THREE-DIMENSIONAL SHAPING DEVICE AND CALIBRATION METHOD OF THREE-DIMENSIONAL SHAPING NOZZLE
A three-dimensional shaping device includes: a dispensing unit including a nozzle; a stage having a shaping surface on which a shaping material is to be laminated; a position changing unit configured to change a relative position between the nozzle and the stage; a control unit configured to control the position changing unit; and a measurement module used to measure a difference of the nozzle from a reference position in the shaping surface based on a first position of the nozzle in the shaping surface and a second position of the nozzle in the shaping surface. The first position is a position in which the nozzle is assumed to be positioned by the control unit controlling the position changing unit. The second position is a position changed by the control unit controlling the position changing unit.

SIMILARITY-BASED ADDITIVE MANUFACTURING ALTERATIONS
In one example in accordance with the present disclosure, a method is described. According to the method, a characteristic of each of multiple three-dimensional (3D) objects to be printed is determined. 3D objects to be printed are grouped based on characteristic similarity. For a group of 3D objects to be printed, an additive manufacturing setting is altered based on the characteristics of the 3D objects to be printed that form the group.

RESIN MANAGEMENT SYSTEM FOR ADDITIVE MANUFACTURING
An additive manufacturing apparatus includes a stage configured to hold a component. A radiant energy device is operable to generate and project radiant energy in a patterned image. An actuator is configured to change a relative position of the stage relative to the radiant energy device. A resin management system includes a material deposition assembly upstream configured to deposit a resin on a resin support. The material deposition assembly includes a reservoir configured to retain a first volume of the resin and define a thickness of the resin on the resin support as the resin support is translated in an X-axis direction. The material deposition assembly further includes a vessel positioned above the reservoir in a Z-axis direction and configured to store a second volume of the resin. In addition, the material deposition assembly includes a conduit configured to direct the resin from the vessel to the reservoir.

Apparatus and methods for controlled validation of additive manufacturing systems
A method of improving production performance of an additive manufacturing system includes obtaining a first production plan and a second production plan, different from the first production plan, for the manufacture of a plurality of objects using a fleet of additive manufacturing apparatus, automatically generating a first allocation of a first quantity of the plurality of objects to the fleet of additive manufacturing apparatus using the first production plan, automatically generating a second allocation of a second quantity of the plurality of objects to the fleet of additive manufacturing apparatus using the second production plan, comparing a production performance of the first and second quantity of the plurality of objects after being manufactured by the fleet of additive manufacturing apparatus, and based on the comparison of the production performance, automatically regenerating the first and second allocations to change the first and second quantities.
