Should I turn off print cooling?
No, ABS does not need a cooling fan and will likely cause printing failures if turned on due to warping from rapid temperature changes. Fans are best disabled or kept at around 20-30% for ABS 3D prints unless you have an enclosure/heated chamber with a high ambient temperature.
Do you need part cooling for PLA?
Optimize Your Cooling Settings Cooling is one of the most important aspects of printing with PLA. Having a dedicated part cooling fan makes a huge difference in the quality of the printed parts. The freshly extruded plastic needs to cool down below the glass transition temperature as quickly as possible.
Can you cool PLA too much?
PLA: There absolutely could be to much cooling with pla. With the RailCore printers stock fan, pla speeds should be between 15-30% at 60mm/sec. Anything above that causes issues that present similar to pressure advance tuning issues or z axis issues.
Does ABS need cooling?
Print quality with ABS can be surprisingly good since mostly you don’t need part cooling with active fans and such. ABS and ABS-likes will print well if you just grab your PLA profile, turn off the cooling fan and adjust temperatures.
How does minimum layer time affect fan speed?
This controls the fan speed on the initial layer only, which adheres to the build plate. The speed then changes back to the regular fan speed, which is achieved once it reaches the height setting for the regular fan speed. The minimum layer time determines the time it should take to print one layer.
When to leave a cooling fan on and why?
The basic understand (cool the plastic once it’s out of the nozzle so it reaches a solid state faster and doesn’t deform) just argues to “leave the fan on all the time”.
What happens if you print PLA without cooling?
However, cooling is very beneficial for getting sharp lines and corners on models. If you print PLA without cooling you will quite likely get curlig at the corners. This is a process that often makes itself worse,layer by layer, because a corner that has curled up might touch the nozzle on the next layer and get even hotter.
Why do you need a cooling fan for PLA?
The fan is designed to bring it into or just below glass point so that it cannot curl. Some PLA will always need cooling, others can live without it. sometimes making layer times longer can have the same effect to allow plastic to naturally cool.
