Suggestion Idea for 3-D printer support

Please find my suggestion that I hope will make improvement And Saving time and PVA to make great print?

I suggest that we print a part the required support use full PVA which is not cheap and take times between the two extruder for each layer when the machine printing for saving time and 

support filament, we can print normal with PLA in example but we only add to layers of PVA between to part and the support see drawing see Attachment A1

Yes!  Great idea!

 

Cura has this feature.  It's more complicated than you show as areas that need support aren't always perfectly flat.  But it does save a lot of PVA and for the part you show above it saves a lot of time as well. 

 

In Cura the feature is called... well I don't know what it is called.  This feature was added recently so make sure you have the latest version of Cura.

You can just change which extruder to use for the different areas of the generated support.

Hi Thank you, try it but this is very complicated why is not by default as in one click option I hope they add it

I mean, it's almost one option as it is. Changing "Support extruder" sets all the options below to that extruder (which you'd have to do regardless) and then change "Support infill extruder" to your other extruder and you're done.

 

It's not a super common thing that people ask for since quite often it's not applicable as the support would be stuck inside the model.
