Welded rings are the strongest by far, next would be riveted rings. Both of those options require equipment to join the rings and then heat treatment afterwards.

The aluminum alloys TRL uses will begin to lose strength at approx. 350F or 175C. Direct exposure to a candle flame is at least 800C so it would anneal the metal making the rings very soft and weak. H ...

That seems unlikely, 3D printing is still not an efficient process compared to traditional manufacturing. There are also serious design limitations with green sintered parts and the final product is n ...
