Nope, 3D printed caps are novelty caps, they are not artisan caps. Artisan, by definition, is handmade. Modeling and printing, while requiring skill, is not artisan.
So my Fetts I make through 3D printing masters and molding them are not artisans?
It's a hazy definition. Your Fett caps can be added to the Directory based on that process. Otherwise a lot of caps would be excluded (eg, at least the GirlDC caps, BBV2, Bro Gamer Sets, HKP, and HiddenPower). All of those were made with a master that was either originally 3D printed or machined from a CAD design.
Even though the line is hazy, it needs to be drawn somewhere for the Directory to be actually usable. Including just any 3D printed cap (eg, Tasker) would make those makers' sections extremely long.
Maybe we should break up the Directory into multiple sections based on different production processes, but that would get confusing for makers that use multiple production processes.
