Agnikul Cosmos opens India's first large-scale aerospace parts additive manufacturing factory.

September 24, 2025 Applications 254

Agnikul Cosmos, a private space startup based in Chennai, India, has officially commenced operations at its large-scale additive manufacturing facility.

Agnikul Cosmos announced that its Large Format Additive Metal Manufacturing (LFAMM) division is equipped with India's largest aerospace-grade 3D metal printer and self-developed customized powder removal equipment. German industrial additive manufacturing leader EOS serves as a key partner for the project, providing advanced technology and equipment support.

Srinath Ravichandran, Co-founder and CEO of Agnikul Cosmos, emphasized: "We are not only committed to enhancing printing capabilities but also to developing full-scale additive manufacturing equipment in-house. This will significantly improve the efficiency of building our space transportation systems, accelerating both Agnikul's innovations and the progress of customer aerospace projects."

The new facility's capabilities will cover the entire additive manufacturing process chain, from design to finishing. Agnikul Cosmos stated that the metal additive manufacturing equipment in the new factory will be capable of printing components up to one meter in height. Although the specific model of this printer has not yet been officially announced, photographs from the inauguration ceremony appear to show an AMCM M 4K unit. This seems logical given the Indian company's partnership with EOS. AMCM, which stands for Additive Manufacturing Customized Machines, provides customized EOS systems tailored for specific applications and end-users.

Agnikul previously used the EOS M 400-4 system, which has a standard build volume of 400 x 400 x 400 mm. While substantial, this volume could not accommodate parts measuring one meter in length. However, the AMCM M 4K, an enhanced version based on the EOS M 400, offers an expanded build volume of 450 x 450 x 1,000 mm.

The inauguration ceremony for the new space facility was attended by Dr. V. Narayanan, Chairman of the Indian Space Research Organisation (ISRO) and Secretary of the Department of Space, along with Professor V. Kamakoti, Director of the Indian Institute of Technology Madras (IIT Madras). Ravichandran added, "Agnikul Cosmos was founded with the goal of making space accessible to everyone. One way to achieve this is by building capabilities that allow us to advance rocket manufacturing with precision while maintaining a strong focus on quality."

About Agnikul Cosmos

Founded in 2017 and incubated at the Indian Institute of Technology Madras (IIT Madras) – a public research university and institute of technology located in Chennai – Agnikul Cosmos has, in the following years, secured numerous investments and commercial agreements. The startup achieved a breakthrough in 2023 by successfully printing a flight-worthy engine. In 2024, Agnikul Cosmos successfully launched a rocket from its private launchpad. In August of this year, they showcased what is claimed to be the world's largest single-piece Inconel rocket engine, which also received a U.S. patent. This 3D-printed rocket engine can be manufactured in-house within a matter of days.
