The Indian Space Research Organisation (ISRO) achieved a significant milestone on May 10 by conducting a successful hot test of a liquid rocket engine manufactured using Additive Manufacturing (AM) technology, commonly known as 3D printing. The engine showcased several notable advancements:
– **Reduced Part Count:** By employing the Laser Powder Bed Fusion technique, the number of parts required for the engine was reduced from 14 to just 1, simplifying the production process.
– **Eliminated Weld Joints:** The 3D printing approach eliminated 19 weld joints, enhancing the engine’s reliability and durability.
– **Saved Raw Material:** The reduced part count and elimination of weld joints significantly reduced the raw material usage per engine, resulting in cost savings.
ISRO’s success in developing and testing the 3D-printed rocket engine marks a significant step forward in the advancement of India’s space exploration capabilities.
