Abstract: A build plate for an additive manufacturing device and methods for the same are provided. The build plate may include a base and a sacrificial plate coupled with the base. The etch rate of the sacrificial plate in an etchant may be greater than an etch rate of the base in the etchant. A method for separating a 3D printed article supported on the build plate may include contacting the sacrificial plate with the etchant.

Abstract: An ejector for a printing system is disclosed. The ejector body may include an internal cavity, a nozzle in communication with the internal cavity, one or more segmented solenoid coils wrapped at least partially around the ejector body, and a piston disposed within the internal cavity of the ejector body. A method of ejecting liquid from an ejector is also disclosed, including introducing a material for ejection into an ejector cavity. The method of ejecting liquid from an ejector may include advancing a piston configured for translational motion within an ejector towards an ejector nozzle which may further include de-energizing a first segment of a segmented solenoid wrapped partially around the ejector, energizing a second solenoid segment of a segmented solenoid wrapped partially around the ejector. The method of ejecting liquid from an ejector may also include ejecting a drop of the material for ejection from the ejector nozzle.
