My non-technical neighbors have 3D printers, so I think it is definitely heading mainstream. Maybe not for the older generation, but definitely for young people. And outfits like Bambu Labs are pushing it even farther that way. Automatic everything, pick models from your phone, just insert the filament into a hole and you're done. The real obstacle is the difficulty making your own models, but many people go quite a while before hitting that limit; you can get models for a lot of common everyday things without having to design it yourself.
