Missing and extra lines


Recommended Posts

Posted · Missing and extra lines

Hi All


I am new to 3D printing and enjoying learning the tricks. Not too many failed prints and have spent a lot of time on Youtube and forums and managed to solve most of my problems but this one has me stumped.

Why can I not slice this right? Model size is 160mm x 64 x 4. I am guessing it is something to do with holes and overlaps and tried some software to repair it but it seems to stall.


Looking for ideas as to what we are doing wrong.

    The model has problems, it's not manifold (aka watertight). Install the Mesh Tools from the marketplace to get these warnings.




    Having said that, it seemed to slice reasonably OK for me...

    Thanks for the reply and confirmed what I thought might be the problem. The design done in 2D then made 3D and had too many overlaps. It is now fixed in the original design and looks great.

    I have the Mesh tools now too.

    Thanks al lot!
