    Abstract: Techniques to allow an additive fabrication device to dynamically adjust the size of a post metering volume for adjusting pressure of source material in the volume. These techniques may allow for greater control of material extrusion through an orifice and thereby mitigate or avoid issues of lag time between starting and/or stopping extrusion and/or in which there is unwanted emission of source material through the orifice. In some cases, techniques for adjusting the size of the post metering volume may include operating an actuator arranged in a channel that is coupled to the post metering volume. In some cases, techniques for adjusting the size of the post metering volume may include having a stator that is at least partially arranged within a chamber that defines the post metering volume and is free to move within the chamber.

    Abstract: According to some aspects, degradation of material in a sintering additive fabrication process may be mitigated or avoided by fabricating parts within a chamber that includes one or more thermal breaks. The thermal break may be implemented using a variety of structures, but generally allows material in the chamber close to the surface to be maintained at different temperatures than the material further from the surface. For instance, as a result of the thermal break, parts located within the material of the chamber that were formed earlier during fabrication may be kept cooler to avoid damage to the parts yet the upper surface (sometimes called the “build surface”) of unconsolidated material may be heated enough so as to require minimal additional energy exposure to trigger consolidation.

    Abstract: A post-processing device configured to be coupled to a three-dimensional printer. The post-processing device includes a head assembly that includes a release device and a collection device. A rail extends in a first direction, and the head assembly is configured to travel along the rail. The device also includes a pedestal assembly configured to be coupled to a base of the three-dimensional printer, and an opening device for opening a cover of the three-dimensional printer. At a parts collection location on the rail, the release device of the head assembly is configured to engage with a build platform of the three-dimensional printer to release printed parts on the build platform, and the collection device of the head assembly is below the build platform and is configured to collect the released printed parts.
