- Additive manufacturing: laser processing, cost, speed (deposition rate and resolution), heat treatment, stress, distortion, & crack issues, surface finishing (inner surfaces), limited market size and structures’ quality on-line diagnostics (mainly technology and engineering challenges);
- Cutting of fiber composite materials (cutting speed, heat affected zone, cutting edge quality);
- Multi-scale laser processing: to apply microprocessing to macro scale;
- High power ultra-fast laser cold macro-machining;
- Welding of light alloy: porosity issue;
- Welding of dissimilar materials (composite materials);
- Multiple task laser processing (welding, hardening, cutting, deposition, drilling);
- Laser macro-processing based on micro/nano-materials;
- Glass processing (welding, cutting);
- Hybrid laser processing with other non-laser fabrication.
