Printing Internal CAD structures

Recommended Posts

Posted · Printing Internal CAD structures

Hi, I am designing custom internal structures in my CAD models, but Cura seems to ignore internal voids in my CAD models and just prints solids instead. For example, one of my models is a brick with 5000 pores throughout it resembling a foam. Cura/UM3 just prints the bubbles that break through the outside wall but neglects the fully enclosed bubbles. I need to make custom internal structures for engineering lightweight objects with optimized strength and the supports and infills are too random and arbitrarily designed for what I need. Is there a setting that I have to change to recognize internal structure in CAD models? The only thing I can think of is trying to programme my own infill structure, but this is not ideal and won't work for other conceivable objects that have complex internal structures.

Check out the X-ray view. In all likelyhood you will see (parts of) the internal structure in red, or other red parts. That means your model is "non-manifold" and/or not watertight, so Cura has to make assumptions about the geometry to print.

What you could try is searching for the setting "Union overlapping volumes" in the Custom sidebar, and turning that setting off.
