Laser technology has significantly impacted many industries and can be used for many applications. Laser engraving is one of the outstanding practices many companies and individuals are investing in these days. This is a practice that involves using lasers to engrave an object.

A fiber laser engraver works in simple criteria whereby a laser beam is used to change an object’s surface by exposing a lot of heat to it. Depending on how long the beam exposure time, the object changes color and creates a contrast. The end-product of laser engraving is a permanent and very resistant piece.

Laser engraving is widely used to create images on different materials. You can also use the technology to mark the surface of an item. Therefore, laser engraving is an incredible process, and it’s better than mechanical engraving, and this is why:

  • Wide field of application

A laser beam is a universal tool you can use in many materials, and it’s excellent for use in many industrial applications.

  • Non-contact material processing

Laser processing doesn’t involve a lot of work, such as having your material clamped with a vacuum and end up damaging it if something goes wrong. The laser engraving process is contactless, and no chips are produced, and there is less dust.

  • Maximum precision and finest details

The laser technology is accurate and will implement the finest motifs with high-level precision.

  • Economic production

The entire process is cost-effective and economically realistic as you can produce as many pieces without tool wear.

Materials to Laser Engrave- Everything to Know

If you settle for a fiber laser engraver for all your projects, don’t just focus on the work you can do. It’s imperative to also keep in mind the different materials you can engrave. They include:


Laser engraving metals is possible, and the results are highly precise and outstanding. Operating a laser engraver is not that daunting. You just need the right training and skillsets. You will successfully make clean, accurate marks and engravings on the metal of choice within no time.

Some of the metal surfaces you can easily engrave with your fiber laser include:

  • Aluminum
  • Stainless steel
  • Titanium
  • Brass
  • Copper
  • Tungsten
  • Carbides
  • Alloyed steels
  • Anodized aluminum
  • Coated metals
  • Nickel-plated materials
  • Galvanized materials
  • Hardened metals
  • Precious metals such as silver and gold

Fiber laser engraving makes it easy to make marks on metals covered with paint. You will get precise results and engrave at high speed, saving more time and resources. Using the MOPA technology, you can engrave 16 to 32 different colors.


Engraving plastics with laser technology can be a complicated process if you don’t know where to start. There are different types of plastics you can engrave and vary in their densities and mixes. Fiber lasers are the best choice if you want to engrave at high speed and some specific plastic materials.

Some of the most common plastic for engraving include ABS, PLT, PS, and PBT. Laser engraving of plastics has impacted the automotive industry, medical devices, rapid prototyping, and printed circuits.


Fiberglass is a common type of fiber-reinforced plastic. It’s possible to laser engrave fiberglass but with limitations. This will involve using a blur effect if the material is not a cover for a painting or another element that can recover the surface.

You have to make sure the fiber laser engravers don’t threaten the structural integrity of the material. Fiberglass is made up of individual fibers you don’t want to damage with a laser beam.

Carbon Fiber

Carbon fiber is easy to engrave as a laser beam won’t threaten the integrity of the material. However, the contrast or composition of the material will change, resulting in a black laser mark. These changes will limit readability and contrast.

Synthetic Leathers

You can also engrave materials rick in plastic polymers but at high speed and with low power.

Invest in the Best Fiber Laser Engraver

With a clear understanding of the many materials you can fiber laser engrave, it’s wise to invest in the best laser engraver. In your pursuits, look no further than Shenzhen JPT Opto-electronics Co., Ltd. The company is widely reputed for researching, developing, manufacturing, and distributing fiber lasers and optics.

JPT produces intelligent spectrum detection lasers, smart equipment, and optical devices. The company manufactures and markets its lasers and other equipment in Asia, Europe, North America, and other parts of the world. The good news? It’s not that daunting to choose a JPT laser engraver.

Know the type of fiber laser you need and one that will guarantee optimal results in your applications. You can decide to go for a Thulium-doped fiber laser, Erbium-doped fiber laser, or Ytterbium-doped fiber laser, or any other available type.
