Hello Guys! 

 

A question i have since some month regarding printing objects so that they fit perfect into each other. In my CAD drawings i draw without space between my separate parts, but then i want to print, i have to adjust around 0.4-0,6mm space between, so that they fit into each other, like on my screenshot. In my mind, there should be a way where I can import the whole model and the slicer program recognizes the individual parts and renders them accordingly, so that I can then print out one part after the other. So far I haven't found such a solution. How are you doing?

Thank you for your answers!

warm regards

Andreas

    The problem is not that Cura thinks that the two models are one, but they "melt together" while printing. Printers are not infinitely precise, like your models can be.

     

    You can adjust the "Horizontal Expansion" setting to have Cura print the models with slightly more room between them, so they don't melt together as much. Also check out and experiment with the "Slicing Tolerance" setting.

    This can be done by tweaking with the horizontal expansion,

    FI on my S5  with PLA i use a horizontal expansion of -0.03 but with ABS its closer to -0.02.

    Best way to test is to make cubes of 10mm precise and tweak the expansion until the print is exact 10mm.

      • 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
