Abstract: The present disclosure provides three-dimensional (3D) printing systems, apparatuses, software, and methods for the production of at least one requested 3D object. The 3D printer includes a material conveyance system, filtering system, and unpacking station. The material conveyance system may comprise transporting pre-transformed (e.g., powder) material against gravity, by directional conveyance (e.g., of a bounceable platform), and prolonged uninterrupted sieving while minimizing sieve blinding. The 3D printing described herein comprises facilitating non-interrupted (e.g., curbs interruptions of) material dispensing through a component of the 3D printer, such as a layer dispenser.
