Titanium is a widely used metal in additive manufacturing, finding extensive applications in aerospace, joint replacements, surgical tools, racing and bicycle frames, electronic products, and other high-performance industries. Its popularity stems from its exceptional mechanical strength, superior strength-to-weight ratio, and superior corrosion resistance compared to stainless steel. The utilization of titanium enables lighter rockets and aircraft, leading to fuel savings and increased payload capacity. It is also employed in the production of lightweight electronic devices such as smartphones and VR goggles, as well as in the field of medical implants.
Titanium's prominence in 3D printing is evident in the production of various products, including medical devices, high-performance bicycles, luxury watches, and consumer electronics.
Wristwatch
In 2023, Panerai introduced the Submersible S Brabus PAM01283, featuring a 3D-printed titanium case. Additionally, Holthinrichs Deconstructed unveiled the first 3D-printed titanium watch. These innovations aim to provide lightweight and robust products through innovative and often customized designs.
3D printing enables the manufacturing of intricate and thin-walled titanium parts, frequently utilized in watch case production, as demonstrated by Panerai and Holthinrichs watches. It has been speculated that titanium alloy watch cases will also be incorporated into the upcoming Apple Watch Ultra.
Precision Products and Electronic Devices
The 2023 model of the Honor Magic V2 foldable smartphone showcased a 3D-printed titanium alloy hinge displacement cover. Honor, a smartphone manufacturer, utilized a 3D-printed titanium hinge displacement cover in the new foldable Magic V2. This cover is lighter than the previous aluminum version and offers a 150% increase in strength. Honor emphasized that the thousands of small titanium pieces that can be 3D printed play a crucial role in the product's durability and smooth folding and unfolding.
High-Performance Bicycles
The use of 3D-printed titanium alloy is prevalent in modern high-performance bicycles. Titanium is employed in various components such as cranks, brake levers, handlebars, derailleur hangers, and even the entire bicycle frame. It offers the strength of aluminum and the lightness of carbon fiber without the sustainability concerns associated with carbon fiber. Bicycle manufacturer Carbon Wasp explains their decision to embrace 3D-printed titanium for their latest aftermarket crank arms, abandoning aluminum and carbon fiber.
Aerospace
In the aerospace industry, titanium-based additive manufacturing components are currently utilized for commercial and military purposes. Gecan Aerospace announced plans in 2023 to establish a large-scale 3D printing unit as part of its new Global Technology Center in Texas. This center will specialize in 3D printing titanium aircraft structures. The Cell 3 printer, capable of printing titanium alloy components up to five meters in length, will enable the production of 3D-printed titanium components for the lunar deployable arm, a more efficient approach compared to traditional manufacturing methods, as required by NASA.
In conclusion, the future of 3D printing with titanium holds great promise and will continue to play a significant role in various industries. Through continuous technological innovation and expanded applications, 3D printing with titanium will bring increased convenience, efficiency, and high-quality metal components to society.
