I have an idea for a slightly different approach to 3D Printing.
In conventional 3D printing the printer builds up layer upon layer of
material, constructing the entire solid structure as it goes. But suppose that
instead of constructing it as a solid, the printer builds up layers so that
only the shell of the structure is built. Then, every ten or twenty or
thirty layers it fills in the shell with a liquid, perhaps a two-part
self-curing epoxy or a UV-curable liquid.
I'm thinking that this approach could significantly speed up the overall
process and possibly result in a stronger final product.
Anyone have a 3D printer they'd be willing to hack in order to give this
approach a try? It could be the basis for a new 3D printing technology, maybe
even a new company.
