3d printing metal

3-D printing in space is not new. Since 2014, the International Space Station (ISS) crew has used many 3-D printers to replace plastic parts. However, crew autonomy is increasingly critical as exploration missions lengthen—and metal part…

A research team from the National University of Singapore (NUS) has developed a cutting-edge technique called tension-driven CHARM3D to fabricate three-dimensional (3D), self-healing electronic circuits. This new technique enables the 3D…

There’s now a metallic gel that is highly conductive and can be used to print three-dimensional (3D) solid objects at room temperature—in a single step. This potentially opens up the ability to manufacture a wide range of electronic…

Washington State University researchers created a way to 3D-print two types of steel in the same circular layer using two welding machines. The bimetallic material is 33% to 42% stronger than either metal alone. The method uses common,…

A research team at the Department of Joining Technology of the Korea Institute of Materials Science (KIMS) developed a foundational technology to control the volume of molten metal in the process of 3D printing metal using welding. They…

Structural defects that form during an additive manufacturing building process have prevented its wide adoption. Researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory developed a new method to detect and predict…

Strength and durability are paramount for nuclear power plants and various critical technologies, so many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening (PH) stainless steel. Now 17-4 PH steel…
