A three-dimensional printing system and equipment assembly for the manufacture of three-dimensionally printed articles is provided. The equipment assembly includes a three-dimensional printing build system, an optional liquid removal system and an optional harvester system. The build system includes a conveyor, plural build modules and at least one build station having a powder-layering system and a printing system. The equipment assembly can be used to manufacture pharmaceutical, medical, and non-pharmaceutical / non-medical objects. It can be used to prepare single or multiple articles.

A build plate for a three-dimensional printer includes: a rigid, optically transparent, gas-impermeable planar base having an upper surface and a lower surface; and a flexible, optically transparent, gas-permeable sheet having an upper and lower surface, the sheet upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned on the base upper surface. The build plate includes a gas flow enhancing feature configured to increase gas flow to the build surface.

The invention discloses a multi-material multi-scale 3D (3-dimensional) printing device provided with a single spray nozzle as well as a working method of the 3D printing device. The 3D printing device comprises a base, a work table, a bearing table, a substrate, a power supply, the spray nozzle and a bracket, wherein the base is mounted at the bottommost part, the bracket and the work table are mounted above the base, the spray nozzle is mounted on the bracket, the bearing table is fixed on the work table, and the substrate is fixed above the bearing table; an anode and a cathode of the power supply are connected with a nozzle body of the spray nozzle and the bearing table respectively; relative motion between the spray nozzle and the substrate in x, y and z directions is realized by the aid of relative motion between the work table and the bracket. The spray nozzle is provided with a plurality of feed openings connected with different trace feeding pumps, multiple materials are thoroughly mixed under the action of a stirrer after entering the spray nozzle, and multi-material printing is realized. The macroscopic geometrical shape as well as microstructures in an object and on the surface of the object is controlled reasonably, and multi-scale structural integrated manufacture is realized.

There is provided a support structure for use with 3D printing of objects from computer-aided designs. The support structures include fine points that contact the down-facing surfaces of the 3D object being printed in order to adequately support the 3D object while also being adapted for easy removal after the 3D print process is complete. The fine points are possible by controlling the operation of the dispenser to provide a precise amount of material in a precise location. The dispenser jumps from a first fine point to a second fine point by retracting the print material after the first fine point is printed and then moving the dispenser vertically relative to the first fine point before the dispenser is moved horizontally to the second fine point.
