The NIST Metal Additive Manufacturing (AM) Research Facility includes two commercial metal-based AM systems located in two different buildings on the main NIST campus. These systems build parts from metal powders using two different additive manufacturing processes: Direct Metal Laser Sintering (DMLS), a type of powder bed fusion process, and Binder Jetting (BJ), a process in which a liquid bonding agent is selectively deposited to join powder materials.
The DMLS system has the capability to build parts from stainless steel, aluminum, titanium alloy, nickel alloy, and cobalt-chrome powders in either a Nitrogen or Argon environment (the argon environment at NIST is still in development). This system has the following features:
The BJ machine has the capability to build parts from stainless steel, bronze, and tungsten powders in an atmospheric environment. This system has the following features:
NIST research in this facility is focused on developing measurement science solutions for characterizing powders, processes, machines, and manufactured parts, as well as introducing process monitoring and control methods to improve the quality and reproducibility of the parts resulting from the processes.
