Cura model rendering broken


Recommended Posts

Posted (edited) · Cura model rendering broken



I've been using Cura for several years and been pleased with the performance. But a few month's ago, the visual rendering of the model in the prepare and preview tabs of Cura has not been working quite right. In the prepare tab, the model features can only be seen when light is reflecting off of them at the right angle. In the preview screen, it's like the print lines are too thin, allowing the infill to be seen through the top layers from the right angle, and severely distorting the view when zoomed in, for all layers except the top. 


I forget if this issue occurred after a GPU driver update or Cura update. I can tell that Cura is using the GPU to render the model because task manager shows the GPU usage increasing when I rotate my view. 


I've had this issue on Cura 4.12.1 and now Cura 5.0 beta.

I'm running a desktop on Windows 11 with a Ryzen 5900X CPU and RTX 3070 GPU


Any help in solving these issues would be much appreciated

    The first two screenshots look like you may be using a dark-gray material. Have you tried selecting a different color material?


    For the preview tab, it looks like you are in "compatibility mode". Either the "Force layer view in compatibility mode" in the General preferences in Cura got checked, or your GPU driver is denying Cura an OpenGL 4.1 context.

      • 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.
