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.

Abstract: A method for the manufacture of a polymer foam composite includes forming a polymer foam that is at least partially uncured; contacting the formed polymer foam with a fibrous mat including a plurality of nonwoven fibers having an average diameter of 100 um or less under conditions effective to infiltrate a portion of the polymer foam into the mat, to provide a pre-composite; and curing the pre-composite to form the polymer foam composite. The pre-composite includes a polymer foam layer and an intermixed layer including the fibrous mat and the same polymer as the polymer of the polymer foam layer. The polymer foam composite includes a cured polymer foam layer and an intermixed layer integrally bonded to the first layer, wherein the intermixed layer includes the fibrous mat and a cured polymer the same as the polymer of the cured polymer foam layer.

Abstract: A compressible thermally conductive sheet comprises a plurality of through holes in a foam material substantially connecting first and second heat transfer surfaces to provide thermal pathways between surfaces. The though holes are filled with a non-foam thermally conductive composition in which thermally-conductive particulate filler is dispersed in a polymeric matrix. Also disclosed is a heat management assembly comprising the compressible thermally conductive sheet.
