![]() This is used to improve the mechanical and tactile properties of the surface.Įlectropolishing. Here are the other ways to improve the surface quality of your 3D printed metal during the additive manufacturing process. For instance, internal surfaces such as those in internal or tempering channels can be polished using abrasive flow machining. ![]() Thus, you have to add metal-machining finishes to meet the requirements of surface quality and geometry.įollowing the removal of support structures to separate the parts from the building platform, you can mill, drill or polish. To achieve the necessary specifications or improve the properties of surface quality, geometrical accuracy and mechanical properties, a post-process is necessary. The process is repeated until the whole part is complete. When the scanning process is complete, the build platform moves downwards by one layer thickness and the recoater spreads another thin layer of metal powder. The entire area of the model is scanned so the part is built fully solid. It is then heated to the optimal build temperature.Ī thin layer of metal powder is spread over the build plate platform and a high power laser scans the cross-section of the component, melting (for fusing) the metal particles together and creating the next layer. The build plate chamber is filled with inert gas to minimize the oxidation of the metal powder. Metal Additive Manufacturing works in the following process. But this offers a lot of benefits from the traditional metal manufacturing processes. Unfortunately, metal 3D printers are very expensive. ![]() The aviation industry saves billions of dollars through this weight reduction due to fuel. 3D printed metals are 60% lighter than their machined counterparts. With metal additive manufacturing printing process, this can be done with lesser energy and waste. For instance, when aircraft manufacture metal parts, the majority of the material up to 90% is cut away. Traditionally, metal and plastic objects can be a wasteful process. This technology offers unrivaled design freedom with the ability to manufacture parts from a wide range of materials.Ī number of components that were impossible to create a few years ago can be made to high standards using 3D printing metal powder.Īdditive manufacturing or 3D printing allows you to create a three-dimensional part layer by layer from a polymer or metal-based material. Metal Additive Manufacturing is a printing process also known as metal 3D printing. In some cases, they are collectively referred to as metal 3D printing. Meanwhile, in DMLS or direct metal laser sintering, the powder is composed of materials with variable melting points that fuse on a molecular level at elevated temperatures.īoth SML and DMLS are used in industrial applications to create end-user engineering products. SLM printing process uses metal powders with a single melting temperature and fully melts the particle while The only difference between the two comes down to the fundamentals of the particle bonding process. Both processes use metals in granular form. This additive manufacturing printing process covers the basic principles of SLM (Selective Laser Melting) and DMLS (Direct Metal Laser Sintering).
