1. functional fibre-grade 3D based on reactive extrursion Method of printing, is characterized in that:

  • by lactam monomers and/or lactoneUnder catalyst action, carry out polyreaction after monomer and auxiliary agent, plasticizer are melted, before polymerization or during add function and helpAgent, it is thus achieved that subject polymer;

    Then described subject polymer is printed through fusion sediment 3D, successively pile up and form three-dimensional workPart;

    Described 3 D workpiece after heat treatment obtains final products;

    Described plasticizer is dibutyl phthalate, citrate, gallium chloride, lithium chloride, calcium chloride, clay, diluteMore than one in soil;

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