Abstract: In an example implementation, a method of extracting three-dimensional (3D) objects includes forming on a vibratory extraction platform, a build cake comprising a fused 3D object encased within build material and vibrating the extraction platform to break apart the build material and sift it through openings in the extraction platform.

Abstract: A build material management system for an additive manufacturing system is described in which a recovered build material tank (208) and a mixing tank (212) are provided. The recovered build material tank (208) comprises an outlet and a first build material filter (218b) for separating a gas flow from a build material flow. The mixing tank (212) comprises a second build material filter (218c). The mixing tank (212) is connected to the recovered build material tank (208) via a RBMT-to-mixer conduit (286). A controller (295) is provided to couple the second build material filter (218c) to a reduced pressure interface to transport build material from the outlet of the recovered build material tank into the mixing tank (212) via the second build material filter (218b). The controller (295) controls coupling of the first build material filter (218b) to the reduced pressure interface to transport build material from a build material source into the recovered build material tank (208). A corresponding method is provided.

Abstract: A building platform substrate for 3D printing in a Fused Filament Fabrication (FFF) 3D printer is disclosed. The platform substrate includes a paper layer that is re-pulpable in water, a water-soluble top coat layer on one side of the paper layer, a water-soluble adhesive layer on an other side of the paper layer, and a lay flat release liner on an exposed surface of the adhesive layer. A 3D printer having a removable Z-axis platen for accepting the building platform substrate and a method of manufacturing the platform substrate are also disclosed.
