Cooling small areas


Recommended Posts

Posted · Cooling small areas

I am printing this part and the small section by the hole is having poor quality due to not having enough cooling.  I am looking for a way in the setting to slow it down right here.  The minimum layer time isnt working due to the whole layer taking longer than the minimum time, but these little pillars print fast enough that they just dont come out as well as the rest of the print.

    Add a support blocker on each side.  Size and arrange them to cover just the pillars.

    Select the Per Model Settings tool and then Modify Settings for Overlaps.

    Using Select Settings choose Print Speed and set it to what you think will work.  If will affect everything within the overlapped volume so watch the size and placement.  Two small blocks is probably better than than a large one that goes all the way across and picks up both pillars.

    Varying speeds mean varying nozzle pressure and extrusions.  It's generally not a great idea as it can have adverse effects on some models.
