About Project

Here are three 3D-printed stainless steel 316L chain circles with different surface effects – the raw finish, electroplated silver, and PVD-plated black. Binder Jet 3D printed parts could be strengthened with some post-processing techniques, including curing, sintering, infiltration, polishing and plating. The metal materials could be much stronger and more durable than their green stage.

Solution

  • Step 1: After confirming the requirements with the client, the chain circles are suggested to be printed with binder jetting technology and stainless steel powder.
  • Step 2: In metal binder jetting, a liquid binder is selectively applied to join powder particles, layer by layer. The process begins by spreading a thin layer of powder, with printheads strategically depositing droplets of binder into the powder bed. The printing plate then lowers and another layer of powder is spread.
  • Step 3: When printing is completed, remove the extra material for recycling. Clean the surface of the model with compressed air. There are no supports that need to be removed.
  • Step 4: Smoothen the surface with electrolytic polishing technique and coat them into silver and black with electroplating and PVD (Physical Vapor Deposition).
