摘要： A method of improving production performance of an additive manufacturing system includes obtaining a first production plan and a second production plan, different from the first production plan, for the manufacture of a plurality of objects using a fleet of additive manufacturing apparatus, automatically generating a first allocation of a first quantity of the plurality of objects to the fleet of additive manufacturing apparatus using the first production plan, automatically generating a second allocation of a second quantity of the plurality of objects to the fleet of additive manufacturing apparatus using the second production plan, comparing a production performance of the first and second quantity of the plurality of objects after being manufactured by the fleet of additive manufacturing apparatus, and based on the comparison of the production performance, automatically regenerating the first and second allocations to change the first and second quantities.

摘要： Methods, systems, and/or apparatuses for making an object on a bottom-up stereolithography apparatus that includes a light source (11), a drive assembly (14), optionally a heater (34) and/or cooler (34), and a controller (15). The light source, optional heater and/or cooler, and/or the drive assembly have at least one adjustable parameter that is adjustable by said controller. An example method comprises (a) installing a removable window cassette (12) on said apparatus in a configuration through which said light source projects, said window cassette comprising an optically transparent member (12a) having a build surface on which an object can be produced, and with said optically transparent member having at least one thermal profile associated therewith; and then (b) modifying said at least one adjustable parameter by said controller based on said at least one thermal profile of said optically transparent member; and then (c) producing the object on said build surface from a light-polymerizable liquid by bottom-up stereolithography.

摘要： An additive manufacturing system may include an additive manufacturing apparatus on which a process of producing a three-dimensional object from a material can be performed; an additive manufacturing process controller operatively associated with the additive manufacturing apparatus; and a first memory device operatively associated with the additive manufacturing process controller. The first memory device may include first and second stable release process programs each comprising a first subset of operations executable by said process controller. The system may include a second memory device comprising another stable release process program comprising a second subset of operations executable by said process controller. The system may include a selector configured to choose one of the stable release process programs to run on said process controller when producing a three-dimensional object on the additive manufacturing apparatus.

摘要： Various embodiments described herein provide a method of making an object from a three-dimensional geometry file and a light polymerizable resin on a light-transmissive window by projection of light through the window in a bottom-up stereolithography process. The method may comprise: slicing the file into a series of sequential images. Temperature fluctuations in the resin may be calculated for at least some of the sequential images upon light polymerization thereof based on sequential exposure of the resin to light, the light corresponding to the series of sequential images. During producing of the object, the production may be modified based on the calculated temperature fluctuations by: (i) reducing production speed during at least a portion of the production; (ii) activating a window cooler during at least a portion of the production; or (iii) increasing production speed during at least a portion of the production.

摘要： A method of making a three-dimensional object from a light polymerizable resin, includes the steps of: (a) producing an object adhered to a carrier plate by light polymerization of the resin in a bottom-up stereolithography process (e.g., continuous liquid interface production); (i) the object including a carrier plate adhesion portion, a main body portion, and a circumferential boundary portion included in the carrier plate adhesion portion and optionally extending into at least part of the main body portion; (ii) the stereolithography process including overexposing the boundary portion (as compared to the exposure of the adhesion portion or main body portion) with light; (b) optionally cleaning the object; and then (c) optionally baking the object to produce a further cured three-dimensional object.
