    Abstract: Technologies are generally described to increase a surface smoothness of a 3D printed article implementing a water-based treatment using layer by layer (LBL) deposition. An initial 3D printed article having an anionic surface may be treated with a first aqueous solution comprising at least one polycation that may bind to the anionic surface to produce a first treated surface, which may be rinsed with water to remove the first aqueous solution. The first treated surface may be treated with a second aqueous solution comprising at least one anionic microparticle that may bind to the polycation to produce a final 3D printed article having a second treated surface, which may be rinsed with water to remove the second aqueous solution. The bound polycation and anionic microparticle may be present as a single layer in the final 3D printed article that may act as a conformal coating to increase the surface smoothness.

    Abstract: Various embodiments disclosed relate to melt-stabilized materials including ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants including the same. In various embodiments, the present invention provides a method of melt-stabilizing a material including UHMWPE. The method includes obtaining or providing a solid material including UHMWPE including a first concentration of free-radicals. The method includes coating at least part of the solid material with a liquid composition including at least one antioxidant, to provide a coated solid material. The method includes heating the coated solid material in an environment including oxygen, the heating being sufficient to melt at least part of the UHMWPE, to provide a heated material. The method also includes solidifying the heated material, to provide a melt-stabilized material including UHMWPE including a second concentration of free-radicals, wherein the second concentration of free-radicals is less than the first concentration of free-radicals.

    Abstract: The invention relates to a method for unpacking a component (11) produced by means of an additive product method from a particulate-material fill (9) of loose, unconsolidated particulate material, which fill is arranged together with the component (11) in a construction chamber (5) and surrounds the component (11). In order to unpack the component (11), the particulate-material fill (9) surrounding the component (11) is converted into a fluidized bed, such that the loose, unconsolidated particulate material is fluidized, and the fluidized unconsolidated particulate material is drained from the construction chamber (5) downward. The invention further relates to a device for use in the method.
