China3D printingNet April 9th, the Italian Additive Manufacturing Service Agency BEAMIT has developed a new titanium alloy Ti62423D printingProcess, this process can produce better performance than similar products made in traditional manufacturing, and is an ideal component for aerospace and motorsports.
BEAMIT’s laser powder bed fusion (LPBF)3D printingThe process can produce components with similar levels of tensile strength and temperature resistance from other materials, but they are much lighter in weight. According to the company, its newly developed process can also achieve sustainable benefits through waste prevention and powder recycling.
Andrea Scanavini, General Manager of BEAMIT Group, said: “Our hard work is essentially positioning ourselves at a level where we can make technological innovations and change the rules of the game to apply3D printingapplication. We are very concerned about customer needs and productivity, and use our materials and process engineering department to provide turnkey solutions for next-generation production processes. “

3D printingTitanium alloy Ti6242
After conducting in-depth research and exploring alloys suitable for LPBF processing, BEAMIT began to develop its Ti6242 additive manufacturing process in 2019. The company chose Ti6242 for its ability to withstand high temperatures and produce lightweight components without affecting its tensile strength. This makes the alloy an ideal choice for applications where lightweight and high-performance components are critical in the racing and aerospace industries.
The BEAMIT team set out to optimize the mechanical properties of Ti6242l at temperature through the LPBF process, thereby achieving a tensile strength of up to 1,000 MPa and a density of 4.5 g/cm3.
Alessandro Rizzi, Material and Special Process Manager of BEAMIT Group, said: “The development of the Ti6242 process started in 2019 as part of the collaboration with the Politecnico di Milano. The material is perfectly suitable for LPBF, but our real focus is on heat treatment. We have designed different vacuums. Cycle to optimize its mechanical properties at room temperature and high temperature, and developed an integrated high-pressure heat treatment process.”
As a result, Ti6242 alloy has a high strength-to-weight ratio of over 600 MPa at temperatures up to 550°C, which makes it an attractive choice for applications requiring good mechanical strength and lightweight, and is a super alloy of steel and nickel. Viable alternatives. The BEAMIT team conducted a test to compare3D printingThe mechanical properties of Ti6242 and Ti6242 and another high-performance titanium alloy IMI834 produced by conventional methods (such as forging).
According to China3D printingThe net understands that this3D printingThe performance of components is better than that of components forged by traditional technology. This process has consolidated the role of additive manufacturing at the forefront of material development in industries such as automotive and aerospace. The company also praised this technology as representing a “revolution” in sustainability, reducing waste by using only necessary materials and recycling the remaining powder for future projects.
“Research and development of new materials has always been the foundation of the BEAMIT Group, and we are proud to be the only company that can provide first-class technical solutions in the market, especially in the fields of racing, automotive and aerospace,” Giuseppe Pisciuneri, Chief Commercial Officer of BEAMIT . “Being a pioneer in this innovation and using our materials in new projects for customers will inspire us to continue to develop and inspire us to do bigger and better things.”

The development of titanium alloys
Due to its ideal strength and weight characteristics, the demand for high-temperature titanium alloys in the automotive and aerospace fields is increasing. However, the engineering weight ratio, complex structure, working temperature and development speed of titanium alloys pose challenges to traditional manufacturing processes. As a result, for manufacturers in these fields,3D printingIs quickly becoming an interesting choice.
Regarding cars, luxury car manufacturer Bugatti has integrated in some of its vehicles3D printingTitanium parts, including exhaust tailpipes for Chiron Pur Sport models to reduce weight and improve the high temperature resistance of the parts, and titanium alloy mounting brackets for the wing of the Bolide super sports car at the front.
At the same time, 1016 Industries, a car modification expert, has combined titanium and carbon fiber3D printingFused together to combine3D printingThe performance components of the McLaren 720S are integrated into the one-time ultra-lightweight version of the McLaren 720S sports car. Thanks to this technology, the weight of the special edition model is nearly 9% lighter than the original model.
Aerospace3D printingSignificant progress has also been made in the development of titanium materials. For example, SLM and SLS 3D printingMachine manufacturer Farsoon Technologies announced the development of a new high-temperature titanium material TA32 from its customer Aerospace Hiwing Titanium Industrial Co. (AHTi), which is specifically used for FS271M 3D printingsystem. Parts printed with this alloy can withstand a maximum operating temperature of 550 degrees Celsius, and have excellent tensile strength, flexibility and plasticity mechanical properties at high temperatures.
