Micro-deposition of Cu-based metallic glass wire by direct laser melting process

•CuZr binary metallic glass micro-wires were synthesized by melt-extraction method.•CuZr metallic glass layers were deposited using by direct laser melting technique.•Metallic glass melt can be 10 times easily spread out at high power laser deposition.•Micro-wire deposition is new approach to high-resolution additive manufacturing.
