/diy/ - Do It Yourself

Not same question but still relevant.

From work i have a contraption to cool air to a temprature ranging -20 and -40 Celcius.
If printing PLA, and keeping my extruder hot enough. will the machine be able to achieve very high feed/print rates?

Or would the PLA just stop melding with the previous layer because its too cold

I also had some ideas about spot cooling the just printed extrusion and keeping the rest of the piece at room temprature by immediately extracting the cold air with a fan and aswell cooling the extruder head with that air.
