We are struggling to get holes to be accurate dimensionally.  We’ve been printing parts that have a 1.25” hole, but they always seem to come out to roughly 1.23”.  Walter has tried changing the setting in Cura to Inclusive and Exclusive of the line, but I didn’t see any change.  Suggestions?

    Unfortunately, holes are always too small, especially horizontal ones.

    This is because the filament inside the hole can expand more. You have to think of it as a rubber ring that shrinks a bit when it cools down. There are also no usable settings to prevent this, because all settings in Cura that refer to the dimensions would not only change the hole but the whole object. Therefore there are only 2 possibilities, either draw the hole bigger in the CAD design or drill it afterward.

    Hey Barb,

     

    Especially holes are often a problem. There is one setting in Cura where you could make the wall thickness negative.

    Sorry it`s in German. Just go to settings and activate Horizontale Erweiterung. I usually use the scaling factor of 100.19% for my filament  and set the "Horizontale Erweiterung" to -0.05 mm. You should try this and measure your results and maybe adjust them acc. to your filament/parts.

    Horizontal Expansion is for all x & y dimensions, so if you enter here a negative value also the outer dimensions will be reduced not only the holes.
