3D Printing with Titanium
Titanium is a metal with a number of advantages. Both lightweight and mechanically strong, it is also biocompatible and resists corrosion very well. Because of these properties it is a widely used material in high-tech fields such as aeronautics, space exploration and the medical field.

3D Printing with Titanium: Advantages and Disadvantages
Titanium 3D printing has many advantages when compared to traditional manufacturing methods. Here is a quick overview:
Complexity of parts: Titanium 3D printing can produce complex
shapes that would not otherwise be feasible. This creates
many possibilities in terms of design and parts optimisation.
Mechanical properties: Parts printed in titanium retain very
good mechanical properties and can be produced in a batch.
This eliminates welding steps, which can create impurities
and areas of weakness in the metal.
Reduced production time and increased flexibility: 3D printing
eliminates several steps in the manufacturing processes
and allows parts to be produced in a few hours or days,
Reduced titanium waste: Titanium is an expensive metal and
traditional manufacturing methods function by removing
material. This generates a lot of wasted material (shavings,
etc.) and thus a high cost. Titanium 3D printing therefore
However, the cost of titanium 3D printing remains high. The industry still has a few challenges to overcome to improve this technology, such as reducing the cost of titanium powder.
