India’s space agency, the Indian Space Research Organisation (ISRO), has successfully tested a revolutionary innovation – a rocket engine built using 3D printing technology, also known as additive manufacturing. This achievement marks a significant milestone in ISRO’s journey and holds immense potential for the future of space exploration.

What is the 3D-Printed Rocket Engine?
The tested engine is the PS4, which powers the fourth stage of ISRO’s workhorse launch vehicle, the Polar Satellite Launch Vehicle (PSLV). Traditionally, the PS4 engine was manufactured using multiple parts assembled together. However, ISRO’s engineers redesigned the engine specifically for 3D printing.
How Does 3D Printing Work in Rocket Engines?
3D printing works by building an object layer by layer using a digital blueprint. In ISRO’s case, they most likely used a technique called Laser Powder Bed Fusion. Here’s a simplified breakdown:
- Metal Powder Preparation: A fine metal powder is used as the building material.
- Laser Melting: A powerful laser beam selectively melts the metal powder, creating each layer according to the digital design.
- Layer-by-Layer Building: The laser precisely adds each layer on top of the previous one, gradually forming the complete engine structure.

Benefits of 3D-Printed Rocket Engines:
This innovative approach offers several advantages over traditional manufacturing:
- Reduced Parts and Weight: The 3D-printed engine is a single piece, reducing the need for multiple parts and weld joints. This leads to a lighter engine, crucial for improving a rocket’s payload capacity. ISRO estimates a weight reduction of a huge 97% compared to the conventional method.
- Faster Production: 3D printing significantly reduces production time. ISRO reports a 60% decrease in manufacturing the PS4 engine. This translates to faster launch vehicle turnaround times.
- Efficient Material Usage: With 3D printing, material is used only where needed. ISRO highlights a 97% saving in raw materials compared to traditional methods. This translates to cost savings and reduced environmental impact.
- Complex Design Freedom: 3D printing allows for Complex designs that might be difficult or impossible with conventional techniques. This opens doors for future engine optimizations.
The Road Ahead
The successful test of the 3D-printed PS4 engine is a major accomplishment for ISRO. It demonstrates India’s growing expertise in additive manufacturing and its potential to revolutionize spacecraft design and development. This technology has the potential to not only improve existing launch vehicles but also pave the way for the creation of next-generation rockets and spacecraft.
