"Mold" Special Mode not respecting "Support" parameters


Recommended Posts

Posted · "Mold" Special Mode not respecting "Support" parameters

When using the "Mold" special mode, modifications to Support parameters are not respected in the slice.  The slice preview still shows a Support being generated at the bottom of the print, but it reverts from a modified dense zig zag to a very sparse grid when "Mold" special mode is enabled.


I might assume the "Mold" special mode has hard coded support parameters? Is this intended?


More info: 

  • "Spiralize Outer Contour" is required for our workflow
  • We modify the Support parameters to remove the gap between support and print
  • We modify the Support parameters to make it solid at the base (lowest inch of the print) by setting the distance between zig zag supports to zero
  • These modified Support parameters and Spiralize Outer Contour work well together when Mold is not enabled
  • We then enable the "Mold" special mode to translate the printed spiralized single wall to just outside the part
  • "Minimal mold width" is set to the line thickness plus 20% to keep it a single wall count
  • "Mold roof height" is set to 0, this opens the top of the mold and allows us to pour in media
  • "Mold Angle" is set to 90 degrees to trace the contour of the part
  • Problem: the modified solid support structure then reverts to a sparse grid

    Could you please post a project file?  A project file will include your STL (feel free to use an example one if yours is proprietary).  Include it such that we only have to check or uncheck Mold (and reslice) to see the difference.


    Project files contain your model(s) position and scale of model, printer (machine) settings, profile, profile changes.


    To get the project file do menu "file" "save project"

    Please see the attached project file.


    • Look around layer 10 to see the issue. The only parameter you need to change is checking/unchecking "Mold"
    • Slicing with Mold CHECKED creates the desired fully dense support with no Z distance between the support and part/raft.
    • Slicing with Mold UNCHECKED reverts to a sparse support with a visible Z distance between support and part/raft.


    Thank you.

    You need to go back to square one with a set of vanilla slice settings and then change one at a time.  There are some conflicts in your settings and I'm not sure which one is causing the problem.  I think what you are trying to do is get rid of the Z seam for your mold?

    I played around a bit and came up with the attached file.  The bottom of the mold has a hole that I wasn't able to get rid of.

    This is layer 6 and is the first layer of the mold.
