Abstract: A three dimensional printing system for manufacturing a three dimensional article includes a print engine, a receptacle, a pump motor system, a removable conduit assembly, and a resin container. The receptacle includes an upper portion with an opening and a lower interface portion. The removable conduit assembly includes: a fluid inlet extending upwardly from the lower interface portion; a pump head removably coupled to the pump motor system; a fluid outlet for supplying resin to the print engine. The resin container includes an internal reservoir and a leading and trailing end relative to a direction of insertion of the resin container into the receptacle. The resin container includes a fluid outlet that extends downwardly from the leading end. Installation of the resin container includes passing the leading end through the opening and lowering and coupling the leading end to the lower interface portion.

Abstract: A kit enables an efficient and contamination-free method of changing a resin (20) used in a three dimensional printer from a first resin to a second resin. The three dimensional printer includes a print engine (6) and a receptacle (42). The kit includes a conduit assembly (36) and a resin container (44). The conduit assembly (36) includes a fluid inlet (54) configured to be affixed in the receptacle (42) in an upward orientation, a pump head (52) configured to be coupled to a motorized pump actuator (90) in the receptacle (42), a first conduit (56) coupling the fluid inlet to the pump head (52), a fluid outlet configured to supply resin (20) to the print engine (6), and a second conduit coupling the pump head (52) to the fluid outlet (40).

Abstract: A resin container 44 is configured to provide a photocurable resin to a three dimensional printing system. The three dimensional printing system includes a receptacle configured to provide the resin to a print engine. The resin container 44 includes a housing 102 enclosing an internal reservoir which contains an impeller 128. The resin container 44 has a leading end 106 and a trailing 104 end relative to a direction of insertion or installation of the resin container 44 into the receptacle. The leading end 106 includes a fluid outlet 110 extending downwardly from a first lateral location, an electrical connector 114 extending downwardly from a second location, and a gear 112 coupled to the impeller 128 and extending downwardly from a third lateral location.
