I can't speak to the proximal cause of the roughness and porosity, but if you've ever held a raw printed aluminum part in your hand it is immediately apparent. That said there are processes to deal with porosity like Hot Isostatic

crack growth in metals is driven by microscopic flaws that cause high-intensity but very localized stress concentrations. Over time even low stress levels cause these flaws to grow to the point where they start causing strength problems. Ev

It has mild strength downsides, but very severe fatigue and damage tolerance downsides. Knowing this, it makes sense that 3d printing tech would make headway in space industry but not (yet) in aviation

Just two weeks ago protonmail had a massive outage related to data center cooling failure.

There's a thriving community of aerospace startups in the US right now that are eager to snatch these NASA folks up. It won't be the right move for all of them, and it's unfortunate to get displaced from a comfortable, presti

Progress on airplanes is often tracked by # of engineering drawings released, which means that 1000s of little clips, brackets, fittings, etc. can sometimes misrepresent the amount of engineering work that has taken place compared to prepar

I recently started a new job (big upgrade from my last gig), and after onboarding, one of my interviewers told me that a major factor in him recommending me for hiring is that I "looked bored and ready to move on" during the techn

I work in this space. Most likely it is a huge conglomeration of commercial CFD, FEA, and CAD softwares, custom in-house codes, and empirical aircraft design curves all stitched together with some python.
