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.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
