Help with complicated print

Recommended Posts

Posted · Help with complicated print

Hello friends,

I am new at 3D printing. I have printed out some simple things but now I want to try something more complicated. I am using Cura to attempt to print this model. Everything looks good in the Layers view. I am using support everywhere, but I have a problem with the feet coming unattached and falling over even with the supports. I have been using the default settings for "normal" quality print on Cura, except I changed the "Brim line amount" value from 20 to 30 and changed the "Overhang angle for support (deg)" from 60 to 45. Can anyone help me to create a gcode file from this .stl that will print correctly on an Ultimaker 2?

WARNING: NOT SAFE FOR WORK, some nudity. The link below is to the .stl file



Any advice would be greatly appreciated.

    Glen I am not familiar with the Cura "simple" settings but I bet the print speed will be too fast for that model. I would suggest you use "high" quality setting or whatever it is called. If you are printing thin stuff, especially if it is leaning, then the answer is slow and cool. So you need to address print speed, extruder temp and fans. In fact if you select "high" quality I would then go into the Cura menus, basic and advanced and set...

    print speed to 20mm/s or 30mm/s, no faster

    layer height to say .15mm

    extruder temp. 195 (I assume you are using PLA)

    And under Cool on the expert settings I would go for it and set

    fan full on height 0.6

    fan speed min 40

    fan speed max 100

    min speed 10

    cool head lift tick

    That is quite aggressive I think, if you have a problem try the fan full on height at 0.75 or 0.9

    Now all of the above is general stuff for that model, it is not directly addressing your question the feet falling off. That confuses me, are the feet not sitting on the print bed?

    thank you friend. I will try your settings and see how it goes. Everything was adhering to the print bed just fine, but the nozzle kept knocking the feet over once they got to a certain height. I didn't try slowing the nozzle down or checking the cool head lift option.

    Thanks again,

    Yup the ankles and shins look thin so I suspect you ended up with filament raised up on the edge, either because it is difficult or through the movement to that spot or retraction and movement away; once you get a bit sticking up it tends to grow. If need be you can manage it with screwdriver with a small thin edge and just push the raised bit down flat after each pass and then it may well clear itself.

    It would be useful when you respond to note down what settings you used and also what your retraction settings are - located under Expert settings

      • 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!
          • Thanks

      • 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.
