This is borderline flag-worthy material (the post). Two main things missing:

- What other commenters have pointed out already: Post processing time for the 3D printed parts (as an aside: the quality of a 3D printed would never match that of an injection molded part).

- That the injection mold's mold in an ideal setup for such a small part would have multiple units per mold, thus with each injection one could produce 10+ parts of this small part shown in the video.

Obviously, 3D printing has its own advantages over injection molding as well. But for mass production of highly-repeatable parts (eg: not highly-customizable ("made to order") items such as dental related, or shoe insole related, for which 3D printing works well in mass production), plastic injection molding beats 3D printing hands down.
