Everything You Need to Know about Titanium 3D Printing

Copper, sand, alumide… we have already discussed many materials used in additive manufacturing. Today, we are focusing on titanium. It is a transition metal that is never found in its pure form in nature. To extract it, minerals such as rutile (TiO2) and ilmenite (FeTiO3) go through complex processing.

This process produces pure titanium, but it remains energy-intensive. The metal produced generally achieves a purity of 99.9%, often alloyed with other metals to create higher-performance alloys. Thanks to its characteristics, the material has become a material of choice for additive manufacturing in fields like medicine, aerospace, and automotive. So, what are its advantages and characteristics? What 3D printing technologies can be used?

What Are the Characteristics of Titanium?

Titanium, symbolized by Ti and with atomic number 22, is a material valued for its practical and versatile characteristics. It is distinguished by its lightness, strength, low toxicity, and high corrosion resistance, making it suitable for many applications. Furthermore, with a strength close to that of steel but a weight reduced by about 40%, it is particularly useful for manufacturing parts that are both lightweight and durable. Titanium is also resistant to salt water, chemicals, and wear, making it an ideal material for extreme environments. In addition to its mechanical properties, it has good thermal qualities, being able to withstand high temperatures of up to 600°C. Conversely, it remains stable even at very cold temperatures.
