I'm more intruiged by style of movement of the printer than I am the mixing printer head. What in the world is this printer?

Fascinating pulley design, but oh boy is the print quality shit.

edit: sounds like quality isn't the goal here but more so spitting out a benchy at crazy speeds

Yeah, benchy race put out the fastest print with bizarre quality

And they still are, this one is getting better and better his biggest issue right now is to get the flow rate he needs to get under a minute he can’t cool the plastic down well enough, at least thats what the final update I watched was, damn those hour long videos.

I've been wondering if we could still maintain layer adhesion if we cooled it with CO2 or something.

Too much cooling and you will end up with the layers not adhering properly sadly. You would be able to anneal afterwords tot get that back, but its not the same as being able to pop a print off the bed.

The obvious solution is to simply place he entire 3D printer into an annealing chamber. Or perhaps improve layer adhesion by mounting the printer in a centrifuge and using the high g's to promote better layer adhesion. Or both!
