IIT Madras setting & why Fabheads matters now
Host Amrit introduces the show from IIT Madras and frames Fabheads as a recent breakout deep-tech manufacturing story. Dhinesh is introduced as founder/CEO, with the conversation aimed at demystifying additive manufacturing in composites and what it takes to build hard tech in India.
What Fabheads builds: automated manufacturing for composite parts
Dhinesh explains Fabheads’ core focus: making high-performance composite components (carbon fiber, Kevlar, glass fiber) using a more automated process. The problem is that today’s composite fabrication is still heavily manual despite composites becoming the default material for high-performance applications.
Additive vs subtractive: why composites are different (anisotropy & fiber direction)
The discussion contrasts subtractive/reductive manufacturing (machining, milling, lathe) with additive approaches. Dhinesh explains why composite parts can’t be treated like isotropic metals/plastics: fiber directionality (anisotropy) determines strength, so manufacturing must precisely place fibers.
The hidden reality: aircraft, wind blades, rockets—still handcrafted composites
Dhinesh highlights how surprisingly manual composite manufacturing remains even for world-class products. From Boeing structures to wind turbine blades to ISRO rockets and LCA Tejas, large composite structures often rely on technicians laying up fibers by hand, creating scaling and quality constraints.
Fabheads’ approach & positioning: one of a handful globally
Fabheads has developed an automated composite additive manufacturing capability and claims to be among only a small number of companies worldwide doing this at high capability levels. Dhinesh emphasizes strategic importance: some advanced manufacturing tech can’t simply be imported, making indigenous capability critical.
What they deliver today: machines, but mainly Manufacturing-as-a-Service (MaaS)
Rather than selling machines broadly, Fabheads mostly runs a manufacturing-as-a-service model—building parts for customers in its own facilities. They selectively place machines in academia (including IIT Madras) to evangelize the technology and grow a talent and user ecosystem.
From “3D printing” to “additive manufacturing”: a composites-first perspective
Dhinesh argues composites have been “additive” since the 1920s because traditional layup is inherently layer-by-layer. The conversation reframes 3D printing as only one subset of additive manufacturing and uses filament winding (pressure vessels/CNG tanks) as a classic composite additive process.
Why it took years: building both the material and the machine (two startups in one)
Dhinesh explains the long R&D runway: the machine required a new form of material feedstock that didn’t exist off-the-shelf, so the team had to invent material processing first, then the machine. With a tiny team and heavy iteration costs, reaching an MVP took about four years.
Funding reality for deep tech: convincing engineers, surviving the pandemic
The first meaningful investment came from angels with industrial/hardware context, who could accept multi-year timelines unlike typical software investors. COVID forced a survival phase with services/consulting, followed by a bridge round and then market entry only in the last ~2.5 years.
Founder journey: IIT Madras composites roots → NAL → ISRO → startup leap
Dhinesh traces his path: early hands-on work at CFI building a “vacuum blimp” introduced him to composites’ manual pain. Exposure deepened at NAL during LCA Tejas work and later at ISRO, where he repeatedly saw quality/rejection and scaling issues—ultimately motivating Fabheads.
Why India must own additive composite tech: scale, reliability, and defense needs
The conversation emphasizes national capability: India’s drone mission, aerospace, and defense ambitions require scalable composite manufacturing beyond artisan-level craftsmanship. Automation is positioned as essential for meeting demand, reducing rejection, and building strategic independence.
What $10M enables: scaling from R&D to a full production factory
Dhinesh shares details of the new funding round and how it will be deployed. The core spend is on creating a larger-scale manufacturing facility in Bangalore, moving beyond a small Chennai R&D/mini-production setup into industrialized output.
Future of advanced manufacturing: composites adoption driven by safety + efficiency
Dhinesh predicts composites will expand rapidly across sectors because of lightweighting, corrosion resistance, and safety benefits. Examples include F1 crash safety, evolving vehicle safety standards, and the shift away from metal cylinders in Europe—trends likely to spread as manufacturing becomes automated and cheaper.
Why additive wins in composites: speed vs legacy manual processes + new applications
The host contrasts metal/plastic additive’s common drawback—speed—against composites, where the baseline is slow manual labor. Dhinesh argues automation in composites can be faster and more economical than incumbent processes, enabling expansion into areas like customized biomedical implants.
Builder mindset: perseverance with flexibility + closing reflections
Dhinesh closes on the personal side of building hard tech: perseverance matters, but so does adapting strategy (including business model shifts) based on market feedback and funding realities. The episode ends with reflections on IIT Madras as a formative “best place to build” environment and a final call to learn more about Fabheads.
