Vision of Fabheads: Fully Autonomous Composite Manufacturing

To lead the world in fully autonomous manufacturing: setting the standard for reliability, precision, and productivity.

Composite materials have been in serial production for decades. The processes used to manufacture them have not kept pace. Where most materials are now formed by automated systems producing consistent parts at scale, composites remain substantially manual: and closing that gap is what Fabheads was established to do.

For us that gap was never only a technical one. Self-reliance is the reason we started Fabheads: and the patents, the automation and the end-to-end capability were all built in service of that original intent.

The Automation Gap in Composite Manufacturing

In the 21st century, manufacturing processes for most materials are well established: completely automated, producing reliable and precise parts time after time. Composites are the exception. They remain one class of materials whose manufacturing still involves a great deal of labor-intensive work, and a great deal of time.

That is a strange place for the industry to be, because demand is going the other way. Aerospace, defence, drones, mobility and marine all want lighter, stronger parts, and composite materials are how they get them. The demand is growing; the manufacturing method has not kept pace.

Why Composite Parts Remain Expensive

Even today, a large number of composite parts (especially in MSMEs) are made by hand, because the machines that would automate the work cost more than a smaller manufacturer can justify. This is the main reason composite parts remain expensive.

It is not simply that the material is costly. The process is costly, because it consumes so much skilled manpower and so much time. And that cost is precisely why high-performance composite parts have not entered the mainstream market as widely as they should have.

The specific problems are well known to anyone who has run a layup shop:

• Human error and rejections. Manual processes like hand layup introduce variation, and variation means defects: which means higher rejection rates.
• Setup-heavy 'automation'. Processes such as resin transfer molding look automated, but the setup around them is still intensely manual.
• Material wastage. Preforms are cut from large fiber mats, and the offcuts are waste. On expensive material, that adds up quickly.
• Post-processing. Existing methods almost always need finishing work afterwards, adding both time and cost to every part.

Automated manufacturing is the way forward: but only if it genuinely solves the wastage and brings the cost of production down. Automation that simply moves the labor somewhere else is not worth having.

Our Automation Stack

Automating a production process reduces cost and increases reliability and repeatability. That much is well understood. What matters is how completely you automate it. What we built is what we call our Automation Stack: patented fiber composite layup machines and processes, in-house material processing, and proprietary software that ties the whole thing together.

At the centre of it is our continuous fiber printing technology (patented as Adaptive Tow Placement): a fully automated process for fabricating complete composite parts.

Continuous fiber printing needs only the 3D model of the part. It eliminates the need to draft drawings for the tool and for the component separately. And because it is purely additive, there is almost no material wastage: which, given how expensive composite material is, takes a significant cost out of the finished part.

The results are measurable. According to Accel, our automated fiber placement and layering technology cuts costs by up to 50%, reduces rejection rates by up to 20%, decreases material wastage by 20%, and accelerates production cycles by up to 30%.

Current Capability

Ambition is easy to state. What gives it weight is what has actually been built. Fabheads was the first company in Asia to develop in-house continuous fiber 3D printing capability, and our machines (the fabmachines range, including the F-Series, India's first indigenous continuous fiber 3D printer) are in production use rather than in development.

Accel, in announcing their investment, described Fabheads as one of only seven companies worldwide with commercial operations in patent-granted composite automation: and the only one from India. In June 2025 we raised a USD 10 million Series A to expand that work, including a new aerospace-focused facility in Bengaluru.

Alongside the machines, we run end-to-end composite manufacturing (design, analysis, tooling, prototyping and production) for customers across aerospace, mobility, marine and robotics. Building the automation and using it on real parts are not separate activities for us; each one teaches the other.

Building Domestic Capability

There is a particular reason this matters in India. Composite raw materials have long been export-controlled, but the dependency ran deeper than materials: the country lacked high-precision machinery, proprietary manufacturing processes, purpose-built software, and the sector-specific skilled people to run any of it. The result was that India either imported finished components or relied on foreign elements somewhere along the chain.

Building the whole chain in-house, and automating most of it, changes that. The processes are patent-protected and the software is our own, which means the technology stays here. An automation-first approach also addresses the skilled-labor shortage directly rather than competing for people who are not there.

Beyond that, highly composite-dependent industries such as aerospace and defence will operate differently once the manufacturing is automated. The most immediate change is inventory: automated processes make it viable to produce spare parts on demand, which means a large parts inventory no longer has to be held, financed and warehoused against a failure that may never come.

The second change is who gets access. When a composite part stops requiring a skilled layup team and weeks of lead time, it becomes an option for manufacturers who could never previously consider one. That is the difference between composites being a specialist material and composites being a default choice.

The Standard We Are Building Toward

We believe composites will become the go-to material in the mainstream market, not only in the industries that already depend on them. The manual processes in wide use today will not meet that demand: not at the volumes, the consistency or the price the mainstream requires.

So we are building the technologies that will. Fully autonomous manufacturing is not a slogan for us; it is a specification. Every generation of machine we build should need less human intervention, produce less waste, and hold tighter tolerances than the one before it. That is what leading the world in autonomous manufacturing has to mean in practice: measured in rejection rates and cycle times, not in press releases.

Frequently Asked Questions

Why was Fabheads started?

Self-reliance. India's aerospace and defence sectors depended on imported composite components, export-controlled raw materials, foreign precision machinery and foreign software. Fabheads was founded to build that capability domestically: and the patents, the automation and the end-to-end manufacturing were all built in service of that intent.

What is Fabheads' vision?

To lead the world in fully autonomous manufacturing: setting the standard for reliability, precision, and productivity. In practice that means automating composite manufacturing end to end, so that high-performance composite parts become affordable and repeatable enough for mainstream use.

Why is composite manufacturing still manual?

Because the machines that would automate it have historically been too expensive for most manufacturers, particularly MSMEs. As a result much composite work is still done by hand, which drives up cost, increases rejection rates through human variation, and wastes material when preforms are cut from large fiber mats.

How does automation reduce the cost of composite parts?

It removes manpower and time from the process, cuts material wastage because additive processes use only what the part needs, and reduces rejections by removing human variation. Accel reports that Fabheads' technology cuts costs by up to 50% and reduces wastage by 20%.

What is continuous fiber 3D printing?

A fully automated process that fabricates complete composite parts from a 3D model alone, laying continuous fiber into the part as it is built. It needs no separate tool drawings and produces almost no material wastage, unlike conventional layup.
