  • POWDER SUPPLY ASSEMBLY FOR ADDITIVE MANUFACTURING
    Publication number: 20240131595
    Abstract: A processing machine (10) for building an object (11) from powder (12) includes a build platform (26A); a powder supply assembly (18) that deposits the powder (12) onto the build platform (26A) to form a powder layer (13); and an energy system (22) that directs an energy beam (22D) at a portion of the powder (12) on the build platform (26A) to form a portion of the object (11). The powder supply assembly (18) can include (i) a powder container (640A) that retains the powder (12); (ii) a supply outlet (639) positioned over the build platform (26A); and (ii) a flow control assembly (642) that selectively controls the flow of the powder (12) from the supply outlet (639).

  • Encoder head designs
    Patent number: 10378933
    Abstract: Encoder systems provide measurement and reference optical paths based on propagation in a common set of optical elements along paths that are displaced angularly or spatially. Associated measurement and reference beams are reflected by corner cubes to as to define first paths and second paths. The measurement and reference beams are combined to determine a work piece displacement in a manufacturing process.

  • Optical Imaging System and Method for Imaging Up to Four Reticles to a Single Imaging Location
    Publication number: 20100091257
    Abstract: A catadioptric optical imaging system and method is provided, in which up to four (4) reticles are imaged to a single imaging location (e.g. for imaging substrates), in a manner designed to provide high throughput, with a relatively high resolution, and with substrates whose size may approach 450 mm.
