Scotle Fiber Laser Marking Machine FAQs

A high-power marking machine can cut thin metal using multiple passes, but it is primarily designed for marking and engraving rather than efficient cutting. For practical use, stainless steel of 1 mm or less and brass of approximately 1.5 mm or less are recommended.

Under suitable conditions, up to approximately 2 mm stainless steel may be processed, but cutting is slow and requires repeated downward focus adjustment on a 2D machine. A 2.5D machine is better for thicker cutting because its motorized Z-axis can follow the cutting depth automatically.

Stainless steel may darken around the cutting edge because of heat input. For regular metal cutting, a dedicated fiber laser cutting machine is recommended.

A 2D machine can perform deep engraving, but it cannot automatically create true 3D relief. As the engraving becomes deeper, the operator must manually lower the focus to keep the laser focused on the processing surface. This makes the process slower and less efficient.

A 2.5D fiber laser marking machine has a motorized Z-axis. After the initial focus is set manually, the software controls the Z-axis during processing so the focal point follows the engraving depth automatically. This improves efficiency, depth consistency, and engraving quality.

Yes. Depending on the control system and software, 2.5D and 3D fiber laser marking machines can process deep engraving, layered relief, curved surfaces, cylindrical surfaces, and selected 3D shapes. A suitable 3D model or grayscale bitmap is required.

There is no single fixed maximum depth. It depends on the material, laser power, engraving area, Z-axis travel, lens, parameters, and acceptable processing time.

As a test reference, a 100W fiber laser marking machine engraved a 25 mm diameter pattern with a relief depth variation of approximately 0.5–1.5 mm on aluminum alloy at 70% power. The processing time was 57 minutes and 58 seconds.

Maximum pulse energy indicates the energy delivered in a single laser pulse. Higher pulse energy generally provides stronger material removal and is helpful for deep engraving. It may also increase the heat-affected area, so parameters must be adjusted according to the material.
