摘要： The present disclosure provides three-dimensional (3D) printing systems, apparatuses, methods and non-transitory computer readable media for the production of at least one requested 3D object. The 3D printer described herein facilitates operation of a layer dispensing mechanism with high precision albeit operating in an enclosure contaminated by debris, e.g., during the 3D printing. The debris may be a byproduct of the 3D printing.

摘要： 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/or an unpacking station. The material conveyance system may transport pre-transformed material (e.g., powder) against gravity. The 3D printing described herein facilitated reducing interruptions of (e.g., providing non interrupted) (ii) material recycling, and/or (i) material dispensing through a component of the 3D printer such as a layer dispenser. The material conveyance system may operate above ambient pressure, e.g., while performing a suction operation. The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for controlling and/or treating gas and gas borne debris in an atmosphere of a 3D printer.

摘要： 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.

摘要： Provided herein are three-dimensional (3D) printing processes, apparatuses, software, devices, and systems for the production of at least one 3D object printed in a printing cycle, e.g., a 3D printer. The 3D printer describe herein may facilitate safe and accurate printing of 3D objects, e.g., when generated from reactive starting materials. The 3D printer (e.g., comprising a processing chamber, or a build module) may retain a requested (e.g., inert) atmosphere around the material bed and/or 3D object during the printing, e.g., at several 3D printing cycles. The 3D printer may comprise one or more build modules that may have a controller separate from the controller of that of the processing chamber. The 3D printer may comprises a platform that may be automatically constructed. The 3D printing may occur over a long time (e.g., many layers and/or one or more print cycles) without operator intervention and/or down time.
