Using a Marking Spray with the LaserPecker LP1 & LP2 to Engrave Metals
If you own a LaserPecker LP1 or LaserPecker LP2, you may already know that blue diode lasers cannot engrave bare metal directly.
However, you can mark stainless steel and other metals by using a laser marking spray such as xTool Black Laser Marking Spray.
Here’s everything you need to know.
Why You Need a Marking Spray
Blue diode lasers (450nm) are poorly absorbed by raw metal surfaces. Instead of engraving, the laser simply reflects off the surface.
A laser marking spray solves this problem by:
- Coating the metal with a special compound
- Bonding permanently to the surface when heated by the laser
- Creating a durable black mark
The result is a high-contrast, permanent marking — without physically engraving into the metal. We recommend xTool Black Laser Marking Spray, which yields excellent results.
- Important Usage Instructions: 1. This spray contains powder and should be shaken well before use, but avoid shaking too vigorously, as this may cause a bulge at the bottom. Shake until you hear the glass bead moving, it’s ready for use. 2. When using, do not shake vertically. Just shake it from side to side. We recommend watching the instructional video before use. 3. Do not expose it to the sun.
What Metals Can Be Marked?
Using marking spray with LP1 or LP2 works best on:
- Stainless steel
- Carbon steel
- Brass
- Aluminum (limited results depending on alloy)
It does not create depth — only a bonded surface mark.

1. Clean the Metal Surface
Remove oil, dust, or fingerprints using alcohol or a degreaser.
2. Apply the Spray
This spray contains a powder formula and must be shaken thoroughly before use. Avoid shaking it too aggressively, as this may cause pressure buildup at the bottom of the can. Shake gently until you hear the internal mixing bead moving — then it’s ready to apply.
When shaking, keep the can in a horizontal position and move it side to side. Do not shake it vertically.
Apply a thin, even coat of xTool Black Laser Marking Spray.
Let it dry completely (usually 3–5 minutes).
3. Engrave with LP1 or LP2
Load your design and use higher power with moderate speed settings.
Test on scrap material first for best results.
4. Rinse or Wipe Clean
After engraving, wash off the excess spray with water.
Only the laser-bonded areas will remain black.
What Results Can You Expect?
- Permanent black marking
- Clean, professional look
- No need for expensive fiber laser
- Ideal for logos, text, serial numbers
But keep in mind:
- No deep engraving
- Not suitable for 3D embossing
- Marking durability depends on proper application
Is Marking Spray Durable?
Yes — when applied correctly, the bonded mark is:
- Scratch-resistant
- Heat-resistant
- Long-lasting
However, it is still a surface bond, not a deep engraving.
When Should You Upgrade Instead?
If you plan to:
- Deep engrave metal
- Create textured finishes
- Engrave jewelry regularly
You may want to consider an infrared or fiber laser model instead of relying on marking spray.
Can LaserPecker Cut Metal?
Most portable LaserPecker machines are not designed for thick metal cutting.
However, the fiber-equipped LP5 can:
- Perform deep engraving
- Cut very thin sheet metal (up to ~1 mm in some cases)
For heavy metal cutting, industrial fiber cutters are required.
Is LaserPecker Good for Jewelry Engraving?
Yes — especially infrared and fiber models.
Jewelry designers commonly use:
- LP3 and LP4 for fine detail on rings and pendants
- LP5 for deeper engraving and textured finishes
The 1064nm wavelength ensures clean, high-contrast engraving without damaging delicate precious metals.
