> We're talking about injecting filament into a well-insulated channel where it's physically impossible for it to receive any active cooling whatsoever.
Look up the thermal conductivity of air.
Then look up the thermal conductivity of 3D printing filaments which form those channels that are being injected into.
The filament will be cooling faster in the channel than in free air.
This cannot work unless the part is heated to a temperature where the filament flows.
