  • Publication number: 20140263209
    Abstract: An apparatus for manufacturing includes: a build chamber including a build platform; a material dispenser configured to distribute a layer of powdered material over the build platform; a mirror arranged over the build platform and defining a mirrored planar surface; a first laser output optic configured to output a first energy beam toward the mirror; a second laser output optic adjacent the first laser output optic and configured to output a second energy beam toward the mirror; a first actuator configured to maneuver the first laser output optic and the second laser output optic relative to the build platform; a lens arranged between the mirror and the build platform; and a second actuator configured to maneuver the mirror to scan the first and second energy beams across the lens, the lens outputting the first energy beam and the second energy beam toward and substantially normal to the build platform.

  • Publication number: 20140265047
    Abstract: One variation of a method for controlling construction of a part over a build platform within a laser sintering device including an opaque door configured to seal the build platform within a build chamber includes: setting a lamp within the build chamber to an off state; detecting electromagnetic radiation within the build chamber based on an output of an optical sensor within the build chamber; in response to detection of electromagnetic radiation above a threshold flux, interrupting construction of the part within the build chamber; in response to detection of electromagnetic radiation below the threshold flux, setting the lamp to an on state to illuminate the build chamber; at an image sensor within the build chamber, capturing a digital image of the laser sintering site; and rendering the digital image on a digital display arranged on an exterior surface of the laser sintering device.

  • Publication number: 20140271328
    Abstract: One variation of a method for fusing and annealing powered material within an apparatus for manufacturing includes: depositing a layer of powdered material across a build platform; at a first time, projecting a first energy beam of a first power density onto an area of the layer of powdered material; and at a second time succeeding the first time, projecting a second energy beam of a second power density less than the first power density onto the area.

  • Publication number: 20140265046
    Abstract: One variation of a method for detecting a temperature at a laser sintering site within a field of view of an image sensor within a laser sintering device includes: based on a selected fuse temperature for a laser sintering build material, setting a first shutter speed for the image sensor, the first shutter speed corresponding to a detectable range of temperatures including an anticipated temperature at the laser sintering site; at a first time, capturing a first digital image of the laser sintering site with the image sensor at a first shutter speed; and correlating a light intensity of a pixel within the first digital image with a first temperature at the laser sintering site at the first time based on the first shutter speed.

  • Publication number: 20140265048
    Abstract: One variation of a method for constructing a three-dimensional structure within a additive manufacturing apparatus includes: reading an identifier from a cartridge transiently loaded into the additive manufacturing apparatus; initiating a build cycle; dispensing a layer of powdered material from the cartridge into a build chamber of the additive manufacturing apparatus; during the build cycle, selectively fusing regions of the layer; in response to completion of the build cycle, dispensing a volume of loose powdered material from the build chamber into the cartridge; and over a computer network, updating a computer file with data pertaining to the build cycle, the computer file specific to the cartridge and accessed according to the identifier.

  • Publication number: 20140265049
    Abstract: One variation of a method for constructing a three-dimensional structure within a additive manufacturing apparatus includes: reading an identifier from a cartridge transiently loaded into the additive manufacturing apparatus; based on the identifier, retrieving from a computer network a laser fuse profile for powdered material contained within the cartridge; leveling a volume of powdered material dispensed from the cartridge into a layer of substantially uniform thickness across a build platform within the additive manufacturing apparatus; and selectively fusing regions of the layer according to a fuse parameter defined in the laser fuse profile.
