During testing, 3D-printed external components absorbed water below a certain depth due to infill porosity, nearly causing the submarine to be lost. The builder managed to recover it and complete limited dives, highlighting the challenges of waterproofing 3D-printed parts for underwater use. ## Full article daily.dev links to this article rather than hosting it.
