Cura Slicing Internal Surface Within Object


Recommended Posts

Posted · Cura Slicing Internal Surface Within Object

I'm using Cura v4.10.0 and trying to print this chain link but they have these divides within the links.


File link: spiral_chain_30_links_0.5m.stl : https://www.thingiverse.com/thing:4870061


It's not the z-seam as changing the location to random does nothing other than move the seams and the hexagons do not seem to correspond to their location.

I did notice that if I look at the model before I slice it, they are these hexagonal faces. The stl preview is able to correctly render the shape but the slicer tries to print it.

Is this a bug and is there any way to workaround it?



Stl view seems to be correctly rendered


You can see the internal hexagons that were maybe used to create the original chain shapes?


The slicer then divides each chain where the hexagon was instead of just printing the solid object.

    netfabb free repair service is here (you have to create a free account first):


    Here's another service - drag and drop mesh repair service:


    Some people recommend tinkercad - it's free - you import your stl into tinkercad and then export it to a new stl and tinkercad will fix many issues.

    By the way - that hexagon is infinitely thin so it should print fine - it will have a line at the hexagon but it should print fine as the shells (red lines above) are touching and will melt together.
