Cura won't generate infill or top layer

Posted · Cura won't generate infill or top layer

Hello, I'm new to the forum and relatively new to 3D printing.  I've been prototyping some tools and parts for my company, and came across a problem to which I couldn't find an answer through google or this forum's search:

 

I have an STL generated in solidworks that I've placed into Cura version 3.1 (mostly awesome program BTW), and it refuses to generate the top layer or any infill within the part unless the infill is set to 100%.  It will not even generate support inside the part.  I'm thinking that there is something wrong with the STL, but I am not skilled in investigating model problems.

 

The "Solid View" shows the top surface just fine, but switching to the "Layer View" reveals the problem.

 

I've tried:

 

-Re-modeling the SLDPRT file completely, saving as an stl, then re-importing it into Cura.

-Increasing and decreasing both the wall and top/bottom thickness.

-Enabling and disabling generation of support

-Changing infill percentage from 1 to 99%, but the only time the top surface generates is with this at 100% as I said.

 

Please help?  If I need to upload more photos or files please let me know.

    I see you have infill at 99% yet it's hollow inside.

     

    Is it important to be hollow inside?  Basically you gave the walls a thickness.  Which I hope is what you want.  Probably what you want.  But maybe you didn't also give the ceiling a thickness?

     

    Look at the part in xray view as well.  If you see any red then that's the problem right there.  Or if the ceiling is thinner than .1mm (your layer height) then that would explain the problem.

     

    If you see red then you can fix the model in cad - it has either not enough walls or too many walls.  or that top wall is infinitely thin (and it plans to print it infinitely thin, lol).

     

    Or you could try fixing the model with a free service.  But it sounds like you know CAD so maybe fix it in your cad software.

    Great you fixed it - I was going to say and I still will, for your benefit. I have been using Solidworks to model and create stl files for over 4 years now and have NEVER had a faulty stl file produced. As they say you get what you pay for.

    Please post your project file so we can see what is going on.  In cura do "file" "save project..." and post that file here.  It will contain your model(s) and your machine settings, profile, and your settings overrides.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
