Cloth.
The described side of upper bush 4 is relatively fixed by screwed hole cooperation realization with barrel connector 7 and is connected, barrel connection
Part 7 coordinates realization to be connected with being relatively fixed for barrel 8 by screwed hole, ensures that raw material passes sequentially through the plup inlet on barrel 8
801st, the upper bush material path 403 on the connector material path 701 and upper bush 4 on barrel connector 7.
A kind of Method of printing of continuous fiber reinforced composite materials Screw Extrusion 3D printing device, comprises the following steps：
1) thermoplastic material is launched to the plup inlet 801 of feeding cylinder 8, then passes sequentially through connector material path 701, upper set
Cylinder material path 403 is extruded under the turning effort of screw rod 1 and promoted so as to be contacted with screw rod 1；Meanwhile continuous fiber then passes sequentially through
Fiber is sent into hole 402, fiber by hole 301, is finally combined with the inner molten state raw material of shower nozzle 2；
2) extrusion of continuous fiber composite material is realized by extrusion 201, coupled system control printing substrate X,
Y, under the motion in Z plane, so as to realize that the Screw Extrusion of composite prints product.
Beneficial effects of the present invention are：
The present invention is for wire feeding force is small, product efficiency is low, raw material shape in the extrusion molding of existing continuous fiber composite material
The shortcomings of modal constraint is big, by Screw Extrusion, retains synchronous feeding in original print procedure and send the technological advantage of fiber, from
And the high efficiency, high accuracy and high-adaptability product of continuous fiber composite material 3D printing are realized, hence for extrusion molding material
The 3D printing of material has very big influence and meaning
