3D Printer not printing properly


Recommended Posts

Posted · 3D Printer not printing properly


I'm very new to 3D printing. A couple of things I've tried have worked but the last print keeps failing.


I'm using Sketchup to design then importing into Cura and printing. If there are better ways I'm open to any help.


Whats happening is its printing the rectangular outline up to approx 2mm but then it's trying to print in the air which is obviously impossible. I've tried adjusting the infill settings to full but still nothing.


I'll attach the Cura file.


Any help would be massively appreciated.


Thanks in advance

    You mean "pay particular attention to faces that are light-blueish versus white/grey". Right?

    Thank you so much for such quick answers. I've been looking at it agin and so sorry but I'm still struggling.


    I've attached the Sketchup file.


    If you could advise any flaws if you see it I'd massively appreciate it.


    When I did check if the model is solid it did come up as Group which I guess is the problem I just can't work out how to fix it.


    Thanks again

    Sigh... First of all: Sketchup is not well suited as a modeler for 3D printing. You should really consider a different modeling program...


    If you want to stick with it: start with removing all superfluous inner faces, here are just a few:

    There should be an "outer shell" tool that can be helpful

    SketchUp is not suitable for 3D-printing: it does not produce "solid" models, but a sort of "empty cardboard models" with gaps in the seams. Like paper models you glue together. SketchUp was only ment for visual representations of buildings, not for 3D-printing. It will drive you nuts, and you will waste huge amounts of time.


    I would recommend you switch to another free program, such as DesignSpark Mechanical (for geometric models), or Fusion360. Or even Blender, if you need organic models, although Blender has a very high learning curve.


    There are lots of good demos and manuals in Youtube. Watch a couple and see which interface and workflow appeals to you, and try that. It will cost you some time to learn, but you will soon earn that back.

    Thank you all so much for your replies. I will give Design Spark a go as mine will generally be geometric.


    Really do appreciate your help

      • 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.
