Cura not slicing model


Recommended Posts

Posted · Cura not slicing model

We are trying to print some basic item for children tricycles at local school.

The item is a 50mm dia, 15mm high puck shape hollowed out to a depth of 10mm with walls and base 5mm thick.

We have created the stl file in both Fusion 360 and Tinkercad to see if problem was at the design stage.


Our problem we are slicing in Cura 4.13 & Cura 4.7 and all appears well until we print.

What is happening that the printer is not creating the hollowed out part and we have ended up with a solid Puck!!

We have tried 3 different printers and we get the same result.

Any ideas what we can do to just print a very basic object ??

Any help appreciated

    The preview should be showing exactly how it should print.


    Next to the Settings Search box is an icon with 3 lines on it for "Settings Visibility".  Click on it and set it to "All".

    Go down to the Mesh Fixes section and make sure "Remove all Holes" is NOT selected.


    Models created with Fusion 360 are pretty good and rarely have problems.  TinkerCad...not so much.  If there is an open seam at the top of the model ("not watertight") or if a surface is inside-out then you can get errors in the slicing as Cura gets confused by conflicting data in the model.
