Desperate for Advice with Supports


Recommended Posts

Posted · Desperate for Advice with Supports

Hi, I'm desperate for some advice with this print. I have over 20 failed attempts and have tried everything I know. I'm still fairly new to 3d printing, so I'm figuring it all out as I go but this one has me stumped. I have used tree supports but they don't support the bottom of the handle so it doesn't print. The regular supports snap under the handle and pin.  I reached out to the creator of the file 2 weeks ago with no response and I don't know who else to ask. I would love any advice you could give me! Thank you in advance! 😄

    Hi @a4x4girl,

     

    Welcome in here.

     

    I would say, -to be able to help you, we'll need you to save your model as a project file.

    Go to file menu and select save project.. Then share this file with us, -we'll see your object and your printer with the setting you're using in the Cura version used.  This is only possible with the project file.

     

    This is really the best way anyone in here can help with your problem.

     

    Here is a lot of people, and sure someone with the printer you're using.

     

    Good luck.

    Thank you so much for this! I did try a tree support but for some reason, the bottom of the handle would not start printing and was just a pile of strings. Can I ask what settings you recommend for the tree supports. The file does not have any when I pull into Cura.

    Hi @a4x4girl,

     

    I'll see you have a Creality Ender 3 variant of 3D printer, so I'll think we call for @GregValiant he is the one can answer anything about this printer.

    Hello to all.

    I opened the 3mf file that @Carbon posted and that model has errors.  I repaired it with MS 3D Builder.

    The posted model is on the left and the repaired model on the right.  Cura shows the internal errors highlighted in white.

    (I ALWAYS check models for errors before putting more time into a project.

    Here is the slice.  You can see that the bottom of the lever is supported and there is a support interface to hold it up.

    There are about 73 support settings.  Most are general settings.  In this next screenshot you can see that the pull-pin is supported on the bottom edge.  There is also a support that grows to support the pull-ring when it comes back together further above.

    I would make a couple of changes to the settings here, but they would be personal preference rather than something being "off" with the current settings.

    I like a denser Interface when a print starts with a very small patch on top of support.

    With 2 walls and lightning support, this model will be very weak and the leaves of the pineapple may fail do to a lack of base material.  The errors in the model are right there at the base of the leaves as well.  That isn't good.

     

    I've printed models like this and the "lever" of the grenade will be very weak and a failure point if someone just picks it up to look at it and squeezes it even a little bit.  I'd go with Grid infill at about 10% density.

      • 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.
