Acrylic engraving is a go-to method for creating crisp, professional-looking signage, gifts, promotional pieces, and decorative projects. This guide keeps the original “Mega CO2 laser + acrylic engraving” intent, but updates it to Monport’s current promoted desktop model: Mega S—built around speed, precision, and workflow efficiency.

Why Mega S is an excellent choice for acrylic engraving
Acrylic rewards stable motion, clean airflow, and repeatable focus. Mega S is positioned for these real-world needs with a 70W CO2 power class, a large working space, and production-friendly workflow features that help you go from setup to finished acrylic pieces faster.
- Speed & productivity: designed for high-throughput workflows and repeat runs.
- Large working space: easier batching for coasters, keychains, plaques, and signage layouts.
- Cleaner results: airflow/exhaust design helps manage acrylic smoke and residue.

Best starter settings for acrylic engraving (use a test grid first)
Acrylic types vary (cast vs. extruded, clear vs. colored, glossy vs. matte), so the fastest path to perfect results is a small test grid on a scrap piece of the same acrylic. Use these as practical starting ranges:
- Power (engraving): 30%–40%
- Speed (engraving): 200–300 mm/s
- Frequency: 500–1000 Hz
- Focus: confirm correct focus before the final run (focus errors show up as haze and fuzzy edges)
- Air assist / exhaust: keep airflow consistent to reduce residue and edge re-deposit
Quick dial-in method (5 minutes that saves the most material)
- Create a 4×4 (or 5×5) test grid and vary power across rows and speed across columns.
- Pick the square with the cleanest “frosted” look (good contrast, minimal melting, sharp edges).
- Save it as a preset for that acrylic type and thickness.
Tips by acrylic type (clear, glossy, thin)
Transparent / clear acrylic
Clear acrylic can show burn marks and haze more easily. Start with lower power and higher speed, and prioritize consistent airflow.
- Power: ~25%–35%
- Speed: ~300 mm/s
- Pro tip: make sure the sheet is secured so vibration doesn’t create “ghosting.”
Glossy acrylic
Glossy surfaces can be less forgiving if you overdrive power. Clean the sheet thoroughly and avoid excessive power that can produce uneven results.
- Power: ~40%–45%
- Speed: ~200–250 mm/s
Thin acrylic (e.g., 1/16")
Thin sheets are easier to warp or melt. Use lower power and increase speed to reduce heat buildup.
- Power: ~20%–30%
- Speed: increase vs. your standard preset until edges stay clean
Popular acrylic engraving applications
- Custom signage: logos, business names, event signage, desk plates
- Personalized gifts: awards, keychains, photo frames, ornaments
- Promotional products: branded coasters, plaques, tags, product display pieces
- Decor: layered acrylic art, light-up acrylic panels, templates and stencils
Workflow advantage: batch production done the “easy way”
If you’re producing acrylic items in volume, speed comes from repeatability—consistent placement, saved presets, and a layout that lets you run more pieces per job. Mega S positioning emphasizes batch-friendly workflow tools designed to reduce setup time between runs.

FAQs
What are the best settings for acrylic engraving?
A solid starter range is 30%–40% power, 200–300 mm/s speed, and 500–1000 Hz frequency—then fine-tune with a small test grid for your specific acrylic.
Can a CO2 laser cut acrylic as well as engrave it?
Yes. Cutting settings depend heavily on thickness and optics/airflow, so always test on scrap first and dial in gradually.
How do I reduce haze or burn marks on clear acrylic?
Start with lower power and higher speed, keep airflow/exhaust consistent, and make sure the sheet is secured to avoid vibration artifacts.
