Most people are aware of 3d laser cutting, but few understand the technicalities behind the highly complex process. The purpose of 3d laser cutting is to get automated precision and speed when cutting across three dimensions. The laser cutting method is applied for different kinds of materials where the contours are complex but demand precise and fast cutting. There are no distortions seen with the method that is able to achieve high-precision cuts.
The Process Of 3D Laser Cutting
3D laser cutting process involves a highly coherent light beam that is focused on the areas. As the jet of gas is thrown on the surface, the material either melt vaporizes or burns away. Fibre lasers are commonly used for 3D cutting because of their superior advantages of flexibility and precision. No matter what kind of laser or technology is used, the 3D laser cutting is always fast, accurate and precise. When it comes to speed, precision, and cost, there are very few processes that can compare with 3D laser cutting.
Different Metals Cut By 3D Lasers
3D laser cutting can be used for almost all kinds of metals such as aluminium, mild steel, stainless steel, and others. Laser cutting is cost-effective for small-batch production, and the main benefit here is that one can work on small focal diameters and with minimal heat input. 3D laser cutting can process Stainless steel with laser fusion cutting. Copper and other metals with high heat conductivity are preferred for laser cutting. Precious metals, like gold, silver, and platinum can be easily cut with 3D laser cutting and minimal heat input.
Advantages Of 3D Laser Cutting
3D laser cutting process can be used on different materials of different thicknesses. The whole laser power is focused on one point, and the lasers can work on minute areas of even less than half a millimetre. As the laser beam can cut through without any contact and thus one can expect no damage to the workpiece. There are several advantages of working with 3D laser cutting.
The Wide Range of Material – The 3D laser cutting can be used on different material and metals like aluminium, non-ferrous metals, and stainless steel as well as plastics, glass, wood, and ceramics. The extremely wide range of material expands the application of 3D laser cutting.
Handling Complex and Intricate Contours – The 3D laser cutting offers higher contour freedom as the workpiece is exposed to minimal thermal stresses. The intricate contours can be cut easily and smoothly and free of any mistakes. There is no need for spending time on post-processing as you get precise results.
High-Quality Edges and Shapes – 3D laser cutting can vaporize any material, and the process is so fast that one cannot detect the impact of any heat. Thus, there are no melted materials and what you get is fine and high-quality cutting edges. Thus, the technology is most suitable for medical technology and the display industry where those lasers cut through chemically hardened glass with the most precision.
The parameters that can influence the 3D laser cutting process include the focus position and focal diameter, the power of the laser, the nozzle diameter and the operating mode. The focal diameter controls the gap width and determines the form of the kerf. The laser power controls the precise amount of energy per surface area unit while the nozzle diameter regulates the gas quantity. Continuous wave operation or pulsing operating mode determines the continuous flow of laser energy or with interruptions.
When it comes to cutting metal and non-metal materials, the first choice is the 3D laser cutting process that can cuts any contour quickly and with precision.
