A hybrid method of surface hardening metallic components using a combination of chemical modification achieved through additive manufacturing and/or diffusion-based processing with transformation-based processing using a high energy density heat source. The hybrid process results in increased surface hardness and/or increased average case hardness and/or increased case depth compared to either treatment individually.

The present disclosure provides a system for aiding in the removal of an article of manufacture from a build plate. The system may include a catch mechanism, namely a catch basket, a support surface to which the catch mechanism is mounted and a net disposed across the catch basket. The support surface may include a spring mechanism. The net may be disposed of at a distance above a bottom portion of the catch basket.

A processing system includes: a processing apparatus for processing an object; a rotation apparatus for rotating a holding part holding the object; a movement apparatus for moving at least one of the processing apparatus and the holding part; a measurement apparatus for measuring at least a part of the object held by the holding part; and a control apparatus for controlling the movement apparatus and the rotation apparatus based on a measured result by the measurement apparatus to rotate the holding part and to move at least one of the processing apparatus and the holding part

A processing machine (10) for building an object (11) from a material (12) includes a build platform (16), a platform mover assembly (20), a material supply (22), an irradiation device (26), and an analyzer system (30). The platform mover assembly (20) moves the build platform (16) about a platform movement axis (48X) and along the platform movement axis (48X). The material supply (22) supplies material (12) to build the object (11) on the build platform (16). The irradiation device (26) irradiates at least a portion of the material (12) with an energy beam (26A) to form the object (11) from the material (12) on the build platform (16). The analyzer system (30) is configured to monitor the energy beam (26A). The analyzer system (30) includes an alignment component (36) that rotates concurrently with the build platform (16) about the platform movement axis (48X), but that is inhibited from moving concurrently with the build platform (16) along the platform movement axis (48X).

An AAMP system includes a plurality of AAMP system stations disposed in an environment and configured to perform one or more AAMP processing routines, and a plurality of robots configured to autonomously travel within the environment, where one or more robots from among the plurality of robots include an auxiliary AAMP processing station configured to perform one or more auxiliary AAMP processing routines. The AAMP system includes a controller configured to select an AAMP system station from among the plurality of AAMP system stations to perform the one or more AAMP processing routines based on AAMP system operation data and select a robot from among the plurality of robots to initiate the one or more AAMP processing routines at the selected AAMP system station based on a digital model of the environment and robot operation data, where the robot operation data includes an auxiliary processing state.

Methods and devices for additive manufacturing of workpieces are provided. For analysis during production, a test is carried out using a selected test method. The test results are compared with simulated test results derived during a simulation of the manufacturing and testing. The test may use one or more of a laser ultrasound test unit, an electronic laser speckle interferometry test unit, an infrared thermography test unit, or an x-ray test unit.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.

A three-dimensional (3D) printing method and apparatus are disclosed for freeform fabrication of metal articles. 3D printed articles are formed from a build material comprising metal powder(s), polymer(s), and solvent(s). A coagulation agent, such as a nebulized non-solvent, is disposed onto/about the build material during 3D printing to cause at least partial solidification of the build material to form a green body structure. Multiple build materials can be mixed at a variable ratio to achieve a composition gradient through the green body structure. The 3D printed green body structure can be heated to remove some or all of the polymer, solvent, and/or for debinding. The debinded green body structure can be sintered at a specific sintering temperature or over a temperature gradient, for a period of time, in accordance with the sintering properties of the particular metal powder in the debinded green body structure, to form a finished metal part.

A 3D-printed reflective optic providing very high specific stiffness through the utilization of a hollow shelled design, with closed back, filled with high-stiffness internal volumetric space-filling open-cell lattice structures. High-stiffness, structurally-integrated, sacrificial structures are also included for the purposes of reduction or elimination of tooling during post-processing operations.
