Why Choose Slate for Laser Engraving?

Slate is a fine-grained, foliated metamorphic rock that offers a rustic yet elegant look when engraved. Its durability, natural color variation, and matte finish make it a perfect candidate for high-contrast engraving. However, slate engraving with CO2 laser requires proper setup, safety considerations, and a machine that can handle it all with precision.

How to Laser Engrave on Slate: Step-by-Step Guide

1. Choose the Right Slate
Start with untreated, natural slate tiles. Avoid lacquered or pre-treated versions unless you're experienced in adjusting power settings or using masking materials.

2. Clean the Surface
Wipe down your slate with a lint-free cloth and rubbing alcohol to remove dust or oils. A clean surface ensures a crisper result during slate engraving with CO2 laser.

3. Prepare Your Design File
Use vector software like Adobe Illustrator or CorelDRAW to prepare your file. High-contrast black-and-white images or text work best.

4. Machine Setup: Enter Monport Mega 70W
Now comes the exciting part—engraving with the Monport Mega, a high-speed 70W CO2 desktop engraver with autofocus and integrated air assist.

Recommended Monport Settings for Slate Engraving:

• Power: 80–100%

• Speed: 200–400 mm/s

• Interval (DPI): 0.1–0.15mm (254–300 DPI)

• Passes: 1 (usually sufficient)

Always start with a test run on a scrap piece. The precise speed and power will depend on the slate's density and color.

5. Use Air Assist and Autofocus
The Monport Mega’s auto-focus feature adjusts to slate’s irregular surface, while air assist keeps your engraving area clean and reduces soot, producing sharp, consistent lines.

6. Watch for Smoke and Dust
The Monport Mega’s exceptional air duct system provides powerful smoke exhaust, maintaining a clear engraving path and protecting your optics.

Slate Engraving with CO2 Laser: Creative Ideas to Try

If you’ve mastered the basics of how to laser engrave on slate, here are some creative project ideas:

• Personalized coasters

• Pet nameplates

• Rustic kitchen signs

• Wedding gifts or event signage

Each of these applications thrives with the clarity and depth that slate engraving with CO2 laser provides, especially when done with the Monport Mega.

Tips for Better Engraving Results

• Use Light Mist Spray: A light spritz of water before engraving can minimize debris and darken the contrast even more.

• Avoid Deep Cuts: Unlike wood or acrylic, slate doesn’t benefit from multiple passes—it may chip or fracture. Aim for surface etching.

• Use Masking Tape for Alignment: While Monport Mega has visual light alignment, masking tape can be helpful for positioning designs on odd-sized slates.
