    摘要： Substantially equal amounts of thermal energy may be provided over a build area of an additive fabrication device using as few as one heat source by selectively attenuating thermal energy emitted by the heat source. The thermal energy may be selectively attenuated by a structure that blocks portions of the thermal energy from being directly incident upon the build area such that the heat is normalized over the build area. The heat distribution over the build area may, in some embodiments, approximate the heat distribution produced by a flat field heating element, yet may be produced at comparatively lower cost and with less complex engineering.

    摘要： Some aspects provide a method of generating a support structure for an object, the support structure and the object to be fabricated via one or more additive fabrication techniques, comprising identifying one or more regions of the object as one or more regions to which mechanical support is to be provided, identifying one or more support points within at least a first region of the one or more regions, and generating the support structure for the object, the support structure comprising one or more support tips coupled to the object at the one or more support points, the support tips being generated based at least in part on a direction normal to the surface of the object at the respective support point.

    摘要： A method for producing a three-dimensional (3D) object on an additive fabrication device includes receiving, by a computer, print instructions for the 3D object. The print instructions include a sequence of print maps, each print map corresponding to a sub-instruction for producing a respective cross-section of the 3D object. The method also includes exposing, by an energy source, resin stored in a resin container at a print plane according to a first print map of the sequence of print maps, and modifying a second print map of the sequence of print maps. The method further includes exposing, by the energy source, resin stored in the resin container at the print plane according to the modified second print map.
