A method and an apparatus for collecting a powdered material after a print job in powder bed fusion additive manufacturing may involve a build platform supporting a powder bed capable of tilting, inverting, and shaking to separate the powder bed substantially from the build platform in a hopper. The powdered material may be collected in a hopper for reuse in later print jobs. The powder collecting process may be automated to increase efficiency of powder bed fusion additive manufacturing.
摘要:
A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

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.

The application refers to a method for generating three-dimensional object models for an additive manufacturing process in a layer-by-layer manner, e.g. 3D-printing, and to generating control data for use by the print apparatus. The object models are generated from a geometric description and from object generation data, which comprise the print apparatus and attributes such as a halftone scheme, a print apparatus setting, an object structure and a print material coverage representation. The method is implemented in the form of a computer software product and generates data specific for each identifies printing device.

摘要:
Verification methods, systems, and computer program products verify the completion of assembly instructions used in light-manufacturing. Using position guides in a user interface, an in-use component is aligned and ready for verification through a first set of images of the in-use component. A visual highlight area on the user interface overlaying the in-use component indicates where to perform the assembly instructions. To create a traceable record, a second set of images are stored in an assembly record database when the assembler points a wand where the in-use component has been assembled. Another verification approach includes pointing an image capture device over the in-use component and receiving a first voice command authorizing image acquisition. A second voice command confirms accuracy of the image and proper assembly. Storing first and second voice commands and images of the in-use component being assembled in an assembly record database creates another traceable record useful for verification.
摘要:
The present invention extends to methods, machines, systems, and computer program products for producing multiple packaging products in a tiled configuration within source production material, enabling production of multiple packaging products in parallel. Embodiments include accessing item data identifying items that are to be packaged, and determining packaging requirements for each item. A pair of box sizes that satisfy the packaging requirements are selected for tiled production. A packaging production machine to be used is also selected. Selection of the box sizes and/or the packaging production machine is based on a collective analysis of packaging requirements, packing system characteristics, and packaging machine characteristics. Based on the collective analysis, it is determined how to allocate box production to the production machine, and the pair of box sizes is matched to the production machine. Box production instructions are generated and sent to the packaging production machine.
摘要:
Methods, systems, and computer program products are provided for determining a manufacturing capacity at a facility with assemblers performing assembly instructions in a computer directed assembly (CDA) system. Determining a manufacturing capacity includes selecting a production time interval for a product assembled using a sequence of assembly instructions. A scheduler system identifies assemblers available during the timeframe that have been trained and have performed the sequence of assembly instructions. Once this set of assemblers is identified, the scheduler projects an individual capacity for each assembler in the set of assemblers to perform the sequence of assembly instructions during the production time interval. The projected individual capacity is projected based on historical assembly performance data for each assembler stored in an assembly record database. The manufacturing capacity i s then generated by aggregating the projected individual capacity for each assembler to perform the sequence of assembly instructions over the production time interval.
