Abstract Laser Additive Manufacturing (LAM) is recognized as an advanced manufacturing technology with integration
of precision forming and high-performance forming. Initially, principles and characteristics of two representative
LAM technologies are introduced respectively, following which the research developments of Xi’an Jiaotong University in
the field of LAM technology are emphatically introduced from the following aspects: (1) The effects of ultrasonic vibration
assisted laser cladding deposition process on the as-deposited microstructures and properties of IN718; (2) Repair of directionally
solidified DZ125L blades with DD4 by induction-assisted laser cladding deposition process; (3) The laser cladding
deposition process of CuW functionally gradient composite materials; (4) Effects of the purity of powder carrier gas on the
microstructures and properties of 40Cr repaired with Fe314 by laser cladding. Ultimately, the challenges that LAM technology
may confront with are explained.
