I'm starting work on a very large 3d printer that uses very large filament. The idea is to house the entire thing in a shipping container and print things as large as cars.
Filament will be some type of epoxy that is to be extruded out of a large 25mm nozzle. A second smaller nozzle using the same material will be used to do finer edges. A third nozzle will be used to produce supports of a different material.
I know this is quite different than most 3d printing applications. I am wondering what slicers I should look into using that are adaptable enough to work with these constraints, or if such software exists.
