Abstract: A multi-component adaptor assembly including a resin reservoir adaptor disposed on a printing surface of a preexisting additive manufacturing device, and including a build platform adaptor secured to a translatable arm of the preexisting additive manufacturing device. The resin reservoir adaptor is used to modify an existing resin reservoir by creating one or more smaller reservoirs within the larger housing, thereby reducing an amount of resin stored within the device to reduce resin waste. Moreover, the rotating and/or sliding build platform adaptor is designed to selectively contact one or more of the reservoirs of the resin reservoir adaptor, thereby selectively printing components of an additive manufactured process. The multi-component adaptor assembly allows for additive manufacturing projects using less resin with fewer waste products; simultaneous printing of identical structures; and the selective printing of different components of a structure during a single printing cycle.
