The Indian Space Research Organization (ISRO) on Friday, May 10, registered another milestone in its list of success stories with the development of additive manufacturing (AM) technology, also known colloquially as 3D printing. A hot test of the created liquid rocket engine was successfully conducted. ,
Let’s take a look at the top 7 points about 3D-printed rocket engines:
- The engine the space agency tested is the PS4 engine used in the Reaction Control System (RCS) of the upper stage (PS1) of the Polar Satellite Launch Vehicle (PSLV).
- According to ISRO’s statement, the same engine is also used in the Reaction Control System (RCS) of the first stage (PS1) of PSLV.
- The test was conducted at ISRO Propulsion Complex, Mahendragiri in Tamil Nadu on Friday.

- As a result, the new engine now saves 97 percent of raw materials and reduces production time by 60 percent.
- The traditional manufacturing process now requires a total of 13.7 kg of metal powder compared to the 565 kg of forgings and sheets previously required.
- “ISRO achieved major milestone with successful hot test of liquid rocket engine manufactured through AM technology for a duration of 665 seconds on May 9,” a press release from the space agency said.

- Highlighting this success, the space agency also took to social media platform X (formerly Twitter). The post reads, “Success in Design and Manufacturing: ISRO successfully conducted long-term testing of the PS4 engine, which was redesigned and prepared in Indian industry for production using state-of-the-art additive manufacturing technologies.”

The space agency said that after the successful administration of the test, the number of deployed parts has been reduced from 14 to 1 using laser powder bed fusion technology. This eliminated 19 weld joints, resulting in significant savings in raw material usage per engine.
