Hi everyone,
my round holes and outer diameters are consistently too small after printing with my new H2D.
Round holes - are about 0.23 mm too small
Outer circular contours - are about 0.14 mm too small
I tried enabling “Automatic Hole & Contour Compensation”, but then nothing seems to match the intended dimensions anymore.
The best results I get are with:
X-Y-Hole-Compensation = 0
X-Y-Contour-Compensation = 0.05
But even with these settings, the round features are still undersized.
Has anyone experienced similar issues or knows how to properly adjust the compensation settings to fix this?
Thanks in advance!
Hello
So the nozzle will go around the outline of the hole exactly as specified by the model, but the nozzle does not have zero width, resulting in the hole being too small.
As you have seen, this can be adjusted with the XY compensation.
A further problem is that the slicer often can’t work out what is supposed to be a hole, especially if it’s irregularly shaped, and the further, the filament shrinks as it cools.
While you can tinker with the compensation and maybe get it sorted, the best thing to do is “DFM” (design for manufacturing). In this you design the part for 3d printing, which means making holes slightly wider and pins slightly tighter.
Carbon fibre filaments have a lot more dimensional stability and shrink less.
