Abstract: A transparent pressure sensing film composition is provided having a matrix polymer; and, a plurality of conductive particles; wherein the matrix polymer comprises 25 to 100 wt % of an alkyl cellulose; and, wherein an electrical resistivity of the transparent pressure sensing film is variable in response to an applied pressure having a z-component directed along the thickness of the transparent pressure sensing film such that the electrical resistivity is reduced in response to the z-component of the applied pressure.

Abstract: The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.
