Indian startup 3D prints rocket engine in 72 hours (spectrum.ieee.org)

Article summary

An Indian startup, Agnikul, has successfully launched a rocket featuring a 3D-printed engine, which was fabricated in just 72 hours. The company aims to provide low-cost, on-demand launch services to operators of small satellites. The launch was a technology demonstrator to test out key subsystems necessary for an orbital launch. Agnikul plans to launch its first commercial product, a two-stage rocket called Agnibaan, next year.

What commenters say

• The use of 3D printing in rocketry is not a new concept, and the time it takes to manufacture an engine depends on its size and mass.
• Allowing mass migration of unskilled labor can have negative consequences, such as increased competition for jobs and strain on public resources.
• Immigration policies should prioritize skilled labor, as they are less likely to be impoverished by being unable to move to optimal locations.
• The concept of borders and property rights is arbitrary and has been created by humans, and a more open and borderless world would be beneficial.
• The idea of a borderless world is unrealistic and ignores the complexities of human nature and the need for security and property rights.
• The use of 3D printing in rocketry can enhance a country's military capabilities, particularly in the development of ballistic missiles.
• The Indian space industry has the potential to become a major player in the global market, with companies like Agnikul leading the way.
• The discussion around immigration and labor is closely tied to issues of global inequality and the need for more equitable economic systems.
