The invention relates to a
fiber-reinforced multi-spray-head
cement paste 3D printing
machine which comprises a gantry type frame, an axis X, an axis Y, an axis Z, a
fiber composite spray head, a highpolymer material spray head, a
cement paste spray head, a material guide
pipe, a pressure pump and a storage pond. The
high polymer material spray head prints the outer contour of a three-dimensionalmodel through a layer-by-layer overlapping manner. After the
cement paste spray head prints the contour of certain layer height on the
high polymer material spray head,
cement paste with the volume space equal to that of the contour of a shell is fast extruded, and the three-dimensional model is filled. After the continuous
fiber spray head achieves filling of cement of certain
layer thickness, continuous fiber materials are laid on the surface of the cement, and the forming performance of the
cement paste is enhanced. After printing is completed, the plastic shell is removed through a hot melting manner, and a cement model is obtained. The fiber-reinforced multi-spray-head
cement paste 3D printing
machine is low in material cost, high in forming precision and forming performance and goodin surface quality, multiple material characteristics can be adjusted and controlled easily, and the fiber-reinforced multi-spray-head cement paste 3D printing
machine is used for direct forming of products such as
landscape architecture and artwork and has wide application prospects.
