Missing parts in 3D Modeling when printing

Posted · Missing parts in 3D Modeling when printing

Hello,

My name is Tidusho. I've just bought a Ultimaker 2 but I had got some problems. This object was created by 3DS Max 2015 and exported to .STL. After reviewing on Cura and saving to .GCode, there are missing parts. I don't know how, please guide me.

    From what I can see, you're model has little to no thickness and that is why it is not printing most of it. Make the shell thicker. Use the shell modifier in max and set it to inwards (obviously)

    Thanks for your support. This is my model which designed in Maya and used to make a short animation. There were some problems when printing. I am worry if I have to re-build whole model for 3d printing.

    modelling for cad, and animation, and games and 3d printing are all very different. Also size matters and shell thinkness is the most important in 3d printing as when you print small your shell tends to become too thin to print. If you make the model solid then you control how thick it is in cura. I did read a slicer that was going to thicken the shell for stuff that is too small, which would be a good feature for people who cant model and want to print random stuff off the web. As most things are not designed to print.

    To make youre model good, just close all the holes on ALL elements and then activate the intersections from the advanced menu in cura that way you dont need to boolean or weld verts and you should still be able to animate it just as before. I use 15.04.2. You should be fine then. I would print the body in one, and the head seperately in two halves for maximum quality, or just experiment for yourself as you might not care about quality like i do. Lol. Good luck.

    I haven't still found any solution for my model yet and now I also get a problem with other model.

    Could you please guide me in setting these files on Cura? I can't print it by ABS without problem :|

    I think I heard somewhere before that 3DS Max has trouble making watertight STL's,

    you might want to run the STL's trough Meshmixer to see what the inspector finds, and maybe adjust the way you draw.

    I honestly dont know why people even export stls files. I never do and have zero issues. Just export an obj. Obj is limited by polycount, but for cad stuff you will always be fine. Its into the millions so dont even worry about it. I use millions of polys frequently and have no problems. I also do almost all my slicing in max or maya and they produce identical results. If your model is not closed then you need to close it. Auto capping does not always work the way you expect.

    And @tidusho, seriously man, dont try to print that in one go, do the legs seperately.

    Also why abs? unless you really need to? but just print with pla. There are no real advantages other than maybe heat for abs so if its going to be outside or something in the sunlight. Some people print with abs for no reason at all.

      • 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.
