What Metals Can You 3D Print?

As the field of 3D printing continues to advance, the range of materials that can be printed expands as well. While many people associate 3D printing with plastic, the technology has evolved to allow for printing with a variety of metals as well. In this article, we will delve into the topic of what metals can be 3D printed and how the process works.

Titanium

One of the most popular metals used in 3D printing is titanium. This material is ideal for medical implants, aerospace parts, and high-performance sports equipment. The reason for its popularity is that it is lightweight, strong, and biocompatible. Titanium powder is used in 3D printing with a process called Direct Metal Laser Sintering (DMLS).

Stainless Steel

Stainless steel is another popular metal used in 3D printing. It is widely used in the aerospace and automotive industries for its strength, durability, and resistance to corrosion. It is also used in the manufacturing of jewelry and consumer goods. Stainless steel is 3D printed using the Selective Laser Melting (SLM) process.

Aluminum

Aluminum is a lightweight and low-density metal that is widely used in the aerospace and automotive industries. It is also used in the manufacturing of consumer goods such as smartphones and laptops. Aluminum is 3D printed using the same process as stainless steel, SLM.

Cobalt Chrome

Cobalt chrome is a popular metal used in the medical industry for dental implants and orthopedic implants. It is also used in aerospace and automotive industries. The metal is biocompatible and has excellent mechanical properties. Cobalt chrome is 3D printed using the Electron Beam Melting (EBM) process.

Copper

Copper is a highly conductive and malleable metal used in the electronics and electrical industries. It is also used in the manufacturing of jewelry and sculptures. Copper is 3D printed using the Direct Metal Laser Sintering (DMLS) process.

Gold

Gold is a highly valued and sought-after metal used in the jewelry and decorative arts industries. It is 3D printed using the Direct Metal Laser Sintering (DMLS) process. However, due to its high cost, gold 3D printing is not widely used.

Inconel

Inconel is a family of nickel-based superalloys that are highly resistant to corrosion and high temperatures. They are used in the aerospace and automotive industries for their strength and durability. Inconel is 3D printed using the Direct Metal Laser Sintering (DMLS) process.

The range of metals that can be 3D printed continues to expand as the technology advances. The metals that can be printed include titanium, stainless steel, aluminum, cobalt chrome, copper, gold, and Inconel. Each metal has unique properties that make it ideal for specific applications. The process used to 3D print each metal varies, but the most commonly used processes are SLM, DMLS, and EBM. As 3D printing technology advances, we can expect to see more metals added to the list of materials that can be 3D printed.
