3D Plus™ Electroplating

Electroplating 3D Printed Parts

Electroplating is the process of depositing a thin layer of metal on the surface of the 3D printed parts using an electric current, which enhances the durability, conductivity, and aesthetics of printed parts. Electroplating works with SLA resin parts and SLM metal parts at 3DSPRO.

What is electroplating?

Electroplating is a process that uses an electric current to deposit a thin layer of metal onto the surface of another material, usually for protective, decorative or functional purposes.

The object to be plated is immersed in an electrolyte solution containing metal ions, and then an electric current is applied, which causes the metal ions to adhere to the surface of the object, forming a uniform and durable coating.

Electroplating is used in a wide range of industries, from jewelry manufacturing to electronics, to enhance the performance and appearance of components.

The Advantages of Electroplating

1. Electroplating adds a layer of metal that protects the underlying material from wear and corrosion.

2. Provides a smooth, shiny, and appealing finish, often used to give a high-end look.

3. Adding a metal layer improves the electrical conductivity of non-metallic parts, useful in electronics.

4. Allows for the use of less expensive materials by coating them with a thin layer of a more expensive metal.

5. Can be applied to a wide range of materials and shapes, making it suitable for various applications in different industries.

Electroplating Process

1. Surface Preparation: Clean and sometimes polish the object to remove any dirt, oil, or oxidation, ensuring a smooth surface for the metal to adhere to.

2. Etching: If needed, etch the surface with a mild acid to create tiny grooves that help the metal bond better.

3. Electrolyte Bath: Submerge the object in an electrolyte solution containing metal ions of the plating material.

4. Applying the Electric Current: Connect the object (cathode) and a piece of the plating metal (anode) to a power source. The current causes metal ions to move from the anode to the cathode, coating the object with a thin layer of the metal.

5. Rinsing and Drying: After plating, rinse the object to remove any residual solution and then dry it thoroughly.

Quality Inspection Process

Check out the quality inspection process of electroplated parts at 3DSPRO.

Visual Inspection
Check for surface defects such as blisters, pits, roughness, or uneven coating.

Thickness Measurement
Use tools like micrometers or X-ray fluorescence (XRF) to measure the thickness of the electroplated layer and ensure it meets the required standards.

Adhesion Test
Perform tests such as a bend test, tape test, or thermal shock test to ensure that the coating adheres properly to the substrate.

Hardness Test
Measure the hardness of the coated surface to ensure it matches the specifications.

Corrosion Resistance Test
Conduct tests like salt spray or humidity testing to assess the coating’s resistance to corrosion.

Coating Uniformity
Ensure that the coating is uniformly distributed across all surfaces, including hard-to-reach areas.

FAQs

Check out the frequently asked questions of electroplating.

Can I electroplate all types of 3D printed parts?-

Generally, parts made from conductive materials or those that can be coated with a conductive layer can be electroplated. Common materials include metals and certain plastics like ABS and resin when treated with a conductive spray.
What are the benefits of electroplating 3D printed parts?+

Electroplating enhances durability, conductivity, and aesthetics. It provides a metallic finish, improves wear resistance, and can protect the parts from corrosion.
How thick is the electroplated layer on 3D printed parts?+

The thickness typically ranges from a few microns to several tens of microns, depending on the application's requirements and the duration of the electroplating process.
Is the electroplating process environmentally friendly?+

Electroplating can involve hazardous chemicals, but many modern processes have been developed to be more eco-friendly. Proper waste management and the use of less toxic chemicals can mitigate environmental impact.
Can electroplated parts be used in functional applications?+

Yes, electroplated parts are often used in functional applications due to their improved mechanical properties, electrical conductivity, and resistance to wear and corrosion.
