Getting Started with Laser Engraving

Laser engraving is an exciting and versatile craft that allows you to create intricate and personalized designs on various materials. Whether you’re looking to start a small business or simply want to explore a new hobby, laser engraving offers endless possibilities for creativity and innovation.

In this section, we’ll dive into the basics of laser engraving, its benefits, and the differences between laser cutting and laser engraving.

What is Laser Engraving?

Laser engraving, also known as laser etching, is a process that uses a high-energy laser beam to engrave designs onto various materials, such as wood, acrylic, and metal. The laser machines, including diode lasers, CO2 lasers, and fiber lasers, emit a focused beam of light that vaporizes the material’s surface, creating a permanent mark or design.

Laser engraving machines can create intricate patterns, text, or images with incredible detail and accuracy, making them a popular choice for personalization and customization projects.

While laser cutting and laser engraving may seem similar, they serve different purposes and have distinct processes. Laser cutting involves using a laser beam to cut through materials, creating an entirely separate piece or a desired shape, as you can see in the image above. On the other hand, laser engraving uses the laser beam to mark or etch the surface of a material, creating a design without cutting through the material.

Both processes have their unique advantages and applications, with laser cutting being ideal for creating parts and components, while laser engraving is perfect for customizing items.

The Difference Between Laser Engraving and Laser Etching

Laser engraving and laser etching are very similar – they’re both methods of marking the surface of a material using a laser beam. However, they operate on different principles and produce distinct results.

Laser engraving is a process where the laser beam removes a portion of the material’s surface to create a design or mark. This process is characterized by the vaporization of the material, resulting in a noticeable cavity on the surface.

The depth of the engraving can vary depending on the laser’s power and the material in question. Laser-engraved designs are typically more durable and can withstand wear and tear, making them ideal for applications where longevity is crucial.

On the other hand, laser etching is a subset of laser engraving, but it only removes a thin layer from the surface of the material. Instead of vaporizing the material to create a deep cavity, laser etching merely melts the surface, causing it to expand and create a raised mark, as you can see in the image above.

This process results in a change in the material’s texture and often its reflectivity, producing a contrasting mark that is easily visible. Since the alteration is only on the surface level, laser-etched designs might be less durable than engraved ones, especially under conditions of heavy wear. However, etching is particularly useful for applications that require fine, detailed markings or when working with very thin materials.

Choosing the Right Laser Engraver for Beginners

As a beginner, selecting the right laser engraver can be a daunting task. There are several factors to consider, such as:

  • Your budget

  • The ease of use and assembly of the machine

  • What kinds of materials do you want to engrave

  • How large of pieces you want to work on

  • Portability

  • The compatibility of the engraver with different design software

In this section, we will provide guidance on choosing the perfect laser engraver for beginners, ensuring that you start your laser engraving journey with confidence.

Budget Considerations

When selecting a laser engraver, it’s essential to consider your budget. While there are high-end laser engravers with advanced features, beginners can find affordable and reliable options that still offer excellent engraving quality.

A cheap laser engraver, such as a diode laser engraver, is a cost-effective choice for those new to the craft, with entry-level machines priced under $300 and higher quality machines going up to about $2,000. Diode laser engravers can engrave most materials, and they can also cut through materials, but generally only to thicknesses of a few millimeters.

CO2 lasers are more expensive than Diode lasers and usually offer a higher capability in terms of what they can cut. If you’re looking to laser cut thicker materials, even 1/8 or 1/4 of an inch, a CO2 laser is your best bet. For Engraving, however, CO2 and Diode lasers are pretty similar in terms of materials.

Fiber lasers are another good option if you don’t have a large budget. For example, the LaserPecker Pro Engraver Mini is just $319. They are great for engraving on most materials; however, if you ever want to do laser cutting as well, fiber lasers are not a good option.

Keep in mind that additional accessories, such as protective gear and ventilation systems, may also be necessary, so factor these costs into your budget as well.

Additionally, consider selecting a laser engraver with an enclosed housing and light-filtering lid, as these features provide added safety and protection during the engraving process using a laser cutter.

Another thing to consider in this section is alignment. CO2 lasers have a network of mirrors that direct the laser beam to the cutting head, and these need to be aligned on a regular base. Diode and Fiber lasers, however, do not need to be aligned.

Materials

Laser plywood

There are a standard set of materials that all types of lasers can engrave onto, including plywood, solid wood, acrylic, paper, leather, steel, glass, and ceramics, to name a few. Most engravers can also cut these materials and more, like foam.

If you want to work on other types of metals, like stainless steel or aluminum, you’ll want to ensure your machine can work with these before purchasing. For a full list of lasers that can engrave onto metal, see our comprehensive guide here.

Work Area Size

Size matters when it comes to laser engravers and laser cutting. Most Diode laser engravers, for example, have a work area of about 16″ x 16″. You may be able to get creative by placing the laser in different positions on top of a large flat piece, but it will get complicated quickly trying to align patterns.

Fiber lasers are even smaller, with most work areas being about 4″ x 4″. Use these if you only plan to work on small projects.

CO2 lasers have the largest work areas, with reasonably priced machines having a work area of around 20″ x 12″. If you want to work on projects bigger than this, consider a CO2 machine that has a pass-through feature, allowing material of any length to stick out a door in the machine while you engrave it.

Understanding and mastering the settings of your laser engraver is crucial for achieving the best results. In this section, we’ll discuss the importance of power, speed, and resolution settings and how they impact the quality of your engravings.

Power settings determine the amount of energy that is used to cut or engrave the material.

Power Settings

Laser cutter settings

Power settings play a vital role in the laser engraving process, as they determine the intensity of the laser beam projected onto the workpiece. Higher power settings result in deeper and more intricate engravings, while lower power settings produce shallower and less precise engravings.

It’s essential to adjust the power settings according to the material being engraved and the desired outcome of the engraving.

One thing that was confusing when I was starting out is the different types of power that you will see referenced for laser machines:

  • Machine power

  • Laser electric power

  • Optical or output power

Machine power is simply the input power of the machine and is not relevant for beginners.

Laser electric power is the electrical energy that goes into the laser module and is also not relevant for beginners.

What you do want to pay attention to is the optical or output power of the machine. This is what will help you understand the engraving and cutting capability of the laser cutter. It’s important to pay close attention to what power is being advertised by a company because sometimes they may intentionally mislead you by stating electrical power instead of optical power (electrical power will always be higher than optical power).

Diode lasers typically have an optical power between 5-15W. CO2 lasers are generally power powerful than Diode lasers, with an optical power range of 40W to 300W. Fiber lasers are the most powerful (they can cut through metals) and can have an optical power of up to 4,000W for consumer machines, and industrial fiber lasers can have a power of up to 12,000W!

Speed Settings

The speed at which the laser head moves across the material during the engraving process also impacts the depth and contrast of the engraving. Slower speeds yield deeper engravings with increased contrast, while faster speeds produce shallower engravings with reduced contrast.

Adjusting the speed settings according to the material and desired engraving result will ensure optimal outcomes.

The more optical power your machine has, the faster it can go while achieving the same results.

Resolution and DPI

Resolution and DPI (dots per inch) settings affect the detail and precision of your laser engravings. A higher resolution and DPI result in finer details and smoother edges, whereas a lower resolution and DPI can cause pixelation and loss of detail.

Understanding and adjusting the resolution and DPI settings according to your engraving design will help you achieve detailed and precise engravings.

Executing Your First Laser Engraving Project

Now that you have a solid understanding of laser engraving, it’s time to put that knowledge into practice and execute your first laser engraving project.
