What Is Plastic Laser Engraving?
Plastic laser engraving is the process of using a high-intensity laser beam to etch patterns, text, or designs onto the surface of plastic materials. Unlike mechanical engraving, laser engraving is contactless, which makes it ideal for delicate or thin plastics that could be damaged by traditional tools.
Using a laser engraver, you can achieve:
- Crisp lettering and barcodes
- Custom logos
- Fine line artwork
- Even full grayscale images with the right settings
The laser’s settings—speed, power, frequency, and focus—can be adjusted based on the type of plastic and the level of detail you want to achieve.
What Types of Plastic Can You Laser Engrave?
Here are some plastics commonly used for laser engraving:
| Plastic Type | Engraving Suitability | Notes |
|---|---|---|
| Acrylic (PMMA) | ✅ Excellent | Clean edges, great for signage |
| ABS | ✅ Good | Watch for melting or warping |
| Polycarbonate (PC) | ⚠️ Limited | May discolor; test first |
| Polyethylene (PE) | ⚠️ Limited | Soft surface, prone to distortion |
| PVC | ❌ Avoid | Releases toxic chlorine gas |
| PET (Polyester) | ✅ Good | Thin sheets engrave well |
| Delrin (Acetal) | ✅ Excellent | Crisp results, ideal for industrial parts |
| HDPE / LDPE | ⚠️ Limited | May melt or smoke excessively |
💡 Pro Tip: Always verify if your plastic is laser-safe. Avoid PVC and materials with unknown coatings. If unsure, consult the manufacturer or test a small piece first.

Step-by-Step: How to Laser Engrave a Plastic Card
Here’s a beginner-friendly walkthrough to laser engrave a colored plastic card:
Step 1: Choose Your Plastic
Select a laser-safe plastic like acrylic or ABS. Use flat, smooth blanks for consistent results.

Step 3: Set Up the Machine
- Power: Start at 20–40% for UV; 40–60% for fiber
- Speed: 300–800 mm/s depending on plastic
- Focus: Use auto-focus if available, or a spacing gauge
- Test Run: Always run a preview pass before full engraving
Step 4: Safety First
Plastic engraving can release fumes. Always:
