The xTool P2 is a 55W CO2 laser engraving machine capable of marking stainless steel, titanium, brass, anodized aluminum, and other metal surfaces. This guide will walk you through the process of using metal marking spray for metal engraving.

Please note: If the lens isn't regularly cleaned or the optical path requires adjustment, the processing power might fall below 40W, which could impede the machine's ability to mark metal materials.

Steps for Using Metal Marking Spray

Step 1: Clean the metal surface to remove any residual grease. 

Apply a thin, even coat of metal marking spray to the area slated for marking. To achieve a high-quality marking effect, the uniformity of the product coating is essential, which may require several tests and practice. Always use the product in a well-ventilated area or a designated spray room.

Please note: xTool doesn't provide or sell 'Metal Mark Spray'. You can purchase it from Amazon or Etsy.

Step 2: Get a stainless steel dog tag.

Step 3: Evenly spray the marking liquid on the surface using an airbrush or sprayer.

Remember to place a piece of waste cardboard beneath the metal. Also, use the marking spray in a well-ventilated area or a designated spray room for proper air circulation.

Step 4: Allow the surface to air dry for 3-5 minutes.

For optimal results, let the liquid dry naturally. It's not recommended to force it to dry using heat lamps, blowers, or fans.

Step 5: For substrates that shrink significantly, apply a second coat.

However, ensure the first coat dries for at least 30-40 seconds before applying the second one.

Step 6: Set parameters and initiate engraving.

Different metal marking sprays can produce varying sintering and engraving effects. It's recommended to conduct multiple test marks to achieve the best performance.

Step 7: Remove excess spray paint.

Wash with water or a damp towel or sponge. Typically, rinsing with running water for 3-5 seconds is sufficient to remove excess spray. If the engraved portion remains, a damp sponge and alcohol can be used for localized cleaning.

Please remember that different brands of marking sprays may require a bit of experimentation to optimize with specific substrates. All lasers react differently depending on the substrate. More information about power and speed settings will be updated in the official xTool material database.

Cleaning instructions: Rinse with water or use a damp towel or sponge.
