For media coverage, does injection molding have flashy new use cases etc? My (non-expert) impression is that injection molding is the "boring default" for many use cases, and thus improvement in it won't see much coverage. (+ the specific submission is on a website specializing on 3D printing as a topic). If you show me an industrially made part and say "they injection molded that", the reaction is "sure, as you would", not "Oh? that's interesting, why did they do that?".
Similar to how news will rather report on unusual building materials rather than run stories to remind people that bricks are cool too. (and if a home buyer insists on using something fancy new over bricks or whatever default would be more appropriate, that's their fault)
That's not to say that defaults actually are boring if you deal with them directly, I find people explaining details of things like injection molding fascinating, but "we improved X in a standard industry process" just isn't as easy to make briefly interesting to mass audience and thus gets reported less.
