Laser Marking Data: Based on [MAGIC-L2]

Writer's picture: Redt Inc.Redt Inc.

The current default settings have a large discrepancy compared to the values used on-site,

leading to repeated situations where new data needs to be provided. In the case of the MAGIC fiber laser marking machine, since the primary customers aredomestic and international jewelry-related businesses, It is necessary to modify the default settings to fit jewelry applications.

Pure metals, like gold, react weakly to lasers, so a strong single pass roughens the surface, removing the gloss before performing white marking.

For metals with low reactivity to lasers, white marking may not be visible. Therefore, mark them with a stronger first pass, followed by a lighter marking.

Offset the focus by +2.5mm to engrave. After confirming the position, adjust the height data only for engraving. It’s speculated that pulse values are corrected via arbitrary focus adjustment. It takes approximately 1 minute and 30 seconds to engrave an image on a 2.5cm pendant, resulting in a good black mark that appears to coat only the surface.

Brass tends to char easily, so simply increasing the power causes black soot to appear.

Note: Default hatching gap is 0.02mm Tapering occurs on thicker materials due to radial beam focus. Thicker beams are advantageous to reduce swelling or warping. Since cutting isn't done quickly, thermal deformation is more likely. Laser reactivity varies by metal or alloy.

For plastics, swelling and melting may occur. If power is too high, swelling worsens, and at higher frequencies, melting occurs. Faster speed is better, but the Magic Engrave machine maxes out at a speed of 1000.

Plastics that are highly reactive to energy require a wider hatching gap. Plastics are broadly divided into thermosetting and thermoplastic. Thermosetting plastics harden or burn under heat, allowing black soot or surface white marking, depending on the synthetic material. Thermoplastic, which melts under heat, boils, or liquefies. Thin letters engrave relatively well since the area exposed to heat is smaller, but wide areas can warp due to the heat.

Note: Default hatching gap is 0.02 mm

A marking method that causes surface soot, with the risk of melting on coated surfaces. Therefore, synthetic leather and rexine are difficult to engrave, but some synthetic and natural leathers are engravable. If the engraving is too strong or doesn't show up, or if a gradation effect is needed, apply the photo-marking toolpath.

A marking method that produces soot on the surface may melt coated surfaces. Therefore, engraving on synthetic leather or rexine is challenging, and only certain synthetic or natural leathers are suitable for engraving.

Note:

Spot marking with default settings, a range of 8–12 is appropriate, while 20 is too strong. To enhance marking quality, create a photo marking toolpath by enlarging the target engraving area by 1.1–1.5 times before generating the toolpath. By reducing the generated toolpath, a more concentrated engraving in the same area is possible, allowing for more precise details. However, if the density is too high, it may result in poorer gradation expression due to the points being too closely packed.
