What is Copper? Understanding Its Thermal and Electrical Conductivity

Wax Casting

Our Copper

parts are made from solid, 100% copper using a precision lost-wax investment casting process. Copper naturally features a warm red-orange tone that gradually develops a darker brown, blue, or green patina over time, depending on

environmental exposure.

Each piece begins as a high-resolution wax 3D print,

which is used to form a mold for casting. This process allows for exceptional detail and accuracy, resulting in a refined, professional appearance. As the copper oxidizes, it forms a

naturally corrosion-resistant surface layer that enhances durability and character.

Accessible exterior surfaces

are polished to achieve a smooth finish. Due to the nature of the process, narrow or enclosed internal features may remain unpolished

and retain a natural cast texture.

Frequently Asked Questions About

Copper 3D Printing Wax Casting

What is Copper 3D Printing Wax Casting?

Copper 3D Printing Wax Casting is a manufacturing process that combines high-resolution wax 3D printing with traditional lost-wax investment casting. A wax model is printed first, then used to create a mold into which molten copper is poured. This method allows for complex geometries, fine surface detail, and solid metal parts that cannot be achieved through direct metal printing alone.

What material is used for the final part?

The finished parts are made from 100% solid copper. Copper is valued for its thermal and electrical conductivity, durability, and distinctive appearance. Over time, the surface naturally oxidizes, forming a protective patina that may range from brown to blue or green depending on the environment.

What level of detail can be achieved?

Lost-wax casting is well suited for intricate and detailed designs. Fine features, smooth curves, and complex shapes can be accurately reproduced from the wax model. This makes the process ideal for functional components, artistic pieces, and decorative parts that require a high-quality finish.

How does the surface finish look?

Exterior and well-reachable surfaces are polished to create a smooth, refined appearance. However, internal cavities or tight spaces that are not accessible during post-processing may retain a natural cast texture. Minor surface variations are normal and part of the casting process.

Will the copper change color over time?

Yes, copper naturally reacts with air and moisture, forming an oxidized surface layer known as a patina. This process is normal and helps protect the metal from further corrosion. The final color depends on environmental conditions and can add character and uniqueness to each part

Are there design limitations to consider?

Designs should account for casting constraints such as minimum wall thickness, enclosed cavities, and internal channels. Extremely thin or fully sealed internal features may be difficult to cast or finish. Design guidelines are recommended to ensure the best results and structural integrity.

What applications is this process best suited for?

Copper 3D Printing Wax Casting is ideal for prototypes, functional parts, heat-transfer components, electrical elements, and decorative or artistic objects. It is especially useful when complex geometry, solid copper material, and a premium metal finish are required.

Protection

IP protection is what most people are worried about when it comes to 3D printing because we get orders in which we have to copy the original design precisely.

Non-Disclosure Agreements

We uphold strict confidentiality by default for all customer communication, projects, and models. Should you prefer a formal agreement, we offer standard NDAs or can review your own. Your trust is our priority.
