The main links here are youtube links. where they have web pages, I've added that link at the end.
These are roughly in the order I'd suggest checking for 3D printer reviews. As such, they're not in complete preference order: some of these folks do great stuff but very few printer reviews themselves. They're all worth a follow.
- Angus - Maker's Muse - A tough but fair reviewer. Probably my most trusted 3d printer reviewer. homepage
- Naomi Wu - sexycyborg - Maker who lives in Shenzhen, sponsored by local 3D printer company Creality recently but still a tough, critical reviewer. Big ally of open-source and open-source hardware, and big customer advocate - she was giving Creality plenty of feedback from herself and the community, and which is a substantial part of why the Ender 3 is so well-liked: she hounded them till they did things right.
- Joel Telling - 3D printing nerd - A little bit less critical of a reviewer, but still good. mostly useless homepage
- Chuck - CHEP/Filament Friday - Very creality-centric, but since they're a big deal these days, that's reasonable.
- CNC Kitchen - Not many printer reviews, but lots of very technical, methodical testing of 3D printing techniques and materials. homepage
- Tom's 3D - Pretty good general 3D printing channel, sometimes a little under-polished compared to the others here but still lots of useful info. homepage
