SLM and DMLS are advanced 3D printing technologies that can produce parts in a variety of metals and metal alloys, including aluminum, stainless steel, titanium, cobalt chrome and Inconel. These materials are ideal for a wide variety of industrial applications from aerospace to medical. While precious metals such as gold, platinum, palladium and silver can also be processed, their primary applications are largely limited to jewelry making. However, it’s worth noting that metal 3D printing powders are costly. For example, stainless steel 316L powder costs around $350 - $450 per kg. Therefore, the need to minimize part volume and support structures is critical to keeping costs as low as possible. One of the key advantages of metal 3D printing is its compatibility with high-strength materials such as nickel or cobalt-chromium superalloys. Processing these materials using traditional manufacturing methods is very challenging. Significant cost and time savings can be achieved by utilizing metal 3D printing to create near-net-shape parts that can be post-processed to achieve a high surface finish. In conclusion, metal 3D printing offers a wide range of materials suitable for various applications and is able to handle challenging high-strength materials. However, the expensive nature of metal 3D printing powders must be considered and the design optimized accordingly.Advantages These parts can also be optimized for maximum performance, minimum weight and reduced assembly complexity.

Furthermore, the build size of metal 3D printing systems is limited due to the need for precise fabrication conditions and process control. Previously designed parts may need to be modified to ensure compatibility with metal 3D printing technologies.First, the DMLS machine uses a laser to sinter each layer on a bed of metal powder, starting with the support structure and then the part itself. After each layer of · micro-welding, the build platform moves down and the recoating blade deposits the next layer of powder. This process continues until the build is complete. Loose powder is manually removed and parts are subjected to a heat treatment cycle to relieve stress. Then, the support structure is removed, and the part is sandblasted and deburred. The final DMLS part is almost 100% dense.Advantages of metal 3D printing include the ability to create complex custom parts not possible with traditional manufacturing methods.
