If you’re using metal 3D printing in China to create prototypes or end-use parts, you may want to know about electroplating. This metal finishing process coats the printed part with a thin layer of metal using electricity to improve durability and aesthetics. Plus, it adds to the strength of the component.
Most 3D printers in China offer various options such as nickel, zinc, and copper to optimize your part. This guide will help you navigate electroplating, its advantages, and the best practices.
Why electroplating?
Electroplating improves the durability and strength of parts printed using direct metal laser sintering (DMLS), making it an essential step in post-processing. Adding a protective layer to the metal parts can make them more resistant to abrasion, wear, and corrosion. Beyond that, here are more reasons to consider it for metal 3D printing in China:
• Add a matte or shiny finish to the part, enhancing its texture, color, and overall aesthetics.
• Add a layer that reduces or boosts the resistance or capacitance to alter the part’s electrical conductivity.
• Replace costly materials with affordable ones or use fewer materials to minimize the part’s cost and weight.
Techniques for electroplating DMLS parts
Electroplating can be performed directly on some metals produced using powder bed fusion techniques, such as DMLS. As a post-treatment, it enhances the conductivity and surface quality of these metals. Titanium, for example, may need etching or polishing before plating with chrome or nickel.
Considerations to Optimize Metal Parts
Electroplating can impact the post-processing and design of 3D-printed metal parts, but there are best practices to improve outcomes:
• Design electroplating: Avoid features that can trap air bubbles or cause uneven plating, such as corners, sharp edges, cavities, or holes. Adding hooks, tabs, and other similar features can help with electrical contact and handling.
• Prepare the part: Make sure it doesn’t have oil, oxide, or dirt that can reduce the plating quality. Additionally, pick the right metal ions and electrolytic solution that suits the purpose and material of the part.
• Control the parameters: Check the agitation, voltage, and pH of the electrolytic solution to avoid defects.
• Finishing: Rinse and dry the 3D-printed metal part to remove any excess metal ions or solution that can lead to contamination or corrosion. This is also the time to apply any final layer or post-treatment to enhance the metal coating’s surface quality and longevity.
