Finishes Stainless steel 3D printing results in parts with a density equal to that of machined steel. They can also be machined or polished in the same fashion. Standard: Standard finishing refers to the removal of any support structures. The surface of the part is also medium blasted to create a uniform appearance. CNC Machining or Polishing: In some cases, specific features can be machined or polished using a CNC unit. However, these are evaluated on a case-to-case basis. Cost-saving Design Tips To save money when stainless steel 3D printing, consider the following cost-saving tips: DFM: Design-for-manufacturing (DFM) principles are important. When designing parts for metal 3D printing, make sure that any enclosed areas have holes from which to remove unfused powder after printing. Material Choice: DMLS stainless steel 3D printing can produce high-strength functional parts, but it is not cheap. Ensure that stainless steel is necessary for your application over cheaper 3D printing metals like stainless steel or composite metals printed with binder jetting.
