Before joining Infinita Lab, Rahul held R&D roles at two early-stage startups, focusing on additive manufacturing, materials characterization, and developing application-specific material solutions. Additive manufacturing in a startup context means owning the full loop — feedstock qualification, print-parameter development, post-processing protocol, characterization strategy, and qualification framework — without the safety net of an established materials database or a captive lab. That kind of R&D pressure trains a specific skill: the ability to ask the right characterization question first, because the project does not have a budget for the wrong one. Most additive manufacturing failures are not print failures; they are characterization-strategy failures upstream.... Read More
