Posted · Touchingpoint of triangles not generated

Hello,
In my design I have the Mitsubishi Logo integrated which has the central "meeting" point of the lines.
After Slicing, this point is strangly not generated. Is there a special setting that has to be activated for this kind of structures or can this only tweaked to work with changing some values?

Thanks for the attention 😀

    It's just the nature of FDM printing.  What is likely happening is that the points are coming to "knife edges" and once the width of the knife edge falls below the "minimum line width", Cura knows the nozzle can't extrude it and so it is ignored.  The problem with knife edges is that the necessary line width approaches 0.0000 and the smaller the included angle the more model gets excluded.

    You could make an adjustment to the model to ensure that the "point" is at least a nozzle width across.

     

    Just for a test, make your line width 0.10 and you should see the points get closer together.  Make the line width 1.0 and you should see the gap get bigger.

    None of the triangles actually complete.  The narrow one is only 0.8 at the base so a lot of it just won't slice because it gets too narrow.  This is with a 0.40 line width.

    This is with a 1.0 line width and nozzle.  The narrow triangle disappears.
