I will say for ABS this can be mitigated with the following:
An enclosure (I use a comgrow grow tent)
Not opening the printer enclosure for at least 20 minutes (so the airborne particulates settle down)
A replaceable carbon filter (I built a Nevermore duo and bought some activated Charcoal to refill it with)
After doing the above I don’t smell fumes at all. In fact I run the Nevermore even with PLA just to capture any micro particles since the charcoal is easy enough to replace.
Even so, as cool as Resin looks, I’m not having that stuff inside my house with my family. If I did it would have to be in a garage that’s vented but I have a carport and there’s no way I can regulate the environment (temp, humidity) for decent prints. So for now I’m just going with FDM
Basically and then that only makes sense if the company’s going to foot the bill. Otherwise they could just make it very very clear that by using extended mode they’re reducing the lifetime of the battery and doing so at their own risk, yadda yadda.
If it’s, as the article suggests, to use what’s already there (larger capacity) then nah. That’s slimy just like BMW.
Right. Fingerprint is something you are. Can’t be changed. Same for any biometric.
Useful as one part of a multiple factor authentication scheme at best but never on its own. Not to mention there are cases in the US where you can be compelled, forcibly if needed, to unlock a phone. But compelling you to “say” what your password may be covered under fifth amendment protections.
Extrusion is a mix of temperature, feed rate, speed and pressure.
Basically the hotend temp could be high enough that the plastic melts but it still “pushes” just fast enough to build pressure to drive it. Not too much, otherwise the filament grinds and extruder skips, but at the right amount you can keep up with the feed.
The nozzle, lifted up a bit, moves slow enough that the filament comes out and spreads out from the pressure pushing on it. Making the line wide and tall.
The dance is keeping those in sync. Move too fast and the lines are thin, too slow and they’re too wide.
Nozzle too high and it doesn’t blend into the layer below as much as sit on top. Too low and the extra pressure pushes the filament around and it curls back up onto the nozzle.
