Purge tower shapes?

Hi all,

Does anyone know of any slicers or any way the shape of a purge tower can be changed so something useful can be constructed from it?

That is a good question! I’m not too sure, however, I’ll look into it.


Wouldn’t it be cool if you could specify a separate STL that could get built with the purged filament as you go? Like if you don’t care about the colors of a print (because you’re going to paint it anyway) wouldn’t it be amazing if you could avoid the purge tower entirely by virtue of printing something with the discarded filament that you wanted to print anyway? Better than big blocks of nothing that you’re going to chuck out anyway, right?

Actually, that’s a really good idea. Of course that would mean that the secondary object would, layer by layer, have to use more filament that the main object needs purged, but I suppose it could be done.

Not necessarily… you could still have a purge tower when the “purge model” has a layer that is less than what needs to be purged. There could still be some wastage but it would be WAY less than the alternative.
