China3D printingNet September 29 news, solid metal3D printingExpert Fabrisonic used its patented Ultrasonic Additive Manufacturing (UAM) process to successfully fuse different amorphous alloys into the multi-metal coating.
As part of NASA’s SBIR research, the company deployed ultrasonic energy instead of traditional laser-based3D printingMethod to combine different corrosion-resistant alloys. Using its proprietary manufacturing technology, Fabrisonic is able to connect metal to the crystal substrate without destroying any of its beneficial properties.
The resulting metal mixture has higher strength and corrosion resistance than ordinary crystalline alloys, which may make it very suitable for future cladding applications in the aerospace industry.

Fabrisonic’s ultrasonic additive manufacturing technology
Fabrisonic’s UAM technology is a mixed metal3D printingProcess, a series of metal strips can be ultrasonically welded into a 3D shape. The method operates at low temperatures, which allows dissimilar materials (such as electronic products) to be embedded in metal alloy structures.
With the accumulation of metal objects, CNC machines can also be used to finish their inner and outer surfaces, which is similar to traditional metal3D printingCompared with craftsmanship, users can create more detailed shapes. Since the company applied for a patent for its UAM printing technology in 2017, it has been releasing its SonicLayer 1200 device, which also has its UAM technology.
In order to find patented3D printingFor new applications of technology, Fabrisonic has established partnerships with many US government research institutions in recent years.The company worked with Oak Ridge National Laboratory (ORNL) to deploy UAM to ORNL’s High Throughput Isotope Reactor (HFIR)3D printingControl panel.
Fabrisonic has also established a close relationship with NASA. They jointly developed3D printingThe heat exchanger equipment passed the aerospace quality control test in 2018. Recently, the company collaborated with optical sensor expert Luna Innovations to produce sensors for NASA. The project aims to collect data on cryogenic fuel pipes for the rocket test rig at Stennis Space Center.
In the latest collaboration between NASA and Fabrisonic, the latter has further developed its UAM process to print composite metal coatings, which may be used in aerospace in the future.

Better use of amorphous metals
Amorphous metal or bulk metallic glass (BMG) is formed by rapidly cooling the alloy to bypass the crystallization stage of solidification. As a result, the materials have a unique disordered structure, and they have higher strength than conventional crystalline alloys.
BMG can also withstand greater reversible deformation than other metals, and they lack long-term periodicity, so they are also more resistant to corrosion. Although amorphous metals clearly have advantageous manufacturing characteristics, they have previously proven difficult to combine with other materials and difficult to print in thicker layers.
Fabrisonic and LM Group Holdings (LMGH), a partner of the National Aeronautics and Space Administration (NASA), tried to use its UAM 3D printingThe process fuses amorphous metals with other alloys to overcome these limitations. The company proved the feasibility of the process by adding several different amorphous alloys and studying the reaction to better understand the interface composition.
Fabrisonic’s UAM process (as shown in the picture) allows different metals to be combined without losing any of their corrosion resistance. Picture from Fabrisonic.
During the test, the research team found that the low temperature of UAM resulted in almost no intermetallic formation of the combination of dissimilar metal alloys, and did not reduce its high-strength characteristics. The two companies also discovered that multiple passes can be used to add more metal, which in turn allows the thickness of the structure to be tailored to the end use.According to China3D printingWang understands that low ductility is usually a problem with existing crystalline alloys, but considering that UAM is compatible with a variety of materials, it can add more ductile metals to the mixture. Similarly, traditional welding techniques limit BMG to specific geometries, but evaluations show that UAM can now be used to achieve more complex 3D shapes at a lower cost.
Overall, in the first phase of NASA’s development plan, the partners managed to incorporate crystalline metals such as aluminum, titanium, and steel to produce parts with a wall thickness of 1mm.In the future,3D printingThe technology is deployed in the creation of laminates for heavy equipment or insulated oil and gas pipelines.
China3D printingOnline reviews: LMGH and Fabrisonic can provide a generation of products and services that are more advanced than the current state-of-the-art technology. Significant advantages in substrate protection, extended service life and improved application efficiency.
