How to Process 3D Laser Engraving?

I. What is 3D laser engraving?

Laser cutting is the use of high power density laser beam to scan the surface of the material, and heat it to several thousand to ten thousand degrees Celsius in a very short period of time to melt or gasify. And then, blow away the melted or gasified material from the cutting seam with high pressure gas to achieve the purpose of cutting the material. So, how to do 3D laser engraving?

II. How to do 3D laser engraving

Relative to two-dimensional laser cutting, 3D laser engraving needs to constantly adjust the laser cutting head posture, in order to ensure that the 3D tube laser cutting head is always perpendicular to the surface of the workpiece, so as to obtain excellent cutting quality. In actual production, 3D laser engraving programming needs to build 3D modeling of parts first, then import 3D programming system generation path, and needs to be manually adjusted according to the characteristics of parts and tooling to avoid the collision of cutting head. The operation is complex  and the workload is large. As the cutting head of 3D laser engraving machine is equipped with a capacitive sensor offered by the laser cutter manufacturer, it can automatically adapt to the shapes of parts, and always keeps a certain distance from the parts for cutting. Therefore, the 2D programming system of 3D laser engraving machine can meet the production needs only when the parts surface changes not dramatically.

III. Materials can be processed by 3D laser engraving

Stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminized zinc plate, pickling plate, copper, silver, gold, titanium and other metal sheets and pipe cutting.
