5 Useful Tips on Acrylic Laser Engraving

Laser engraving is used to engrave permanent marks on a variety of materials. A laser engraving machine vaporises a specific area of the desired part or material in a given pattern created by lasers, such as CO2 or fibre lasers, in this process. When it comes to engraving materials, acrylic is a great choice for its durability and versatility.

It can withstand both indoor and outdoor elements without fading or cracking, making it ideal for signs and labels. Acrylic can also be easily cut into various shapes and thicknesses, giving engravers the ability to create unique designs. Another advantage of using acrylic is that it can be translucent or opaque, offering a range of possibilities for lighting effects.

In addition, acrylic comes in a variety of colours and finishes, allowing for even more customisation. Whether you’re creating custom merchandise or personalised gifts, here are some tips to keep in mind when using a laser engraver on acrylic.

1. Clean and Dry the Surface Before Laser Engraving

Any dirt or moisture on the surface can cause laser marks to appear uneven or blurred. For best results, use a lint-free cloth to wipe away any dust or debris before beginning the engraving process. In addition, make sure that the laser acrylic is kept in a cool and dry environment during storage to prevent condensation from forming on the surface.

2. Use the Correct Settings

When laser engraving acrylic, it’s important to set the laser power, speed, and frequency correctly. The correct settings will depend on the thickness and type of acrylic being used. Engraving at too high a power can cause the acrylic to melt or crack, while engraving at too low a power can result in a weak engraving. 

The speed should also be adjusted depending on the intricacy of the design, as engraving too quickly can result in blunt edges. Finally, adjusting the frequency can affect how deeply the laser cuts into the acrylic and create different aesthetics for your engraving. By carefully adjusting these laser engraving settings, you can achieve professional quality results with your acrylic projects.

3. Make Sure the Material is Secure

Acrylic can easily crack or melt if it shifts while being laser engraved due to the intense heat generated by the laser beam. To prevent this, use a clamp or double-sided tape to firmly hold down the acrylic sheet on the engraving bed. Additionally, consider using a jig or stencil to keep all engravings in a consistent position and avoid any shifting of the material during the engraving process.

4. Do a Trial Run on Scrap Acrylic

When laser engraving an acrylic sheet, it’s always a good idea to do a trial run first. This allows you to adjust settings and ensure the laser is properly calibrated for the specific acrylic sheet you are using. Using scrap acrylic or a small section of the sheet you want to engrave can help prevent any mistakes or mishaps when it comes time for the real deal. 

It’s better to spend a little extra time and effort in this trial phase than to potentially ruin an important piece due to technical errors. Plus, experimenting with the laser settings on scrap material can also give you some room to play around and get creative with your designs.
