Titanium and titanium alloy materials of metal 3D printing materials
Titanium is an important structural metal, which has the characteristics of high strength, good corrosion resistance and high heat resistance. It is widely used in making aircraft engine compressor parts, as well as various structural parts of rockets, missiles and aircraft.
Introduction to titanium and titanium alloy materials
Titanium is an important structural metal developed in the 1950s. Pure titanium is a silvery white metal with active chemical properties and many excellent properties. Titanium alloy is an alloy composed of titanium and other elements. Titanium alloy has the characteristics of high strength, good corrosion resistance and high heat resistance.
Titanium alloy parts manufactured by 3D printing technology have very high strength, accurate size and better mechanical properties than forging process. Because of its good biocompatibility and excellent mechanical properties, titanium alloy is mainly used in biomedical materials, aerospace, precision instruments and so on.
Titanium alloy has the following excellent characteristics.
1. High specific strength. The density of titanium alloy is only 60% of that of steel. The strength of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength / density) of titanium alloy is much greater than that of other metal structural materials, and parts with high unit strength, good rigidity and light weight can be manufactured.
2. High thermal strength. The service temperature of titanium alloy is several Baidu higher than that of aluminum alloy, and it can work for a long time at the temperature of 450 ℃ ~ 500 ℃. The working temperature of aluminum alloy is below 200 ℃.
3. Good corrosion resistance. Titanium alloy works in humid atmosphere and seawater, its corrosion resistance is much better than stainless steel, and its resistance to pitting corrosion, acid corrosion and stress corrosion is particularly strong.
4. Good low temperature performance. Titanium alloy can still maintain its mechanical properties at low temperature. For example, TA7 can maintain a certain plasticity at - 253 ℃. Therefore, titanium alloy is also an important low temperature structural material.
02. Application of titanium and titanium alloy materials
1. Biomedicine
Titanium alloy has been widely used in the medical field because of its good biocompatibility and corrosion resistance. It has become the preferred material for medical products such as artificial joints, bone trauma, spinal orthopedic internal fixation systems, surgical instruments and so on. The implanted titanium alloy material with 3D printing can be personalized designed according to different personal requirements. For example, the mandible made with 3D printing technology can fully fit the patient's affected curve. Titanium is known as the best metal material with biological properties. Its market demand in the medical field of 3D printing will continue to expand and its application prospect will be broad.
In 2011, researchers at the Biomedical Research Institute of Hasselt University in Belgium developed a metal mandible and installed a customized titanium alloy mandible for an 83 year old woman using a 3D printer manufactured by layerwise company. This is the first operation of this type in the world, marking the beginning of clinical application of 3D printed grafts.
2. Aerospace
Since the 1950s, titanium alloys have developed rapidly in the field of aerospace. This application mainly utilizes the excellent mechanical properties, low density and good corrosion resistance of titanium alloy. Titanium alloy is one of the main structural materials of contemporary aircraft and engines. The components of cockpit and ventilation duct, aircraft landing gear support, wing and other aircraft components can be produced by 3D printing.
3. Automobile manufacturing
Automobile parts made of titanium and titanium alloy can save fuel, reduce engine noise and improve service life. A British company successfully printed auto parts such as impeller and turbocharger with titanium powder.
4. Other areas
Titanium alloy has been widely used in bicycles, tennis rackets and golf clubs because of its excellent properties. 3D printed titanium alloy objects have unique advantages in sports equipment because of their low density, high strength and lighter weight. For example, the golf head made of titanium alloy can hit accurately and far than the golf head made of ordinary stainless steel.
Titanium is easy to anodize into various colors, which makes it widely used in watch and jewelry industry. The picture shows the watch made by rvndsgn team using 3D printing technology. The main shell, frame and strap accessories of the watch are made by 3D printing SLS (selective laser sintering). Fine texture is formed during sintering, showing the difference from medium gray to dark gray.
