6 Tips when Acrylic Laser Engraving for Beginners


1. Choose the Right Acrylic for Engraving


The first step in acrylic laser engraving is selecting the right type of acrylic. Acrylic sheets come in various colours, thicknesses, and types. Here are some factors to consider:


Transparency: Transparent or clear acrylic works well for engraving, as it allows the laser to penetrate the material effectively. However, you can also engrave on coloured or opaque acrylic for unique effects.


Thickness: The thickness of the acrylic sheet impacts the engraving depth. Thicker sheets can produce more profound engravings, but they may require more laser power. 3mm Cast Acrylic is the most commonly used for engraving.


Cast vs. Extruded: Cast acrylic is preferable for laser engraving because it engraves more uniformly and produces fewer fumes. It's a bit more expensive than extruded acrylic but worth the investment for quality results.


2. Safety Precaution when Laser Engraving


Before you start engraving, it's crucial to ensure your safety and the safety of those around you. Laser engraving involves high-intensity light and heat, so here's what you need to keep in mind:


Wear Appropriate Safety Gear: Safety goggles designed for laser work are a must. They protect your eyes from harmful laser radiation. Avoid looking into the laser when it is working. If you need to watch your laser working, use safety goggles or look at it through a second screen (ei: recording on phone). Masks and respirators are also recommend to minimize inhaling engraved dust.


Ventilation: Ensure your workspace is well-ventilated to disperse any fumes and smoke produced during engraving. Engraving acrylic creates a lot of harmful dust and it is recommended to have a venting system with filter and an air purifier for your working area. Clean/ replace your air filter once full.


Fire Safety: Have a fire extinguisher on hand and be mindful of flammable materials around your workspace. Supervise your laser machine when working and clean your machine regularly and keep your working area free from debris and dust to minimize any fire risk.




3. Engraving Your Design


Once you've chosen your acrylic and taken safety precautions, it's time to prepare your design for Engraving. Engraving can be done in both .svg and .png/.jpg format.


Vector Graphics: Use vector design software like Adobe Illustrator or CorelDRAW to create your design. Vector graphics are scalable and provide precise results for your engraving and is the best choice when engraving logos, word mark, graphics etc.


Resolution and Scaling: Ensure your design is high-resolution and correctly scaled to fit the acrylic sheet. Avoid engraving detailed photographs on acrylic.


Adjust Settings: Familiarize yourself with the settings on your laser engraving machine. You'll need to set the power, speed, and frequency for your specific acrylic and design.


Test Cuts: Before engraving your final design, perform test cuts on scrap pieces of acrylic to fine-tune your settings and ensure the desired result.


4. Set up your Acrylic Sheet for Engraving


To prevent the acrylic from moving during engraving, you must secure it properly. Here are some tips:


Use a Honeycomb Bed: A honeycomb bed is an ideal platform for laser engraving. It minimizes the surface area in contact with the acrylic, reducing the chance of damage.


Tape or Masking: If your acrylic comes with plastic masking or no masking, remove and reapply with masking tape or masking paper prior engraving your acrylics. Ensure your masking tape/ paper is applied smoothly without wrinkles or overlapping as this will affect the laser burning power and leave your engraving bumpy. This will leave your acrylic with clean cut edges, avoid scorch marks and easy clean up for painting your engravings.


Use Fixtures: For precise alignment with pre-cut acrylic sheets, use fixtures or jigs to hold the acrylic in place. This is particularly useful for engraving multiple pieces with the same design.



5. Check your Laser Engraving Settings


Now that your acrylic is prepared and secured, it's time to start the engraving process.


Focus the Laser: Ensure the laser is correctly focused on the acrylic surface. Most laser engraving machines have a built-in focus tool.


Start Slow: Begin with lower power and slower speed settings, then gradually increase them until you achieve the desired result. This helps prevent overburning.


Multiple Passes: For deeper engravings, consider multiple passes with reduced power and increased speed. This minimizes heat build-up and produces cleaner results.

6. Clean up your Laser Engraving


Once your engraving is complete, there are some post-processing steps to ensure your work looks its best:


Remove Masking: Carefully peel off the masking tape from the acrylic cut starting from the corner. If you have some trouble lifting the small details in between the engravings, use a plastic scrapers to lift the masking paper off. Masking should be left on if you want to paint your engraved designs.


Clean the Surface: Use a soft cloth or a gentle cleaning solution to wipe away any acrylic dust residue from the engraving. Cleaning your surface is a must when you paint your engraving as the dust will make your paint appear bumpy and creates air bubbles in your paint.



Common Mistakes when Laser Engraving Acrylic'


As a beginner, you might encounter some common mistakes when acrylic laser engraving. Here's how to avoid them:


Inadequate Test Engraving: Skipping test engraving can lead to wasted time and materials. Always test engrave your settings on scrap acrylic before working on your final piece. Take a log of your settings when you are happy with the result to reference back to when needed.


Not following Safety Precautions: Never compromise on safety. Wearing protective gear and having the right safety practice is non-negotiable when it comes to working with laser. Your health and safety are important too.


Poor Design Preparation: A well-prepared design ensures a successful engraving. Check for spelling errors, scaling issues, and any other design problems before starting. Offer redesign service for clients when only low quality images are provide. This service will make you stand out to your competitors in terms of quality.
