Printing walls as thick as nozzle size/ line width


Recommended Posts

Posted (edited) · Printing walls as thick as nozzle size/ line width

Hi everybody,


I have been doing some research on how to print single-line-walls and saw that other people are struggling with this also, but I could not find any satisfying solution to this issue. This is why I made this post to clearly describe the problem I am having.


The issue sounds simple but seems to be impossible for Cura to solve. I want to print walls with the width of a single line. The object I am using is attached below and is a hollow cube, open on top (a box basically). This means I have a bottom part, in which I chose to use 1 wall and the rest is done using infill (no bottom/top settings were used). After that, I want to build a wall around the circumference. This wall is designed to be 1mm and the nozzle orifice is 1mm as well. Sounds simple, just extrude one time around, but Cura cannot figure that out.




Here is what I tried, and the results it yielded:

  • If Print Thin Walls is not activated, then only the bottom part is sliced, the walls are ignored. Not an option.
  • If Print Thin Walls is activated,  then the whole structure is sliced but the wall part geometry is all messed up (no wall options are used) with weird overlapping corners and some walls are being printed with two lines for no reason at all. See pic on below left.
  • If I make the Wall Line Width slightly smaller than 1mm, nothing changes. If I make it drastically smaller, like 0.85mm, then walls are being sliced as intended. BUT the walls are being printed with two lines and end up much thicker than designed. In my case the wall width was around 1.5mm instead of the desired 1mm. The pic below shows that a wall (red line) already had been produced but the nozzle would make an other round nonetheless before a layer change occurs. See pic below right.
  • Increasing the wall width of the CAD model did not result in a better result either.
  • Changing the settings to a lower nozzle orifice like 0.8mm, and line width, does not solve this issue either.
  • Reducing wall flow does not help either.




It is irritating that on the bottom/infill part a wall is being produced with a width of 1mm, hence in combination with other lines it works. But if only 1 wall shall be produced it bugs out. More concretely, it is not possible to make 1 wall with 1 line and 1 print motion followed by a layer change, even though the nozzle orifice is the same as the wall thickness.

If you know how to fix this issue, please let me know.

Thank You.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
