On Friday, May 10, the Indian Space Research Organisation (ISRO) added another feather to its cap by successfully conducting a hot test of a liquid rocket engine manufactured using Additive Manufacturing (AM) technology, also known as 3D printing. This groundbreaking achievement underscores ISRO’s commitment to innovation and technological advancements in the realm of space exploration.
The successful test of the 3D-printed rocket engine showcased several significant improvements. Firstly, the Laser Powder Bed Fusion technique employed in its construction dramatically reduced the number of parts required from 14 to just 1, greatly simplifying the production process and enhancing reliability. Secondly, the elimination of 19 weld joints through 3D printing further improved the engine’s durability and performance.
Additionally, the reduced part count and elimination of weld joints resulted in substantial savings in raw material usage per engine, leading to increased cost efficiency. This breakthrough in engine design and manufacturing holds promise for future space missions, enabling ISRO to optimize its resources and push the boundaries of space exploration.
ISRO’s success in developing and testing the 3D-printed rocket engine marks a watershed moment in India’s space program, paving the way for more efficient and advanced space exploration endeavors. The organization’s dedication to technological innovation and its commitment to pushing the frontiers of space research continue to inspire and empower the nation’s scientific community.
