Understanding Tungsten in Additive Manufacturing

What is Tungsten?

Tungsten, symbolized by W on the periodic table, is a remarkable metal known for its exceptional hardness and high melting point. It is often referred to as “heavy metal” due to its density, which is comparable to gold. additive manufacturing tungsten finds applications in various industries, ranging from aerospace and defense to electronics and medical.

Properties of Tungsten

Tungsten boasts an array of properties that make it ideal for additive manufacturing. These properties include its high melting point, excellent thermal conductivity, low coefficient of thermal expansion, and outstanding mechanical strength.

Tungsten in Traditional Manufacturing

Before we delve into additive manufacturing with tungsten, it is essential to understand how this metal has been used in traditional manufacturing processes. Tungsten has a rich history of applications in the production of electrical wires, filaments, and various alloys, such as steel and superalloys.

Additive Manufacturing Techniques Using Tungsten

Powder Bed Fusion (PBF)

One of the most popular additive manufacturing techniques using tungsten is Powder Bed Fusion. This process involves spreading a thin layer of tungsten powder and selectively melting it using a high-energy laser or electron beam. The process is repeated layer by layer, creating a solid, dense, and intricate tungsten component.

Directed Energy Deposition (DED)

Directed Energy Deposition is another additive manufacturing method that incorporates tungsten. In this technique, a focused energy source, such as a laser or electron beam, is used to melt tungsten wire or powder, which is precisely deposited onto a substrate to build the desired object.

Binder Jetting

Binder Jetting is a unique additive manufacturing process where layers of tungsten powder are selectively bound together using a binding agent. The unbound powder is removed, and the bound layers are sintered to create the final part.

Material Extrusion

Material Extrusion, commonly known as Fused Deposition Modeling (FDM), is a technique where a continuous strand of tungsten-filled thermoplastic is extruded and deposited layer by layer to form the desired shape.
