not sure what the other fellow meant, but when 3D printing first hit the scene, the hype was that we'd all be printing replacement parts for our broken appliances and what not. i'd bet my pants that there have been more Benchys printed than repair/replacement parts for consumer appliances.

It's hard to make parts for things that are designed to be unrepairable.

That said it's also hella not cost effective. I'm in $400 or more, and have only printed a few daily use items. My printed clothes dryer knob has been working great for a few years, and my printed curtain rod brackets are working fine so far this summer. The replacement button I made for my father's CNC lathe is working fine a few years in too. That said, being able to sketch something, bang it out in openscad, and have a part waiting for me on the bed the next morning is pretty magical.

Exactly. "consumer" is the important qualifier. Yes printers are relatively cheap and reliable, but even the most consumer-centric printers are far from "plug and play" last I checked.

When there is a printer that an "average" person can take from new-in-box to reliably printing Benchys in less than 24hours then consumer 3D printing will have arrived. We aren't there now, and I'm not sure when, if ever, we will be.
