3D printing is an awesome technology. It does produce excellent results and much lighter props than those resin cast. This is the DL-44 ESB Han Solo varian, this is much better than resin counterparts, way lighter and easier to build. Downside is the filament lines, they require so much sanding to be smoothed out, I simply cannot be bothered and will paint it as is. Hopefully the future development will make this part less tidious.
