Cura + Soluble Support only on contacting surfaces?

Posted · Cura + Soluble Support only on contacting surfaces?

Hi!

I'm working on a dual extruder setup to use water soluble supports. But this filament is quite expensive and I'm wondering wether it is possible to print just the contacting surfaces with it. Instead of printing the whole support structure water soluble, it would need only a portion to create easy removable support. The main part of the structures would be printed with the primary material, then. Does Cura support this kind of feature? I couldn't take a look at the dual extrusion settings, yet.

 

It would look like that:

'=' is the model with primary filament

'-' is the soluble filament

'|' is the support structure with primary filament

Thanks in advance,

    The "contacting surfaces" as you name them are called "support interfaces" in Cura. In the advanced settings, you can set the "Support Extruder" to your main extruder, check the "Enable Support Interfaces" setting and then set the "Support Interface Extruder" to your secondary extruder.

      • 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
