The FAA is likely to say "no." I can't remember what crash it was in the '80s that took us from the glorious future where all the jet setters got off their private helicopters on their skyscraper rooftops (remember Tron? Remember Runaway? Remember how everybody was doing that in the movies in 1983?) to the current mundane "law enforcement, news and life safety only" universe, but it was literally one crash. A 10kg drone simply experiencing a power failure at 500 feet gives you an impact energy equivalent to a hand grenade. There are reasons to use this technology. "You're too lazy to schlep your ass to the Apple Store and too impatient to wait for a fucking truck" is not one of them. If I had to bet on package delivery in 2026, I'd bet on Fedex Home Delivery, only not Fedex. It'll be privateers, organized into a loose fleet, working as independent contractors. 3D printing is nice for prototyping but sucks for manufacturing. The materials strength will never be there and the materials cost is shockingly high. The price will come down but 3D printing technology will never compete. Even if I'm using the exact same polymer, injection molding it gives me a real leg up as far as durability, flexibility and tensile strength over layered deposition. And hey - if I need to work with, you know, metals and wood and composites and glass and Lexan and Plex and pretty much anything other than Cheez Whiz, it's no contest.
