We all know by now how important additive manufacturing will one day be within space travel and exploration. One company called MTI may have just moved the needle a bit in the world of laser sintering, when considering applications within space. They have successfully 3D printed with a Niobium alloy called C-103. They managed to turn the alloy into a powder which was then able to be printed with via a 3D Systems ProX 300 machine. Potential uses of the alloy include parts which need to stand up to extreme temperatures, both hot and cold, as well as being light in weight.
