Metallic additive manufacturing is a process that uses metal powders and advanced laser technologies to fabricate three-dimensional objects, offering precise control over the geometry of the final product.
Traditional manufacturing techniques often have limitations in producing intricate and customized metallic components, leading to higher costs and longer development times.
The process involves layer-by-layer deposition of metal powder which is selectively melted or sintered using high-powered lasers. This allows for complex geometries that are difficult to achieve with traditional manufacturing methods.
The process requires precise control over temperature, laser power, and powder layer thickness. It involves multiple steps including design preparation, material selection, printing, and post-processing (such as sintering or heat treatment).
First, a digital model is created using CAD software. Then, the metal powders are spread in layers on a build platform. A laser selectively melts or sinters the powder to form each layer of the part. This process repeats until the entire object is built.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and laser operation.
