Part 1: What is Acrylic Laser Engraving?

Acrylic laser engraving is a precise process that uses a focused laser beam to engrave designs, text, or artwork onto acrylic surfaces. Laser engraving acrylic offers unparalleled precision, making it a popular choice for both artistic and professional applications.

Compared with other acrylic engraving methods, engraving acrylic with laser is always the superior choice as it offers convenient, precise and durable engraving on various types of acrylic, providing intricate designs with lasting quality.

Part 2: What Type of Acrylic is Suitable for Laser Engraving?

When it comes to the type of acrylic, cast acrylic is usually the first choice for laser engraving due to its clear quality and minimal stress, resulting in precise engravings. On the other hand, extruded acrylic, while less expensive, may have less clarity and more stress, making it better suited for acrylic laser cutting to achieve cleaner edges.

In terms of color, darker opaque acrylic sheets are typically easier to laser engrave and cut than lighter colors.

Items Required for Acrylic Lamp Laser Engraving:

• Engraving Material: Acrylic Sheet
• Engraving Machine: Diode Laser Engraver
• Engraving Helper: Marker pen

① Acrylic Sheet

Selecting the right acrylic material for laser engraving is crucial for achieving desired results. Acrylic materials with smooth, clear surfaces are excellent options. In addition, it's important to choose laser-safe acrylic sheet to avoid any potential safety hazards.

In this guide, we'll conduct a case study on laser engraving with a acrylic sheet!

② Marker pen

Since transparent or translucent acrylic won't absorb the light of diode lasers, how do you prepare clear acrylic for laser engraving?

Actually, it is quite simple. To do laser engraving on clear acrylic, you need a marker to blacken the surface of acrylic material to form a coating and then wipe away the excessive marks when finishing the engraving progress.

In this case study, using a marker pen proves to be the optimal choice. Apart from that, The color of the marker pen is critical, as it will be permanently transferred to the acrylic. Darker colors are more effective because they absorb the laser light efficiently, while lighter colors can be more challenging because they tend to absorb less light from the laser.

③ Acrylic Laser Engraving Machine (LP2 VS LP4)

Different laser engraving machines cater to varied custom acrylic engraving scenarios. For instance, machines like LaserPecker 2 (LP2) are designed for laser engraving on materials such as acrylic, plastic, stained glass, and ceramics.

LaserPecker 2 (LP2) - Portable and Handleable Laser Engraver

In addition to the LP2, another excellent option for acrylic laser engraving is the LaserPecker 4 (LP4). This versatile machine not only provides comprehensive laser engraving capabilities but also extends to laser cutting.

Furthermore, the choice of machine significantly influences the precision, clarity, and speed of the laser engraving process. Taking the example of LaserPecker 2 (LP2), it boasts an engraving accuracy of 0.05mm, a resolution of 2k, and an engraving speed of 600 mm/s. In contrast, LaserPecker 4 (LP4) excels with a higher precision of 0.003mm, an impressive 8k resolution, and a faster engraving speed of 2000 mm/s.

Other Features of LaserPecker 4

• Dual-Laser Capability: The LP4 features dual lasers, providing flexibility to tailor your choices based on scene requirements.
• Enhanced Material Compatibility: LP4 is compatible with a wide range of materials, including acrylic, silver, gold, copper, brass, silicone, rubber, crystal, stone, metal, wood, plastic, leather, and more.

So, to do acrylic laser engraving, Machine like LaserPecker 2 (LP2) is a good choice. If you pursue better engraving experience and more usage scenarios, you can try machine like LaserPecker 4 (LP4).

Before engraving acrylic with a laser engraver, the last concern is What wattage laser is appropriate to engrave acrylic? In fact, a 5-watt diode laser engraver is sufficient for the task.

Here, we opt for the LaserPecker 2 (LP2) to laser engrave acrylic lamp.

Step 1: Choose Acrylic Sheet

Both clear and non-transparent acrylics are okay for LP2. To engraving on non-transparent acrylic, one more step you need to do is to paint the surface with a black marker, which will effectively block the transmission of light through the acrylic.

Step 2: Prepare Your Design

Regardless of what you're engraving on, image preparation is important. Your image should be sized to match your material. Afterwards, you can use software like Adobe Illustrator to create your own design, or find pre-made designs online.

The LaserPecker graphic design app & software also provides default patterns or a design space for your creation, it also supports you to upload your own high-resolution pictures with various formats.

Then, open the LaserPecker graphic design software and load your design.

Step 3: Adjust Machine for Engraving

In this step, you need to place your acrylic plate into the working area and set the focal length by putting down the L-shaped ruler to touch the surface of acrylic plate (or just measure the 11cm distance between machine and plate surface).

Finally, Access the software's laser settings to adjust parameters like power, speed, and resolution according to the acrylic's properties and design intricacy. You might be wondering, "How much laser power is needed to engrave acrylic material?" and "What is the best laser setting for acrylic engraving?" Rest assured, I've got you covered!

To get the best result, the recommended laserpecker 2 material settings for acrylic is 5 W 450 nm; Resolution: 2k; Power: 100%; Depth: 15%; Pass: 1

To explore other recommended laserpecker engraving and cutting parameters, refer to the settings table that applies to any laserpecker machines, including LP1, LP2, LP3, LP4 and LX1.

Step 4: Engrave Your Acrylic Now

Double-check everything to avoid mistakes. Then, hit the start button and watch the magic happen. The laser brings your design to life. Keep an eye on it, and you're all set!

When operating a laser engraving and cutting machine with a 450 nm blue laser, it's advisable to wear goggles or use a laser protection cover to protect your eyes and body from potential harm, as the blue laser can pose risks.
