This is my second video with the xTool S1. I the first video, I demonstrated how to laser cut wood scales. You can watch that video HERE.
I this tutorial, I'll show you how to used the xTool S1 1064nm Infrared laser module to engrave the stainless steal blades of these knives.
The 20W blue laser module that is the default emits light at a wavelength of 455 nm, while the 2W infrared module emits light at 1064 nm, the same wavelength used in many fiber lasers that are normally used for engraving metals. This difference in wavelength is significant because various materials absorb light differently at different wavelengths. As a result, the infrared laser can engrave materials that the blue laser cannot.
The 1064 nm infrared laser module is capable of engraving the following materials: all metals ( including gold, silver, platinum, aluminum, copper, zinc, titanium, iron, stainless steel, metal oxides, and alloys), leather, opaque plastics, some acrylics, stones/ceramics, and circuit boards.
Despite its relatively low power of 2W, this infrared laser module is not primarily intended for cutting or deep engraving, and therefore the lower power works well for surface engraving.
The spot size of the infrared laser is approximately 0.05 x 0.05 mm, which is smaller than the 20W laser with a spot size of 0.08 x 0.10 mm. This smaller spot size means the infrared laser beam achieves higher power density and can engrave finer details.
