Like a "Elephant Foot" problem


I'm facing problem with corrupted shape of the prints. All prints has added "like Elephant foot" material even that it's on supports. Always at the beginning of the prints. Default print profile, 0,05mm and Prusament Resin.

Pls. see picture and let me know any idea why it's happened. Shape should be rounded / oval.

TX & regards

RE: Like a "Elephant Foot" problem

I have a similar issue that makes printing geometric objects nearly impossible. Every print is slightly bent in the direction of the tilting mechanism (looks actually like yours). I think that has to do either with the lifting mechanism, or by the weight of the model. One solution seems to be having a "wall" of very thick supports (e.g. 2-3mm) centered on the side of the overhang (on your picture the right side), that supports the model till the top end.

Is the "elephant foot" defect occuring at the X mark in the figure below? Then I observe the same defect. To check if it is related to the tilting; has anyone printed a similar part on a resin printer without a tilting vat?

yes, the bottom part is the problem. Or better say ... biggest 🙂

Regular shapes that you can't print without support is problematic. Even basic rectangle 1mm thick is finally not right-angled. Problem with assembling parts..

No idea how to tune it.

Looks like a suction problem, as it's happening at the end of the print. Do you have a drain hole in the model?

RE: Like a "Elephant Foot" problem

I used to get this problem, but was able to fix it. Turned out it was due to the hex screw on the print bed not being tight enough. This is the hex screw that you tighten during calibration.

The Fix: Notice that the hex key you use to tighten the hex screw is in the shape of a L, with a long side and a short side. Ensure you insert the short side into the hex screw so that you can use the extra leverage of the long side to tighten it even more. This stops the print bed from shifting during printing

As an aside, I print most of my prints directly on the print bed without supports. It is faster, uses less resin and gives a better result because the print ends up with  a flat surface rather than lots of bumps where the supports snap off. Additionally, some of my prints fail when using supports, but are successful when printed directly on the print bed.
