A system and method are disclosed for additively manufacturing an object having an internal chase. The system and method include evaluating a print design file that defines physical properties of the object to be printed with the additive manufacturing process to determine whether the object can be printed with a removable plug located inside the internal chase, and if so, modifying the print design file to include the removable plug. The object is then printed with the removable plug, which is removed prior to removing the support material.

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.

Methods for creating an aircraft turbomachine vane using additive manufacturing include additively manufacturing a vane on a bed of powder using selective laser melting, the additive manufacturing being performed on a support plate so that first or second circumferential edges are manufactured first directly on the support plate, at least one temporary support member being produced simultaneously with the first or second edges. The methods also include removing the temporary support member by breaking its connection with the leading or trailing edge with a tool that is engaged in at least one recess thereof.

A method for producing a support structure of a 3D model for 3D printing is provided. A method for producing a support according to an embodiment of the present invention comprises the steps of: dividing a surface constituting a 3D model into multiple surface patches; classifying respective divided surface patches according to geometric characteristics; and producing supports corresponding to the classified characteristics with regard to respective surface patches. Accordingly, during metal laminate manufacturing, the output stability may be improved while reducing the support producing process time. In addition, the surfaces may be expressed by different colors according to the result of geometric characteristic classification, and the supports may also be expressed by different colors according to the type, thereby playing the role of guide lines such that the user can recognize the shape of the surfaces and the type of supports to be installed on the corresponding surfaces. Moreover, the size of a support tip is determined in view of the thickness of the area in which a support is to be produced, thereby preventing the problem of output quality degradation which would otherwise occur because the support cannot move upwards through an output part.

The present disclosure provides a system for aiding in the removal of one or more test specimens from a build plate. The system includes an anchor portion disposed separate from the build plate. The anchor portion may include one or more attachment points for receiving and attaching one more stretchable bands. The stretchable bands may be sized to be stretched from each of the one or more specimens to the one or more of the attachment points. In this manner, a pulling force may be imparted on each test specimen, and the test specimen is moved away from the build plate during its removal. The system may be utilized particularly in conjunction with EDM and removing the test specimens using an EDM wire.

Methods for producing an object by generative manufacturing, a component, and a computer-readable medium. In one method, a sheet-like part is formed with bulges. In another method, a supporting structure is formed with an arch formed by arch segments converging in the buildup direction and meet at an arch tip. In another method, a supporting structure is formed with a strut of a cloverleaf-like cross-sectional shape. In another method, a supporting structure is formed with a sheet-like part connected to the object and formed to project obliquely forward from the object in the buildup direction. In another method, a supporting structure is formed with a sheet-like part extending substantially along the buildup direction, the sheet-like part formed with apertures. In another method, a supporting structure is formed with a sheet-like part connected to the object and, in a region of transition of the same to the object to be generated, has a perforation and/or a predetermined breaking edge along a contour of the object.

In an example, a three-dimensional (3D) printing kit includes a metallic build material composition; a binding agent; and a release agent for patterning a breakable connection. The binding agent includes a first latex binder. The release agent includes a white colorant including a white metal oxide pigment coated with a coating selected from the group consisting of alumina, silica, and combinations thereof; boehmite particles; a second latex binder; and an aqueous vehicle.
