Abstract:
Systems, methods, components, and materials are disclosed for stereolithographic fabrication of three-dimensional, dense objects. A resin including a first binder, a second binder, and dispersed particles can be exposed an activation light source to cure at least one of the binders in a layer-by-layer process to form a green object including the first binder, the second binder, and the particles. A dense object, such as a metal object, a ceramic object, or a combination thereof, can be formed from the green object by thermally processing the particles and removing the first binder through a primary debinding process, removing the second binder through a secondary debinding process different from the primary debinding process.
