    @v3dprinting given you are seeing the part taper in towards the top, could be that it is warping, rather than a specific part issue? It also sticks out at the top where you have the solid layers (and so are putting in a lot of heat and different cooling?).

    Have you check what the temperatures and cooling fan percentages are between the two slicers? I know PrusaSlicer can display the cooling fan % thought the gcode preview

      warping/shrinkage seems likely.

      When does your layer fan kick in?

      Can you try a print without the fan?

        @engikeneer I 100% sure of my bed adhesion.
        Many years of practice as a 3d printing service provider.

          The part is printed in PLA, so shrinkage is minimal.
          Remember the same part with same material on the same printer printed with S3D with the same main parameters turns out well

            Temperature is even throughout the whole print.
            I need to dig much more into the cooling settings as PS is fiddling with it. That’s a difference with S3D. Maybe the cause.

            Setting the default extrusion width to 0.42 for a 0.4 nozzle didn’t solved the issue.

              It looks like the layers were the issue happens are infill layers were the fan is on. For bottom and top solid layers, nearly no fan.

              With S3D I have a constant 50% fan on starting layer 2 an 15% on first layer.

              PS is making is own fan speed profile from 15 % to 50 % with my current parameters.

              I need to get back to something much simpler and close to S3D first to see if it has an impact.

              I will do the test tomorrow morning, when back in the office.

                  @phaedrux Yes, not as simple as a simple shrinkage.😧
                  I was a bit quick when setting up the cooling options, it's not as straight forward as on S3D or Cura.
                  I will do a new test print with PS with no variable fan cooling : 50% starting on layer 2 and always on.
                  I'll keep you updated 😊

                    @Phaedrux @engikeneer You were on the right track with the shrinkage / cooling setting.

                    I have done a test print with no layer fan on layer 1 and 50% fan on other layers. The result is much better.

                    Thanks for your valuable advices.

                    I still have a small elephant foot on bottom solid infill and first layer is a bit too large (Z offset has been made remotely with DWC with a pitch of 0.05 instead of 0.02 on the panel due) and last layer of the top solid infill also (flow rate still too high for that material for the ironing)

                    The blue material is ColorFabb on Demand and depending on the colors, it can be very tricky.

                    I'm doing another test print using PolyTerra for the main part to confirm.

                      I do confirm that the issue was the cooling settings.
                      The ColorFabb On Demand filament, in that particular color, is prone to create the issue.
                      Polyterra filament does not create any issue with the constant cooling setting as in S3D
