In dental 3D printing, Ti6Al4V (Ti-64)is often used because it produces highly accurate parts with a smooth surface finish, which are also biocompatible. It is one of the most widely used titanium alloys for a variety of applications such as aerospace and medical implants due to its high strength-to-weight ratio, excellent corrosion resistance and superior fatigue strength.
Titanium (Ti) makes up 95% while the remaining 5% is made up of small amounts of aluminum (Al) and vanadium (V). This titanium alloy typically contains 6% aluminum and 4% vanadium in order to improve its strength and hardness. The titanium atoms in this alloy form a continuous lattice structure called the alpha phase which provides superior characteristics such as higher tensile yield strength, creep resistance, toughness and fatigue strength.
The titanium alloy has a high melting point which makes it suitable for applications that require working temperatures up to 800°C. Additionally, its excellent corrosion resistance allows it to be used in harsh environments without requiring additional protective coatings or treatments. This feature also makes it suitable for use in medical implants where long-term performance is important. Furthermore, the titanium alloy’s low modulus allows for greater flexibility when forming complex shapes which makes it ideal for dental 3D printing applications.
In terms of mechanical properties, titanium alloys are extremely strong compared to other metals with similar weight values and have a higher tensile yield strength than stainless steel alloys when tested at room temperature. It also has good ductility which makes it easier to fabricate parts that require complex shapes such as dental implants or bridges. The combination of high strength and ductility make titanium alloys an ideal material for use in dental 3D printing where accuracy is essential for precise fitting implants or bridges.
In summary, Ti6Al4V (Ti-64) is an excellent material choice for dental 3D printing thanks to its properties including high tensile yield strength, corrosion resistance and excellent fatigue properties leading to precise parts with a smooth surface finish at lower costs compared to alternative materials such as stainless steel or cobalt chrome alloys making them biocompatible with human tissue with no extra coating required yet still strong enough to hold out over time even under stress conditions applied by human jaw movements during chewing making them last longer than alternative solutions providing better overall value over time being cost effective while still providing quality durable results when printed right making them cost effective solution compared to other alternatives available on the market today making them attractive choice even in cases where alternative solutions are available due their unique combination of physical properties making them go-to solution when dealing with precision requirements during 3d printing operations within dentistry field today .
