Achieve Perfection: Avoiding the Most Common Laser Etching Mistakes

The great news: thanks to decades of developments, today’s laser machines have become so streamlined and user-friendly kids as young as ten can use them and get great results. But the bad news: expertise in laser etching still takes time and practice, and the process of trial and error can be frustrating. Helping you learn the proper use of a laser etching machine so that you can produce a great product is very important to us, so here are some of the most common mistakes in laser etching, as well as some ways you can avoid them:

Mistake #1 Expecting the Same Results on the Same Material

One of the most laser-friendly materials is wood. It can be etched easily, but various types of wood can react differently when they’re laser-etched.

Grain density can make or break the outcome of your etching. The type of wood you’re working with can suddenly change the grain density. For instance, lighter types of wood, like cherry or maple, can create a visual contrast where the laser burns away wood. Denser woods, on the other hand, need more laser power to etch.

Cherry, maple, walnut, and alder have tiny veins of grain in them. Laser-etch a large square into a piece of cherry and the result would be a uniform appearance. The etched area will be smooth with slight variations in height. Oak, on the other hand, has medium to large veins. So laser-etch the same square into a piece of oak and the result might leave you with a non-uniform appearance. You’ll also notice great variations in height between the different wood.

Mistake #2 Low-Quality Glass Engravings

When the laser strikes glass, it often fractures the material’s surface but doesn’t engrave the material correctly. Although the fractured surface creates a frosted appearance, it can be rough or chipped, depending on the type of glass, which isn’t the desired result.
Instead of settling for a chipped product or one with a rough finish, take note of these suggestions to produce a smooth, beautiful outcome:

  • Apply a wet, thin sheet of paper towel or newspaper on the engraving area to help dissipate heat and enhance the etching process. Just make sure that the paper has no wrinkles. Alternatively, you can dissipate heat by applying liquid dish soap.
  • Use a lower resolution, preferably around 300 dots per inch (DPI). This lets you produce a better result on the glass.
  • If you find shards of glass after the engraving process, polish them with a non-scratch scouring pad.

Mistake #3 Poor Results with Fabric

Not all fabrics can withstand high laser settings during engraving. So take extra care when working with delicate fabrics to prevent burning holes in them. One method: configure your laser machine at low power (around five to 10 percent), and high speed (near or at 100 percent) when working with a piece of fabric. Test these settings on a spare material to determine if your fabric can withstand the heat.

If you’re doing direct-to-garment engraving, decrease the DPI by setting it anywhere from 150 to 300. Etching at a lower DPI allows you to vaporize only the top layer of the fabric.

Mistake #4 Poor Overall Laser Etching Machine Performance

If your laser etching machine is performing poorly overall, this may be a sign it’s time to clean it. Like all kinds of design equipment, your laser etching machine needs regular maintenance.

A clean machine will produce better results. You can rely on your laser machine user manual to see its maintenance requirements. As soon as you notice the performance of your machine slipping, checking and cleaning the optics may be the initial step to resolve the issue. Here are some tips for handling the optics of your device:

  • Try to inspect the optics in the laser — the lenses and mirrors — every week
  • Clean them as much as possible; smudges or debris will affect your machine’s performance very quickly
  • Look for wood or acrylic residue in the machine and immediately remove
  • Remove any dirt right after using the laser etching machine

But by far the best way to ensure you’re getting the most out of a laser machine:
