🏭 What I Do — From Industry's Perspective
I solve hard manufacturing and materials challenges that sit at the boundary of what can be designed and what can be physically built. My work centres on three industrial problem spaces:
| Problem | What I Bring |
|---|---|
| You need complex, lightweight structures that outperform solid or conventionally-latticed parts | Computational design + 3D printing of TPMS metamaterials (Gyroid, Schwarz-P, Diamond) in metal and high-performance polymers |
| Your material behaves unexpectedly after AM processing — cracking, porosity, phase shifts | Hands-on LPBF process optimisation + full SEM/XRD/DSC characterisation pipeline to diagnose and resolve root causes |
| You need smart, adaptive components — actuators, stents, morphing structures — without motors or electronics | Shape Memory Alloy (NiTi, Cu-Al-Mn, Cu-Al-Ni) fabrication, characterisation, and functional testing |
Availability: Open to collaborative research, industrial R&D consultancy, and joint project proposals. → contact@shahadathussain.com
