Posted · Hide walls on top of model

The problem: The external and internal walls go all the way to the top - the "top" layer is just an "insert" between these walls.

 

Q: How can I make the top layer a complete "cap"?

    I guess he doesn’t want the regular walls on the top layers, but I don’t know why there could be an issue with them.

    You can get rid of the extra wall around the top infill (the option is called „Extra skin wall count) but not the walls, or you can switch to concentric infill, then everything looks the same.

    I don't get it either, but it isn't hard to do.  I think.  Maybe.

     

    Let's assume a layer height of 0.2mm.  

    Using a cutting mesh for just the top layer you can set the Wall Line Count = 0 and the Extra Skin Wall Count = 0.  That will cause the top layer skin to go to the edges of the model with no walls.  In the picture below the part is 100 x 100 x 25.  The mesh is 100 x 100 x 0.2 and it's bottom is located at Z = 24.8.  This means no walls (and raggedy edges) around the top of the part.  Changing the Top/Bottom Line Directions to [0,90] helps a bit as seen in the second image.  It will still be messy on 2 sides.

    Bring in a support blocker.  Select the Support Blocker.

    Using the SCALE tool, de-select "Uniform Scaling"

    • Set the X and Y sizes sufficient to cover the area you want to change.
    • Set the Z = {Layer Height} * {number of layers you want to change}.  You only want the top layer, then the Z dimension would be 1 layer thickness.
    • Select the Move tool and move the Support Blocker into position over the model.
    • Select the tool above the Support Blocker tool (it has 4 small shapes on it).
    • Select "Modify Settings for Overlaps".
    • Select "Infill Mesh Only" and change it to "Cutting Mesh"
    • Select "Select Settings" and under Shell select Wall Line Count and Extra Skin Wall Count.  Close the dialog.
    • Set the Wall Line Count to 1.
    • Set the Extra Skin Wall Count to 0.
    • Move what was a Support Blocker and is now a Cutting Mesh into the correct Z position so the top of the mesh is the same as the top of the model.

    Here is a block with a single wall for the top 4 layers.  If you select the "Eraser" you can change the Wall Line Count to 0 and there will be no walls for the top 4 layers.
