The present invention relates to a 3D-printed cobalt-based alloy product comprising carbon, tungsten and chromium with very good mechanical and thermal properties as well as a method of preparing the 3D-printed product and a powder alloy. The alloy has a high carbon content leading to high carbide content but small and evenly distributed carbides. A method facilitating 3D printing of high carbide content alloys such as the present alloy is also disclosed.

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.

Methods, systems, and apparatus, for hybrid additive manufacturing of parts. In one aspect, a method includes providing a workpiece and manufacturing multiple additive layers on a surface of the workpiece. Manufacturing each of the multiple additive layers includes forming one or more formed layers on a surface of the workpiece by depositing a quantity of powder material on a growth surface, the growth surface inclusive of at least one of a first surface of the workpiece and a second surface of a previously formed layer, and applying a first amount of energy to the quantity of powder material to fuse the particles of the powder material into a formed layer fused to the growth surface, where the formed layer includes a formed surface, and further applying a secondary process to a particular area of the formed surface of the one or more formed layers on the workpiece.

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 plurality of interconnected products manufactured using additive manufacturing or 3D printing, wherein at least 50% of the products of the plurality of products are connected by a breakable connection to at least one neighboring product of the plurality of products, wherein the breakable connection is adapted to be broken apart by a tool adapted to apply force on at least one side of at least two products. A method, tool, and computer program product additively manufacture the products.

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.

A method of forming a vitreous bond abrasive article is presented that includes receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of a vitreous bond abrasive article precursor. The vitreous bond abrasive article precursor includes abrasive particles bonded together by a vitreous bond precursor material and an organic compound. The vitreous bond abrasive article precursor further comprises at least one of: at least one tortuous cooling channel extending at least partially through the vitreous bond abrasive article precursor or at least one arcuate cooling channel extending at least partially through the vitreous bond abrasive article precursor. The method also includes generating, with the manufacturing device by an additive manufacturing process, the vitreous bond abrasive article precursor based on the digital object.

A method for forming a multi-material part by selective laser melting includes the following steps. Modeling is performed by regularly distributing and arraying a combination of materials that meets forming requirements such that a part model is designed. The designed part model is subjected to a dimension compensation, a shape compensation, a chamfering setting, a margin design and a design of a process support to obtain a process model. The obtained process model is sliced into a series of layers. Type, distribution and boundary information of materials in each layer are collected to generate a control file. All materials required for part forming are loaded into an additive manufacturing equipment. After a state of the additive manufacturing equipment meets forming requirements, a part is formed under the control of the generated control file. Post-processing is performed after the part is formed.
