Abstract: The present disclosure provides three-dimensional (3D) printing systems, apparatuses, methods and non-transitory computer readable media for the production of at least one desired 3D object. The 3D printer described herein comprises, inter alia, an opening that comprises a first side and a second side. A component of the 3D printing, such as a layer dispenser, may be conveyed from the first side of the opening to the second side of the opening (e.g., and vice versa) during the 3D printing. The opening may be closable. A closure of the opening may seclude the component during at least a portion of the 3D printing. Additional features relating to components of the 3D printing systems are described herein.

Abstract: The present disclosure provides three dimensional (3D) printing processes, apparatuses, software, and systems for the production of a 3D object. These may reduce deformation (e.g., warping or bending) in the printed 3D object, as well as facilitate the formation of nested 3D objects. The reduction of deformation may comprise open loop control and/or deviation form a model of the 3D object to generate the 3D object.

Abstract: Provided herein are systems, apparatuses and methods for monitoring a three-dimensional printing process. The three-dimensional printing process can be monitored in-situ and/or in real time. Monitoring of the three-dimensional printing process can be non-invasive. A computer control system can be coupled to one or more detectors and signal processing units to adjust the generation of a three-dimensional object that is formed by the three-dimensional printing.
