An additive manufacturing apparatus includes a first print module includes a first stage configured to hold a first component and a first radiant energy device. The resin support is configured to be positioned between the first stage and the first radiant energy device. A second print module includes a second stage configured to hold a second component and a second radiant energy device. The resin support is configured to be positioned between the second stage and the second radiant energy device. A control system is configured to translate the resin support based on a condition of the first print module and the second print module through the first print module and the second print module.

In an example, a method is described that includes generating a model for fabricating an item via an additive manufacturing process. The model includes a first region defining the item and a second region defining a sacrificial artifact whose presence disguises a physical characteristic of the item. The item and the sacrificial artifact are then fabricated in a common build batch via the additive manufacturing process.

A three-dimensional shaping device includes an ejection unit configured to eject a shaping material from a nozzle; a stage; a drive unit configured to change a relative position between the ejection unit and the stage; a cleaning mechanism provided with a brush and a blade; and a control unit. The control unit executes a cleaning operation of bringing at least one of the brush and the blade into contact with the nozzle by causing the nozzle to reciprocate in a manner in which the nozzle crosses the cleaning mechanism for a plurality of times in a cleaning processing. The control unit causes the nozzle to reciprocate such that the nozzle comes into contact with the brush or the blade at different positions in the cleaning operation. The control unit records at least one of material information on a type of the plasticizing material, a cumulative ejection amount of the shaping material ejected from the nozzle, and a use time of the nozzle in association with the nozzle.
