20230286219 · 2023-09-14 ·

A method for manufacturing a part by additive manufacturing including providing CAD data defining a geometry of the part, providing CAD data defining a geometry of a first clamping element, wherein the geometry of the first clamping element is determined in consideration of a geometry of a second clamping element such that the first clamping element can be clamped into the second clamping element for holding the part in a desired position for post-processing, generating machining data based on the CAD data defining the geometry of the part and the geometry of the first clamping element, and forming the part and the first clamping element by additive manufacturing process based on the machining data. The first clamping element has at least two parallel side surfaces and the second clamping element has two vice jaws positioned in parallel to each other along a longitudinal direction of the second clamping element.

METHOD OF SETTING MODELING CONDITION, ADDITIVE MANUFACTURING METHOD, ADDITIVE MANUFACTURING SYSTEM, AND PROGRAM

The present invention has: a setting step for setting lamination patterns respectively for an outer edge portion and an inner portion of a shape indicated by shaping data; and an adjustment step for adjusting a forming sequence such that, during manufacturing when the lamination patterns are used to laminate and thereby form the outer edge portion and the inner portion, the height of the already laminated outer edge portion is higher than the height of the inner portion that is being newly laminated. In the lamination patterns, the orientation of the heat source when a region positioned at a boundary with the outer edge portion is formed is set so as to be inclined at a prescribed angle toward the outer edge portion in a plan perpendicular to a movement direction of the heat source.

Part Manipulation Using Printed Manipulation Points

A manipulator device such as a robot arm that is capable of increasing manufacturing throughput for additively manufactured parts, and allows for the manipulation of parts that would be difficult or impossible for a human to move is described. The manipulator can grasp various permanent or temporary additively manufactured manipulation points on a part to enable repositioning or maneuvering of the part.

Enclosed additive manufacturing system

A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

Long And High Resolution Structures Formed By Additive Manufacturing Techniques

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.

Build material transportation with rotational latch

In one example in accordance with the present disclosure, a build material volume transportation device is described. The build material volume transportation device includes a shuttle to transport a build material volume. The shuttle includes an opening therethrough to receive the build material volume. The build material volume transportation device also includes a build tray to raise the build volume into the opening in the shuttle. The build material volume transportation device further includes a latch assembly to releasably secure the build tray to the shuttle. A tip of the latch assembly extends to interface with the aperture to secure the build tray to the shuttle. The tip rotates independently of the piston.

Chamber systems for additive manufacturing

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.
