The most important 3D printing happens where supply chains don't reach: disaster zones printing water fittings, remote clinics printing equipment parts, communities making what they can't import.
The pattern that works is local machines plus open designs. A printed part is only useful if someone nearby can produce it when needed, which is why open file libraries matter more than donated hardware. Designs shared once get printed a thousand times in places the designer will never see.
It's part of why our own files are open where they can be. A deadeye design we publish is a deadeye anyone with a printer and decent nylon can make, anywhere. That's the quiet power of this technology, and it costs us nothing to participate in it.
