    Abstract: Disclosed herein is a method comprising growing a shim by disposing a mandrel having an optional textured surface in an electrolytic bath, where the shim contains a negative image of the optional textured surface formed by electrolytic deposition of a metal; affixing the shim working-side down on a reference plane using a fixture; optically scanning the shim to reverse engineer a geometry of a non-working surface, where reverse engineering a geometry of the non-working surface includes developing a profile of the non-working surface and the thickness of the shim; and adding a material to the non-working surface of the shim via additive manufacturing to form a tool insert.

    Abstract: Disclosed herein is a template comprising a soluble polymer having disposed thereon a texture; where the texture comprises a pattern comprising a first plurality of spaced features; the spaced features arranged in a plurality of groupings; the spaced features within a grouping being spaced apart at an average distance of about 1 nanometer to about 500 micrometers; each feature having a surface that is substantially parallel to a surface on a neighboring feature; each feature being separated from its neighboring feature; and wherein the groupings of features being arranged with respect to one another so as to define a tortuous pathway; where the template in in the form of a free-standing film that has a maximum thickness of 1.5 millimeters and a minimum thickness that is no greater than 40 percent of the maximum thickness; where the surface area of the textured surface is at least greater than 10 cm2.

    Abstract: Disclosed herein is a multilayered article comprising a first layer having a surface texture on a first surface; and a second layer contacting the surface texture on the first layer; where the surface texture comprises a plurality of identical patterns; each pattern being defined by a plurality of spaced apart features attached to or projected into the first surface, at least one spaced apart feature having a dimension of about 1 nanometer to about 1 millimeter, the plurality of features each having at least one neighboring feature having a substantially different geometry, wherein each pattern has at least one feature which is identical to a feature of a neighboring pattern and shares that feature with the neighboring pattern, wherein an average spacing between adjacent spaced apart features is about 1 nanometer to about 1 millimeter in at least a portion of the first surface, wherein the plurality of spaced apart features are represented by a periodic function.

    Abstract: Disclosed herein is a die assembly comprising a first attachment block having a passage, an inlet port and an exit port; where the passage is operative to transport a molten material from the inlet port to the outlet port; a die; and a conduit; where the conduit comprises a passage that is operative to transport the molten material from the first attachment block to an entry port of the die; where the die comprises a first outer tube; and an extrusion pin that comprises a post and fins; where the extrusion pin is located in the first outer tube using the fins and where the post extends from the fins in a direction away from the entry port of the die; and where the post comprises one or more passages; where at least of these passages open to the atmosphere to provide for pressure equalization; and a travelling template; the template being operative to contact an extrudate that emanates from the die and to transfer a texture to a surface of the extrudate by virtue of pressure applied by a guide tube to the extrudate via the travelling template.
