I wouldn't jump to praise so quickly. Additive manufacturing (aka 3D printing) is standard in the industry and the time is dependent on the size (and to some extent the mass) of the engine.
They then further claim you don't need to do any post-manufacturing qualifications, which is absolute nonsense. So it's either misreporting or it's an indication of Indian incompetence/lying.
I don't remember Elon ever stating something does something it's not actually doing. His future timelines are off but it's never his competence that's been a problem with anything relating to SpaceX. And calling SpaceX (the entire industry leader) anywhere near "incompetent" beggars belief.
WDon't believe everything you read in headlines written by people with no understanding of the space industry. If you want to read about the industry, read about it on industry specific sites (like spacenews.com) or from industry specific reporters (Eric Berger or Stephen Clark at ArsTechnica). Davenport at Washington Post is good too.
