Layers split with litte force, due to missing "full layer"

[foxylion 0]

Hi,

I'm facing some issues with my printed model that breaks to easy at a given height where the model changes it dimensions.

 

I've attached a photo of the printed (and destroyed) model, the STL file and a screenshot of the Cura rendering.

I suspect that the bad stability of the printed model is due to a missing layer that connects the two model parts better. It is only connected through the infill of the lower layer.

 

Does anyone have a tip for me how to print the layers below the change in dimensions in such a way that the bond between the two parts of the model is maximal?

 

Best,
Jakob

One way is use the support blocker tool and make the joint 100% infill

I think what is happening is that Cura is calculating based on 2 wall loops, and there is no "Top" or "Bottom" in that area.  If I change it to a single wall, then the top and bottom show up and the upper portion is supported with a regular interface.

 

So yes on using the support blocker to modify that joint with 100% infill (or more walls).

 

Would it be possible to add a chamfer at that joint?  Even a small chamfer is better than none and would cause more plastic to be put in the joint.  You would still need the support blocker though.

Thank you, I didn't know about the support blocker feature. That helped!
