@Zviad_Sulaberidze theorically speaking, you would need powdered plastics, injected @high speeds, then melted to fuse? Kind of cartridge? Steppers have limites spees for this, as brushless would be benefit more @high speed
ot does not have to be high speed. Motor has speed like a regular extruder
It works but I don’t like it. Check out the Zortrax M2000. Proprietary cartridges only and one of the top printers on 3DHubs
If they can make an ecosystem that works really solid, then yes. A lot of what we do is still tinker, tune, calibrate, fix, etc. A company making a quality printer and designing filament to run in that printer perfectly will make money, but there will always be those who will try to buy that printer and then run something else in it, so while it would ‘work’ in the sense that companies would invest in that, I’m not sure in the long run it will continue to be viable.
Even those running $xx,xxx Stratasys machines have issues with filament and printing. We’ve been looking at converting our Prodigy Plus over to normal PLA/ABS and electronics. Stratasys’ filament is quite well made though, tolerances are very exacting.
@Aria_C_Bramanta if you have seen diy filament extruders, there is a “pushing” screw, tha pushes platic pellets to the barrel, which at the end, where there is a nozzle, heats up to the melting temperature of that platic, and molten (or melted?) plastic is pushed out from the nozzle

@Zviad_Sulaberidze I happens to own one (filastruder) so yeah, I know exactly how it works, thanks for pointing it out to me
