers are powerful enough for this material.

 

Titanium

Titanium is a popular material in the aerospace and defense industry because it’s lightweight yet incredibly sturdy. Aircraft manufacturers use titanium to construct aircraft engines and frames. You can use nearly any laser engraving machine for titanium, from fiber laser markers to UV laser engraving machines.

 

Glass

Using a laser engraving machine with glass can be a challenge since glass is a delicate material. It’s essential to use a laser engraving machine adequately suited to the task. A CO2 or UV laser marker works best with glass since these laser engraving machines operate at high speeds and prevent glass fracturing. You can carve designs on flat or curved glass workpieces using laser engraving.

 

Wood

Another popular application is laser engraving on wood. Manufacturers should know that only CO2 laser markers are safe for wood since fiber lasers can pose a fire hazard and usually create uneven marks.

 

Plastics

Many manufacturers also require permanent markings on plastic components, like parts made from acrylic and polyvinyl chloride (PVC). CO2 and UV laser markers are ideal for these applications because they prevent scratching.

 

What Is the Engraving Process on the Laser Engraving Machine

 

The laser engraving process is when the machine cuts a design into a material’s surface. Although this process can vary depending on the engraving machine, it follows a few general steps.

 

The operator enters the design
Before the laser engraving machine can engrave the material, the machine operator must enter a design into the control system. Laser engraving machines use automation and computer software to translate a design like a logo or a barcode into the laser’s movements across the material’s surface. Some laser engraving machines can store hundreds of designs, making it easier for manufacturers to achieve peak efficiency.

 

The operator places the object
After the laser engraving machine receives the design, the operator must put the material in the right place for engraving. Often, smaller materials can go into the laser tray. Larger workpieces may require a larger surface. Many laser engraving machines can be integrated into the production line for easier engraving.

 

The operator finalizes the settings
The operator ensures the final settings on the machine are correct for the material and desired engraving pattern. The laser must focus on the workpiece. Then the operator selects the desired engraving settings, including depth and beam power. These settings will depend on the material and the operator’s chosen pattern for the laser engraving.

 

The machine initiates the laser
Once the operator finalizes the machine’s settings, the machine activates the laser using software to begin engraving. The laser passes over the material throughout the engraving process, carving deep marks with a high contrast that can remain legible even under harsh conditions.

 

The material undergoes processing
After the laser completes the engraving, the operator removes the material from the machine for further processing. Sublimation creates residues like metal shards and soot after removing the top layer of the material. The material must be processed to clear this residue. Some applications might use shot blasting or heat treatment to eliminate irregularities.

 

Components of Laser Engraving Machine
