In a landmark moment for India’s growing deep tech ecosystem, Thiruvananthapuram based startup Spacetime 4D Printing Solution has successfully delivered its flagship product, the Akasha300, to the Liquid Propulsion Systems Centre (LPSC) at Valiyamala — one of the most critical research and development facilities under the Indian Space Research Organisation (ISRO). This achievement signals not only a significant milestone for the young company but also a broader advancement in India’s pursuit of indigenous high performance additive manufacturing technologies.
A Product Built for Demanding Environments
The Akasha300 is not a conventional 3D printer. Engineered specifically for advanced research and industrial applications, it is a high temperature, multi material extrusion system designed to operate where standard manufacturing tools fall short. Its dual extrusion architecture supports printing temperatures of up to 350°C, with an upgrade path extending to 500°C — a specification that opens the door to processing some of the most demanding engineering grade polymers and composite materials available today.
Supporting this is a carefully controlled thermal environment. A heated bed capable of reaching 110°C, upgradeable to 150°C, combined with an enclosed chamber that maintains temperatures of up to 80°C, ensures consistent material behaviour and dimensional accuracy throughout the printing process. These are not incremental improvements — they represent the kind of precision that aerospace and defence grade applications demand.
The system’s modular extruder architecture is equally noteworthy. By enabling future hardware upgrades and hybrid extrusion approaches, the Akasha300 is designed to evolve alongside emerging materials science, making it a long term research asset rather than a static instrument.

Rooted in Kerala’s Innovation Ecosystem
This milestone did not emerge in isolation. Spacetime 4D Printing Solution has benefited considerably from the support of the Space Technology Innovation and Incubation Centre (STIIC) at the Indian Institute of Space Science and Technology (IIST), as well as the Kerala Startup Mission. The startup also received a significant vote of confidence when Prof. Dipankar Banerjee, Vice Chancellor of IIST, along with mentor Prof. K G Sreejalekshmi, visited the company and reviewed the Akasha300 firsthand.
What This Means for Indian Manufacturing
The delivery to LPSC carries implications that extend well beyond a single transaction. LPSC is the nodal centre responsible for the development of liquid propulsion systems for Indian launch vehicles and spacecraft — a domain where material performance, geometric precision, and reliability are non negotiable. Introducing an indigenously developed, research grade additive manufacturing platform into this environment reflects a maturing confidence in homegrown engineering solutions.
For a country that has long relied on imported advanced manufacturing equipment, this development represents a meaningful step toward self reliance in a strategically sensitive sector. Spacetime 4D’s journey from founding in 2020 to delivering to one of ISRO’s key centres, demonstrates what focused engineering ambition, institutional support, and a conducive startup ecosystem can achieve within a remarkably short timeline.
The road ahead will involve proving the Akasha300’s capabilities at scale, expanding its material compatibility, and potentially extending its reach to other research institutions and industries. But this first delivery is a foundation worth building upon and a reminder that India’s next generation of deep tech innovation may well emerge from its own backyard.
