A support material toner particle for use in xerographic additive manufacturing includes a id='REI-00001' date='20200331' PVA polymer blend including a id='REI-00001' polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer id='REI-00002' date='20200331' blend id='REI-00002' to be within about 1° C. to about 20° C. of a desired build material toner Tg. A xerographic toner system includes a build toner material and a support toner material, the support toner material includes id='REI-00003' date='20200331' a PVA polymer blend including id='REI-00003' a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer id='REI-00004' date='20200331' blend id='REI-00004' to be within about 1° C. to about 20° C. of the build material toner Tg. A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.
