Outer Skin - save your expensive material

[Labern 774]

Hi

I'm not to familiar with dual extruder and how it operates in cura, as i'm waiting for the kit to come out for UM2.

But i was thinking today as i was printing with bronzefill, if there will be a way with dual extruders to be able to print the outer layers with bronzefill and the rest with PLA to save on cost? Is the feature there to be able to do this?

The idea is good... Somewhat...

I guess you could maybe achieve it by making a duplicate of your model, scaling it down slightly, and printing it inside the original, in a cheaper filament?

However, there is more to copperfill than the outside look, you would loose the heavy weight of the print, which I guess (at least to some) is a big part of a copperfill print?

I print at 20% fill, the reason is to add weight to the print. I have minimal 3 outer layers (1.2mm). And I make sure each line in the layer sticks to eachother. So the object outside can be sanded a lot without breaking through the first outer shell line.

@Labern: You should not forget that swapping the extruder also needs time. And you have to properly prime each nozzle after a swap. This also needs some filament.

Sure you can do that but using slic3r as software. There you can define which extruder does infil / perimetres / support material and support interface

Yeah I get the weight thing but I'm printing something to go on the wall and it's just for the looks. Weight is not a factor.

I wasn't just thinking of thinking just for bronzefill. I find woodfill lacking in strength. So the strength could come from the inner and just have a woodfill skin.
