About Company

ThinkMetal focuses on advanced materials innovation for manufacturing, with a strong emphasis on metal and alloy systems for additive manufacturing. We operate at the intersection of materials science, hardware, and process engineering, building integrated solutions that translate material capabilities into scalable, production-ready systems.

Our work spans metal and alloy development, feedstock engineering, and manufacturing setup design, enabling high performance, reliable, and repeatable industrial processes. We focus on taking materials from lab scale understanding to real world manufacturing deployment, particularly for metal based applications.

As part of the team, you will work in a highly hands-on environment with direct exposure to end-to-end product and process development, from concept and experimentation to production implementation.

Roles &

- Responsibilities

Role Overview: Develop and optimize polymer formulations for extrusion and additive manufacturing applications; troubleshoot processing problems; and translate research insights into practical, repeatable production processes.

Key Responsibilities

- Study thermal degradation behaviour and define safe processing windows for polymer blends.
- Evaluate compatibility and interfacial interactions in polymer blends. Convert research literature into practical experimental trials and improvements.
- Troubleshoot processing issues such as sticking, surging, melt fracture, and unstable flow.
- Optimize filament coating quality and dimensional stability.
- Oversee machine setup, alignment,



and process parameter standardization.
- Correlate Melt Flow Index (MFI) and rheology data with real extrusion behaviour.
- Interpret torque/load data during trials to estimate viscosity and flow characteristics.
- Perform FTIR and thermal observations to confirm degradation, additive interaction, and processing limits.
- Analyze filament properties including diameter consistency, surface quality, and green strength.
- Investigate defects such as bubbles, voids, cracking, delamination, and binder separation.
- Evaluate polymer coating uniformity, adhesion, and batch-to-batch consistency using comparative data.
- Conduct root-cause analysis using experimental testing and statistical comparison.
- Maintain experiment logs, SOPs, troubleshooting manuals, and knowledge-transfer documentation for internal teams.
