Abstract: Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.

Abstract: A system and method of additive manufacturing includes i) forming a first layer, the first layer may include at least one material chosen from an article material, a support structure material and an interfacial material. The method also includes ii) forming an additional layer on the first layer, the additional layer may include at least one material chosen from the article material, the support structure material and the interfacial material. The method also includes iii) repeating ii) one or more times to form a three-dimensional build may include an article and at least one support structure attached to the article at an interface, the interface may include the interfacial material formed during one or more of i), ii) or iii), and the interfacial material may include a preceramic. An interfacial material may include a preceramic or further include carbon, aluminum oxide, or silicon carbide.

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: A method of additive manufacturing includes i) forming a first layer, the including a material chosen from an article material, a support structure material and an interfacial material. The method includes ii) forming an additional layer on the first layer, including at least one material chosen from the article material, the support structure material and the interfacial material. The method also includes iii) repeating ii) one or more times to form a three-dimensional build may include an article and at least one support structure attached to the article at an interface, the interface may include the interfacial material formed during one or more of i), ii) or iii), the interfacial material may include a polymer. An additive manufacturing system includes a controller operatively connected to a reservoir, an ejector, and an actuator, the controller being configured to perform the method and form a printed article.
