Posted · i need help with supports

Hello, I am quite new to 3d printing. I mean I have used UP Studio before to 3D print but not to the extent that I needed to use support structures before as much as this one. The project I am doing is on a turbine and I am printing the blades. I split the blade into two parts using slic3r and tried to check how many grams I need of my filament to print one complete set of 3 blades. I placed the half-blade into a Creality Ender 3 Pro and sliced it. But there were no support structures? That does not make any sense to me because the blade is overhanging and when I check the preview, there weren't any sort of support. When I changed the support structure to tree then it properly shows it. I don't really know how to make any sense out of this, hope there is someone that can help me out on how to efficiently 3D print this half-blade.test.3mftest.3mftest.3mftest.3mftest.3mftest.3mf

    You might need to tweak the overhang angle setting. Looks like you've put it at 51 which might simply be too low for it to add support. Not sure why the tree supports show up, I rarely use those. But try increasing the angle value a bit and slice again, they should eventually appear for normal support as well.



    Of course I meant lowering the overhang angle setting. I downloaded your model and lowered it from 51 to 40 and it added supports just fine.

      • 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.
