Chennai's ThinkMetal Raises ₹27 Crore to Take Filament-Based Metal 3D Printing to Industry
Chennai's ThinkMetal has raised ₹27 crore in a round led by IAN Alpha Fund. It will use the money to move its SistemT1 metal 3D printer and FuseX metal filament from pilots to aerospace, defence and mobility customers.
ThinkMetal, a Chennai start-up working on advanced materials and manufacturing, has raised ₹27 crore (about $2.84 million). Reports of the round appeared on 13–14 October 2026. IAN Alpha Fund, part of the Indian Angel Network group, led the round. The deep-tech investor 3i Partners and existing investors also took part. The company did not disclose its valuation or how much each investor put in.
Some reports give a dollar figure of $3.2 million. The ₹27 crore figure is the same everywhere, and about $2.84 million is the correct conversion at current exchange rates.
What ThinkMetal makes
The company's main product is SistemT1, an industrial metal 3D-printing system. It runs on FuseX, ThinkMetal's own metal filament.
That puts ThinkMetal in a specific corner of additive manufacturing. Most industrial metal 3D printing uses powder-bed fusion: a laser or electron beam melts thin layers of fine metal powder inside a sealed, inert-gas chamber. The method produces excellent parts, but the machines are expensive, the powders need careful handling, and the process needs a specialised facility.
Filament-based metal printing works more like a desktop plastic printer:
- A filament made of metal powder bound in a polymer is laid down layer by layer.
- The printed part is put through debinding, which removes the polymer.
- The part is then sintered, which fuses the metal powder into dense metal.
The equipment is usually simpler and safer to run. The trade-offs are the extra post-processing steps and some limits on part size and properties.
ThinkMetal is aiming at aerospace, defence, space, automotive and electric-mobility customers. These sectors often need small batches of complex metal parts, such as brackets, fixtures, prototypes and replacement components. Conventional machining or casting can be slow and costly for those parts.
The claims, and the caution
Rajnish Kapur of IAN Alpha Fund said the platform could make precision metal parts up to 10 times faster and at half the cost. That is the investor's claim. We have not seen independent benchmarks, and such figures usually depend on the part and the method being compared.
What the money is for
ThinkMetal says the funding will move it from early technology development and enterprise pilots to wider commercial use. It will spend on:
- product development and R&D
- growing the team
- getting more industrial customers to adopt the system
The company was founded in 2021 by Sabyasachi Ghosh and Arushi Sharma.
Why it matters for India
Metal additive manufacturing is a strategic capability. Defence and space programmes increasingly use 3D-printed engine parts, brackets and tooling, and Indian launch-vehicle start-ups have printed rocket engines. Most of the machines and much of the feedstock behind that work are imported.
A home-grown printer with its own filament gives Indian manufacturers a domestic option for both the machine and its material. That can lower costs. It also reduces exposure to export controls and the supply risk that comes with imported strategic equipment.
The round is small by global standards. But it brings Indian capital into hardware where Indian engineers own both the machine and the material. Watch next for whether ThinkMetal's pilots with aerospace and defence customers become repeat orders.
