Abstract: Techniques for improved efficiency of sintering in additive fabrication are described. According to some aspects, mechanisms for depositing and leveling source material are combined with a mechanism for heating the material. In some embodiments, one or more heating elements may be arranged to lead and/or follow a material deposition mechanism such that heat may be applied to the build region in concert with deposition of material. As a result of this technique, the heating and depositing steps may be performed closer together in time and/or heat may be applied more directly to the material than in conventional systems. As a result, greater control over material temperature may be achieved, thereby avoiding excess temperature exposure and subsequent undesirable changes to the material.

Abstract: Techniques for illuminating an interior of an enclosure in an additive fabrication device are described. According to some aspects, an additive fabrication device includes a build region into which source material may be disposed and at least one source of electromagnetic radiation configured to direct radiation onto the source material in the build region to thereby form a layer of solid material from the source material. A first heater may be included that is configured to heat at least a portion of the source material in the build region. In some embodiments, an enclosure surrounds the build region and comprises a refractive aperture. In some embodiments, at least one light source is arranged to direct light into the enclosure through the refractive aperture.

Abstract: Techniques for designing and fabricating thermal supports via additive fabrication are described. In some additive fabrication techniques, sufficiently high temperature differentials may contribute to any of a diverse array of part defects and failure modes. Additional volumes, referred to as thermal supports, may be fabricated along with a desired object such that the thermal supports adjusted, in a desired manner, temperatures that would otherwise be experience within the fabrication material during fabrication. For instance, the presence of a thermal support structure may serve to reduce changes in temperature experienced by the material between one or more adjacent layers during fabrication. According to some embodiments, thermal supports may be generated to be fabricated with a part so as to not be in contact with the part. Such a thermal support may reduce a temperature differential without affecting the finish of the fabricated object.
