    There are an amazing number of errors in that model.  At almost every interface between the various parts, there is no connection.  Even within some parts the pieces do not actually connect.  You will need to go back to SolidWorks and properly merge all the pieces into a single solid.  I would suggest that all the pieces be solid - no pipes.  Just solid rods and sub-details.

    In the Cura X-ray view the problem areas are apparent.

    That is why it slices so poorly.  You can see the dis-connects throughout the model.  The near pipe only slices the top half.  That infers that some surfaces are flipped the wrong way.

    When designing scale models you must keep in mind that detail will be lost.  When designing scale models for FDM more detail is lost as the printer isn't scaling smaller.  There is a point at which a detail disappears from the preview screen because the printer is physically incapable of printing it.

    I mention all of that because a primary design constraint must always be the fact that the part will be FDM printed and the printers are good, but they don't scale downward beyond going to a smaller nozzle.  Keep it simple and your success rate will be high.

      • 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
