1. a fibre-grade is based on the 3D Method of printing of the antimicrobial product of reactive extrursion, it is characterized in that:

  • after melted to lactam monomers and/or internal ester monomer and auxiliary agent, plasticizer, under catalyst action, carry out polyreaction, add antibacterial before polymerization or in process, it is thus achieved that subject polymer;

    Then described subject polymer is printed through fusion sediment 3D, successively pile up and form 3 D workpiece;

    Described 3 D workpiece after heat treatment obtains final products;

    Described plasticizer is more than one in dibutyl phthalate, citrate, gallium chloride, lithium chloride, calcium chloride, clay, rare earth;

    Described heat treatment refers to and keeps 3-60min at 100-180 DEG C.
