This document contains general laser parameters for a variety of marking styles on different materials. The Fiber Laser Marking method has several programmable parameters or settings that can affect the results you might achieve on a particular material or substrate.
There are 5 main parameters that affect the marking result:
Loop Count
Speed (mm/s) (the speed at which the beam over the surface during lasering)
Performance% (percentage of total available power)
Frequency (KHz) (number of laser pulses delivered per second)
In general, lower frequencies generate less heat but are more aggressive, while higher frequencies generate more heat but are less aggressive
Hatch or fill (how objects are fixed, as opposed to just one outline)
Users can control the density, angle, and type of fill pattern. The filling is important to achieve the right type of marking
NOTE: The settings shown on the next pages are provided as a general policy and serve primarily as a starting point. Individual materials and preferences determine the final combination of settings for each application Some user experiments and tests are required. Contact FM laserto help fine-tune your laser settings to mark difficult or unusual materials and substrates.
Burning I General marking
Materials: steel, stainless steel, aluminum, brass, titanium.
Created by aggressive burning of the material. Depending on the substrate, the color of the marking varies from medium brown to black or black/grey. The surface of the material feels rough.
Glow I Black Surface Marking
Materials: steel, stainless steel, titanium.
Created by applying a large amount of heat to the surface of the material while minimizing the aggressiveness of the brand. The result is a solid black mark with a smooth surface. This type of marking is commonly used in medical applications.
Ablating I Material Removal
Materials: Anodized, black oxides, lacquered or coated materials.
Created by removing the surface-coated layer of a material, e.B. by burning the anodized layer of aluminum.
This usually results in a light or white marking in contrast to the coating. The marking is relatively smooth with minimal surface penetration.
Matting (White Surface Marking)
Materials: carbide, aluminium, stainless steel, chrome-plated, nickel-plated, galvanized.
Created by icing the surface of the material at high speed. This usually results in a light or white mark. The brands may have a light texture on touch, but the surface or coating penetration is minimal or not at all.
Depth engraving I Material removal
Materials: steel, stainless steel, aluminum, rubber, various other substrates.
Created by removing material to create a selection with depth. The resulting brand has an embossed appearance. Brand depth can vary from minimal to extreme depending on time, frequency, and performance used for the process. Removing multiple flat layers to get the desired depth is preferred.
Foam I Color Change (Plastics)
Materials: Various plastics.
Created by controlled combustion on the surface of plastic. This usually results in a white, brown or dark marking, depending on the plastic.
The marking is relatively smooth with minimized surface penetration. Controlling the heat is very important to avoid deformation of the plastic.
