Abstract: A method for preparing a vapor sensitive sacrificial support material. The method may include decomposing a polycondensed PEO polymer with heat in the presence of a graphene-like material to release PEO polymer radicals from the polycondensed PEO polymer, such that at least a portion of the PEO polymer radicals become trapped on at least a portion of a surface of the graphene-like material to form a coated graphene-like material, which may be defined as a structural reinforcement material. The method may further include forming the vapor sensitive water-soluble thermoplastic polyethylene oxide graft polymer. The vapor sensitive water-soluble thermoplastic polyethylene oxide graft polymer may include a polyethylene oxide polymer backbone. The vapor sensitive water-soluble thermoplastic polyethylene oxide graft polymer may further include one or more nanoscopic particulate processing aids. The structural reinforcement material may be uniformly dispersed in the vapor sensitive water-soluble thermoplastic polymer composite.

Abstract: A method for preparing a sacrificial support material for use in printing a three-dimensional (3D) article includes providing a water-soluble thermoplastic polymer composite including a water-soluble thermoplastic polyethylene oxide graft polymer having a polyethylene oxide polymer backbone, and from about 0.05% to about 10% by weight of the polyethylene oxide polymer backbone of at least one polar vinyl monomer grafted to the polyethylene oxide polymer backbone. One or more nanoscopic particulate processing aids may be uniformly dispersed in the graft polymer in an amount of from about 0.05% to about 10% by weight of the water-soluble thermoplastic polymer composite. The water-soluble thermoplastic polymer composite may have a viscosity in the range of about 100 to about 10,000 Pa-sec. The method may also include forming the water-soluble thermoplastic polymer composite into the 3D printable sacrificial support material.
