Yes - there will always be a little bit of extra filament needed, and therefore a little bit of extra print time required.
I’ve got quite a few ideas for ‘flush into as colour doesn’t matter’ objects - such as
- Large multi part functional items - designed with ‘flush-into’ specifically in mind, that can be built up over time - such as:
A flexible size table - made out of multi colour flush - that I am calling the ‘purge-table’.
Plus other big multi part things like shelving etc. See Making better use of Flush-into object in Bambu Studio - #12 by Ukdavewood - Xmas decorations - such as multi coloured balls etc -
- Printer add ons - like AMS risers / AMS helpers / Scrapers etc
- Storage - like Gridfinity etc.
- Decorative things like Vases and 3DPB string art etc that are actually enhanced by the ‘random’ multi colouring
- Big strong functional things - like the parts for the MPCNC for example
- Custom packaging for fragile designs
- Internal components of decorative items
Ultimately what I would like to see if for users to be able to create Makerworld collections of things they are interested in printing at some point - then for makerworld to have the ability to automatically suggest things out of the collections that are appropriate for multi coloured objects being printed.
Have made a start on a collection here to try and illustrate the sort of thing I am talking about. Flush-into colour doesn't matter | Collection - MakerWorld
