It seems as if we are on the cusp of a dramatic change in the hobby. Especially with the changes in FDM print quality.
There are big changes coming, but 3d printing is still a hobby in it's own right - i have a x1c Carbon bambulab printer that 'just works' I can set the quality and didn't need to watch any videos to get it working - but that was $1000. When you can get a 3D printer for $200 and never have to change a setting, and can just take models off ready to play that when things really change. We're kind of in the dot matrix era of paper printing for plastics, and yes you will want to throw your printer out the window sometimes ;-)
3D printing has amazing potential, especially for the types and poses of models you can make but if I have to watch 10 videos to get the settings right I'm spending more time on tech than on wargaming. I was at the first My Mini Factory conference for tabletop 3D print creators a week ago with over 80 creators in the room for the first time ever it was incredible.
