The Akasha300 3D Printer is an advanced, industrial-grade high-temperature additive manufacturing system developed by Spacetime 4D Printing Solution and recently delivered to the Liquid Propulsion Systems Centre of Indian Space Research Organisation. Designed for manufacturing complex aerospace components, the printer can operate at temperatures up to 500°C, enabling the use of high-performance polymers and composites required for extreme space environments.
Supported by the Indian Institute of Space Science and Technology and Kerala Startup Mission, the innovation represents a major step toward Atmanirbhar Bharat in space technology.
What is Akasha300 3D Printer?
The Akasha300 is a high-temperature, multi-material extrusion 3D printer designed as a specialized industrial research platform. It is capable of processing engineering-grade thermoplastics and composite materials, which are essential for manufacturing spacecraft and propulsion system components.
Its dual-extrusion system allows simultaneous printing of two materials one for the core structure and another for support enabling complex geometries and precision engineering. This makes it highly suitable for aerospace R&D and advanced manufacturing applications.
