摘要： A multi-material component is provided including two members formed of different materials joined together at a multi-material join. The two members have complementary protrusions that form a multi-material join with a zig-zag interface, such that a tension between them is experienced in at least part as a shear force at the interface between the protrusions. The component further includes a third member connected to the first member by a lattice, which is capable of elastic deformation so as to substantially isolate the interface between the complementary protrusions from deformation of the third member such as that caused by thermal expansion. Methods of designing and constructing such a component in a single piece via additive manufacturing are provided. The component is particularly suitable for use in pylons connecting jet engines to aircraft wings.

摘要： An orthopedic device, such as an intramedullary nail for internal fixation of a bone and a method of manufacturing the same. The orthopedic device may be formed from a medical grade powder via an additive manufacturing process. The forming process may include heat treating the additive manufactured component and machining the heat treated additive manufactured component to form the orthopedic device. Further, the orthopedic device may be formed to include an internal sensor probe channel that extends within at least a portion of the wall of the device, but which does not protrude through an outer portion of the wall. Embodiments further include a dynamizing intramedullary nail that accommodate adjustments in the relative axial positions of one or more sections of the orthopedic device. The devise may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthopedic device.

摘要： The present invention relates to a method for preparing a metal powder intended for an additive manufacturing process, of the type that involves scanning a bed of powder by a near-infrared laser beam, characterized in that the method comprises: an initial step for selecting a powder, which has an optical reflectivity of higher than 70% for a wavelength ranging between 800 and 1500 nm; then a step for treating said powder, which is different from particle grafting, and which induces a physical and/or chemical surface modification of the grains of said powder, making it possible to lower its optical reflectivity, at the given wavelength. The invention also relates to the use of such a powder, the grains having, after treatment, a median grain size d50 of between 5 and 50 μm.

摘要： A permanent magnet formed by additively manufacturing magnetic phases and buffer phases is disclosed. The buffer phase(s) may improve performance, enhance mechanical properties and allow the magnet to better tolerate stresses such that defects such as cracking do not occur or are less likely to occur. The buffer phase may be a magnetic or non-magnetic material.

摘要： A calibration method for a system for powder bed-based generating of three-dimensional components by means of electromagnetic radiation, in particular such as a PBLS system, having a radiation source deflection unit and a raisable and lowerable carrier plate, above which a component is built, where, in order to calibrate the radiation source deflection unit, at least one virtual reference mark is used and, by means of a detector, a target-actual deviation between the virtual reference mark and a beam of the radiation source deflection unit is determined. An improved calibration method is achieved in that the at least one virtual reference mark is projected on a reference surface, which can travel vertically by means of the raisable and lowerable carrier plate, and independently of the vertical position thereof.

摘要： In a three-dimensional printing method example, a liquid functional agent is selectively applied. The liquid functional agent includes an alloying agent. A metallic build material is applied. The liquid functional agent is selectively applied before the metallic build material, after the metallic build material, or both before and after the metallic build material. The liquid functional agent patterns the metallic build material to form a composite layer. At least some of the metallic build material is exposed to energy to melt the at least some of the metallic build material to form a layer. Upon contact or after energy exposure, the alloying agent and the build material alter a composition of the composite layer.

摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

摘要： Systems and methods for adhesive-based part retention features in additively manufactured structures are disclosed. A structure includes a first AM part configured to connect to a second part via a primary connection applied to an interface between the first AM part and the second part. The structure includes at least one retention element including a secondary connection. The secondary connection includes a first adhesive configured to secure the first AM part and the second part. The secondary connection may be located to provide a connection between the first AM part and the second part.
