The invention discloses a laminated structure
solid-phase additive manufacturing method. The method comprises the following steps that a wire material is heated to a
softening state, and a corresponding roller mould with an
isosceles trapezoid, a square and a plane shape is adopted by means of external force, in the
raw material forming process, filling and repairing are carried out alternately, so that a trapezoid shape, a
square shape, an inverted trapezoid shape and a trapezoid shape are formed by the raw materials layer by layer in sequence, additive manufacturing is carried out sequentially and circularly, and the raw materials are columnar wire materials. The method is a
solid-phase additive forming method which is free in
phase change, stable in
lap joint, in
extrusion /
forging type,compact in structure, precise in forming and low in cost. The technical scheme of the method can be widely applied to short processes, high quality, high efficiency and overall manufacturing of medium and large structural members, the practical
bottleneck which is difficult to control in forming and poor in performance reliability in the existing melting additive directly forming high-performanceaerospace component technology at home and abroad is broken through, and a practical new way is developed for high-quality, high-efficiency and directly integral manufacturing of the large and medium-sized and high-performance complex parts.
