3D Laser Engraving Acrylic
Subsurface 3D laser engraving in acrylic offers endless possibilities across various industries. From personalized gifts to professional awards, the depth and clarity achieved through this technique make it a favored choice for creating memorable and striking pieces.
What is 3D Laser Engraving?
3D laser engraving is a specialized process that creates intricate designs within solid materials such as acrylic, crystal, and glass. This technique uses a high-powered laser to etch detailed images or text beneath the surface of these materials, resulting in a stunning three-dimensional effect.
Acrylic:
When laser engraving in acrylic, the laser creates precise, layered cuts that reflect light beautifully.
The result is vibrant, colorful designs that can be illuminated from behind, enhancing the visual impact.
Crystal:
In crystal, the laser etches fine details, capturing depth and clarity.
The engravings can appear to float within the crystal, creating a captivating visual experience that changes with the angle of light.
Glass:
For glass, the laser can create smooth, detailed images that are durable and resistant to fading. The engravings can be subtle or bold, depending on the intensity and settings of the laser.
What is the Best Acrylic for 3D Laser Engraving?
When selecting acrylic for subsurface 3D laser engraving, choosing high-quality materials is essential to achieve the best results. Here are some of the top acrylic options along with their characteristics:
3D Laser Engraving Acrylic
Plexiglass®:
Transparency: Excellent (up to 92% light transmission)
Grade: Premium Quality
Pricing: Moderate to High, typically $30–$100 per sheet depending on thickness and size
Notes: Known for its clarity and durability, Plexiglass® provides vibrant colors when illuminated and is ideal for detailed engravings.
Cast Acrylic:
Transparency: Excellent (up to 92% light transmission)
Grade: High Quality
Pricing: Moderate, usually $25–$80 per sheet
Notes: Cast acrylic is thicker and more robust than extruded acrylic, making it ideal for deep engravings. It provides a smooth finish that enhances light diffusion.
Extruded Acrylic:
Transparency: Good (about 90% light transmission)
Grade: Standard Quality
Pricing: Lower, typically $20–$50 per sheet
Notes: While not as clear as cast acrylic, extruded acrylic is easier to work with and more affordable. It’s suitable for engravings, but results may NOT be as striking as with cast acrylic.
Optical Acrylic:
Transparency: Excellent (Similar to Glass)
Grade: High-Grade
Pricing: Higher, around $50–$150 per sheet
Notes: Designed for high-performance applications, optical acrylic offers superior clarity and is perfect for professional-grade engravings.
For the best results in subsurface 3D laser engraving, cast acrylic like Acrylite® is often recommended due to its superior clarity and engraving quality. However, Plexiglass® is also an excellent choice for those seeking durability and vibrancy.
Consider your budget and the desired outcome when selecting the right acrylic for your project.

FAQ: 3D Laser Engraving Acrylic
1. Can You Laser Engrave on Acrylic?
Yes, you can laser engrave on acrylic!
Choose the Right Type: Use cast acrylic for deeper, more detailed engravings. Extruded acrylic is easier to work with but may not provide the same depth.
Settings Matter: Adjust the laser settings based on the thickness of the acrylic. Lower speeds and higher power settings generally yield better results for deeper engravings.
Test First: Before working on your final piece, do a test engraving on a scrap piece of acrylic. This will help you fine-tune settings for optimal results.
Protect the Surface: Use a masking tape or protective film on the surface of the acrylic before engraving to prevent scratches and ensure cleaner edges.
Ventilation is Key: Make sure your workspace is well-ventilated. Acrylic can emit fumes when laser cut or engraved, so using a fume extractor is recommended.
Post-Processing: After engraving, clean the piece with mild soap and water to remove any residue, which can enhance the clarity of the engraving.
2. Is Plexiglass Safe to Laser Engrave?
Yes, Plexiglass IS SAFE to laser engrave, but there are some important distinctions to consider:
Acrylic vs. Plexiglass: Plexiglass is a brand name for a type of acrylic. Both materials are similar, but Plexiglass typically refers to high-quality cast acrylic, known for its clarity and durability.
Fume Emission: When laser engraving Plexiglass, it can emit fumes similar to standard acrylic. Ensure your workspace is well-ventilated and use a fume extractor to mitigate any health risks.
Thickness and Quality: Higher-quality Plexiglass allows for cleaner cuts and engravings. Opt for thicker sheets (at least 1/8 inch) for more substantial engravings.
Laser Settings: Just like with regular acrylic, ensure you adjust your laser speed and power settings appropriately. This will help prevent burning and achieve a smooth finish.
Finishing Touches: After engraving, you can polish Plexiglass with a plastic polish to enhance clarity and shine, making the engraving stand out even more.
