Challenges in laser additive manufacturing (Aug. 2014)

2D additive patterning and 3D components by laser layered additive manufacturing.

1. Photonic Integrated Circuit (PIC) fabrication by lasers;
2. Functional nano-structures (such as graphene, metamaterials) by laser additive manufacturing;
3. Laser additive manufacturing with blown powders: resolution, accuracy, distortion and surface finishing;
4. Multiple materials and multi-functional materials additive manufacturing;
5. Laser direct writing deposition: efficiency and throughput;
6. Deposition of electronics materials.
