Abstract:

Laser additive manufacturing (LAM) is a mainstream 3D printing technology that creates 3D objects layerwise using a high-energy laser beam. LAM offers design freedom and manufacturing flexibility for processing high-performance materials and complex geometries. Materials, structure, process, and performance are critical aspects to advance LAM. To leverage the unique metallurgy behaviour, materials distribution flexibility and geometry complexity capability of LAM, this report will highlight materials design for LAM, complex structures manufacturing, and innovative LAM processes to recap the frontier R&D findings. The main content includes: (i) Machine learning assisted material customization for LAM, (ii) heterogeneous materials and structures, and (iii) innovative LAM processes with coaxial wire feeding or auxiliary energy fields. The future perspectives on R&D in additive manufacturing are also outlined.
