Air fryers are just convection ovens packaged differently.
Sort of, but not really. Air fryers have a much faster rate of airflow than any convection oven, which results in significantly faster and more even cooking. The air fryer really is a meaningful technological development.
I don't know that I'd argue that "consumer" 3D printing, as in a printer at home that just churns out a part when you want it, is even really hear yet, certainly not in the way that a dishwasher or lawnmower is. You need to do your own slicing, thinking through supports and brims and layer height, and the printers themselves need no small amount of troubleshooting that is much more than "turn it on and off again". So…

Microcontrollers and stepper motors were already controlling 2-D printers in the 01970s and early 01980s at higher speeds and similar powers to currently popular 3-D printers. The first RepRaps did not "use a full-power PC as their host machine"; they were controlled by AVRs, just like Arduino (which didn't exist yet). Generating motor control waveforms on a full-power PC is a nightmare nowadays, and was already a ni…
Now I'm very tempted to build a 3D printer with an 8-bit home computer and vintage parts.

An offtopic question: how do you manage to write all the years consistently with 0 at the start (I know why, but how ), when everyone around you uses a different standard. If I decided, IDK, to write "cnow" instead of "know", or "J" instead of "I", I wouldn't be able to do so consistently. Not in a world that massively uses the other word. Or it would take me twice as much time to double-check everything that I have…

A mixture of patent protection, China’s (lack of) precision manufacturing at scale at that time, and software immaturity. LM8UU around 15 years ago when I started my 3D printing journey was upwards of $15 PER PIECE. You need at least 8 for a Mendel or i3 style printer during the reprap boom. Just the bearings alone would have cost you, $100 or so. Then factor in chrome rods, stepper motor, stepper motor drivers (Polo…
I don't think you can underestimate the development of efficient slicing algorithms. It might just have been something that would have happened anyway with other parts of the story in place, but there was a point in time when slicing anything complicated was very painful.
And with waiting 5 hours to print it isn't unreasonable to wait an hour or two for the slicer either.

(I'm sincerely hoping I'm missing something here and am going to look really silly asking this question.)
