Why in News?
The Akasha300 is in the news following its first commercial delivery to ISRO’s Liquid Propulsion Systems Centre (LPSC) in Valiyamala, Thiruvananthapuram, on March 23, 2026.
Key Information
- Developed by the Kerala-based deep-tech startup Spacetime 4D Printing Solution, a startup founded in 2020 by Akhil Madhavan and his team. This delivery marks a major milestone in the "Atmanirbhar Bharat" initiative, as it provides ISRO with a domestically produced platform for high-performance additive manufacturing.
- Technological Support: The project was backed by the Space Technology Innovation and Incubation Centre (STIIC) at the Indian Institute of Space Science and Technology (IIST) and the Kerala Startup Mission (KSUM).
- High-Temperature Capability: The printer features a nozzle capable of reaching 350°C (upgradeable to 500°C), allowing it to process engineering-grade thermoplastics and composites like PEEK, PEKK, and carbon-fibre-reinforced materials.
- Dual-Extrusion System: It utilizes a dual-extrusion setup, enabling multi-material printing—such as simultaneous printing of a high-strength part and its soluble support structure.
- Controlled Thermal Environment:
- Heated Bed: Reaches 110°C (upgradeable to 150°C) to prevent warping.
- Enclosed Chamber: Maintains temperatures up to 80°C for dimensional stability.
- Modular Architecture: Designed as a research platform, its modular extruder allows for future integration of additional systems or hybrid manufacturing techniques.
- Aerospace Applications: ISRO will use the Akasha300 to rapidly prototype and manufacture complex components for next-generation rocket propulsion systems and satellite hardware.
- Significance: By producing these high-end printers locally, India reduces its reliance on expensive imports from the US and Europe while shortening development cycles from months to days.
