Topic: PLA Dual heater ?
Question to a PROFESSIONAL extruder that has done it all.
Would adding another heater with its own temperature setting closer toward the hopper help with PLA extrusion rate ?
It will effect the amount of per-melted (colder then next heater) before it gets toward the end thus (in theory) help to push PLA out by giving more pushy material pushing from behind.
Rather then having pellets to push what ever is at the nozzle, i suspect that more mushy material in the barrel=more push.
Insulating entire barrel ? Did that already but not sure if there was any effect on that.
Also generally speaking, how long does it take to see the effect on extruded material when changing temperature ? I ask because changing the nozzle temp not changing the temp inside nor effecting the pre-melt amount.
Thanks !
