Electroplating lets you incorporate the strength, electrical conductivity, abrasion and also corrosion resistance, and appearance of certain metals with various materials that boast their own benefits, such together affordable and/or lightweight steels or plastics.

You are watching: What mass of copper would be electroplated on the cathode

In this guide, you’ll discover why plenty of engineers usage electroplating in every phase of manufacturing—from prototyping come mass production.


Electroplating is the process of using electrodeposition to coat an object in a class of metal(s). Engineers use regulated electrolysis to deliver the desired metal coating from an anode (a part containing the metal that will be used as the plating) to a cathode (the component to be plated).

The anode and also cathode are put in an electrolyte chemical bath and also exposed come a consistent electrical charge. Electricity causes negatively charged ions (anions) to relocate to the anode and positively charged ion (cations) to deliver to the cathode, extending or plating the desired component in an also metal coating. Electroplating take away a substrate product (often a lighter and/or lower-cost material) and encapsulates the substrate in a thin covering of metal, such as nickel or copper.

Read on to learn how designers are adding metal come resin 3D prints, and also why hybrid metal parts deserve to open doors come a surprising selection of applications, including (but not minimal to) end-use strength and also durability.


Electroplating and also electroforming room both performed using electrodeposition. The difference is the electroforming offers a mold that is gotten rid of after a part is formed. Electroforming is provided to create solid metal pieces, vice versa, electroplating is supplied to cover an existing part (which is make of a different material) in metal.


You deserve to electroplate a single metal ~ above an object, or a combination of metals. Countless manufacturers select to class metals, such as copper and nickel, to maximize strength and conductivity. Materials generally used in electroplating include:

Brass

Cadmium

Chromium

Copper

Gold

Iron

Nickel

Silver

Titanium

Zinc

Substrates deserve to be do of nearly any material, indigenous stainless steel and also other steels to plastics. Artisans have electroplated organic materials, such together flowers, and soft cloth ribbons. 

It’s crucial to keep in mind that non-conductive substrates such as plastic, wood, or glass must first be made conductive prior to they can be electroplated. This deserve to be done by coating a non-conductive substrate in a class of conductive repaint or spray.


Thanks to scientific developments in materials and also plastic manufacturing, lightweight and also low expense plastic parts have replaced an ext expensive steel parts in a wide variety of applications serving miscellaneous industries, native automobiles to pipes pipes.

Although plastic boasts an array of advantages over metal, there are countless applications where metal still reigns supreme. Try as friend might, you’ll never get plastic to have actually the very same opulent end up as copper. And also while plastic might be much more flexible 보다 the bulk of metals, the not virtually as strong. This is whereby electroplating come in.

3D printing supplies unique benefits when combined with electroplating. Engineers often select to 3D print substrates because of additive manufacturing’s style freedom. That is often cheaper to electroplate 3D printed components than to cast, machine, or usage other production methods, especially when it pertains to prototyping.

Stereolithography (SLA) 3D printing is appropriate for electroplating due to the fact that it creates 3D printed components with very smooth or carefully textured surfaces that make the transition between the two materials—plastics and also metals—seamless. It additionally creates watertight parts that won’t get damaged when submerged in the chemical bath required during the electroplating process.

From an design standpoint, the combination of 3D printing and also electroplating offers unique tensile strength choices for finished designs. As you deserve to see in the graph above, the combination of this two manufacturing processes bridges the gap in tensile strength in between the two material groups.


In this webinar, learn how electroplating increases the product palette of SLA 3D to press to achieve high-stiffness, undertake resistant end-use parts.


Electroplating offers numerous benefits, consisting of increased strength, lifespan, and also conductivity that parts. Engineers, manufacturers, and artists capitalize top top these benefits in a range of ways.

Engineers regularly use electroplating to rise the strength and durability of assorted designs. You deserve to increase the tensile strength of 3D printed parts, because that example, through 400% or much more by coating lock in steels such as copper and nickel. Place a metallic skin top top polymer parts and you deserve to improve their resistance come environmental components like chemistry exposure and UV light.
