We need to know how you have set Cura up to slice.

After loading the model and adjusting the settings in Cura the way you want - select "File | Save Project" and post the 3mf file here.

What printer?

What version of Cura?

    Part of this is probably a cooling issue.  The Minimum Layer Time and Minimum Speed are coming into play and even at 10 seconds Minimum Layer Time the new layer going down can squish the layer below which hasn't cooled sufficiently.

     

    In the Cooling section of Cura are Minimum Layer Time, Minimum Speed, and Lift Head.  You could try increasing the Minimum Layer Time.  A side effect is that Minimum Speed becomes a problem as going below 10mm/sec can be a problem for the extruder as it struggles to deliver such a small flow rate.  I think Lift Head might create some stringiness.

     

    If you were to print 3 of those at once then each individual piece would have time to solidify before the nozzle comes back to it.

     

    Another thing you can try is lowering the flow for the single wall portion of the print.  At Layer 35 in the Gcode add a line M221 S70 to lower the flow to 70%.  (You would need to add an M221 S100 at the very end of the gcode where the hot end and bed are being shut down to reset the flow rate).

    Single walls mean that the molten plastic is unconfined on both sides.  Instead of printing a rectangle, the plastic is oozing into an oblong shape and the rounded sides are producing a dimensional discrepancy.

     

    And finally - the Arachne beta 2 version of Cura will do a better job on this model.

     

    My results for the wall thickness on the single wall portion were:

    Using Arachne .43 to .45

    4.12 with flow at 66% (.4/.6) ~ .35 to .38

    4.12 printing two parts at once ~ .53 to .55

    4.12 normal printing ~ .63 to .67

    The double wall portion showed equivalent results.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
