How to print surface with zero thickness?


Recommended Posts

Posted · How to print surface with zero thickness?

Hello everyone!

I am trying to print below geometry with Ultimaker 2.


In modeling software(Rhino), the thicknesses of the surfaces are 0 mm and no top and bottom.

Could you please let me know the way to print it with Cura or make GCode for Ultimaker without no thickness in modeling software(Rhino)?

    A surface model has 0 thickness, so it's not actually a solid or closed mesh. You'll have to use the thicken command (that's what inventor calls it, not sure what it's called in Rhino) to apply thickness to the surfaces. This will turn it into a measurable solid. I would start with a thickness of .42mm or greater, depending on how many passes you want the print head to take.

    *Note: The printer will always take at least 2 passes.

    Goto the expert options, in "black magic" there is "only follow mesh surface" this will most likely do what you want.

    This is the limited case where this option is for :-)

    If you want inner walls and not just outer walls you might have to make the walls .81mm thick (not .41) to get Cura to slice it. But the "black magic" feature is worth trying. Make sure you look at the results in slice view before deciding if it worked.

    Thank you for everyone!

    First, I have tried the advice from Daid.

    The way of extruding material, path(red lines in Cura), is exactly what I was looking for. But I met two additional issues with the way .

    1. How to control the thickness of printed shell with using the option of Only follow mesh surface in Black Magic?

    When the shell is printed with option of Only follow mesh surface, one layer is completed with only one extruding path.

    2. Is it impossible to print inside surfaces?

    Inside surfaces cannot be recognized in Layers View Mode and cannot be sliced as below images.


    Second, I have a question with gr5's advice.

    1. Does the inner walls which you mentioned mean the surfaces which cannot be recognized in Cura which was mentioned in my above question?


    >If you want inner walls and not just outer walls you might have to make the walls .81mm thick (not .41) to get Cura to slice it.

    If so,

    I tried to make the walls .81mm. But there is no change in recognizing and slicing the inner walls in Cura.

    Could you please let me know what I have to do in next step?

    Third, I have tried thicken the surface for solid geometry which was advised from Solid Print 3D.

    But at present, I am suspending the way, because there is the part which go wrong when it is thickened.


    Thank you again,

      • 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.
