Ultimaker not slicing correctly

Recommended Posts

Posted (edited) · Ultimaker not slicing correctly

Help please,

After I slice a Print it always turns a part of the print semi invisible when I go to preview




















first I thought it just didn't show it but print it regardless but It just won't print it and I just dont know why


I used a premade file from Thingiverse and cut it in pieces with Meshmixer 

some of the pieces work but most have this problem

    Depending on how you or Meshmixer left the edges they could be open.  If they are then your model is not watertight and won't slice or print correctly.

    You can use the Mesh Tools plugin from the Marketplace to check your models.

    I don't know MeshMixer.  If I need to alter a STL file I use MS 3D Builder which is bundled with Windows 10 (and I think Win11).

    Depending on how you want to change the STL you could also use Cura's Support Blockers.  They can be configured to do different things by changing their Per Model settings.
