The lower end of silk 5 forms the end of enlarged-diameter, and end is rotatably nested in the slot of fiber material nozzle carrier 1702.When screw thread 5
When rotation, position about the 17 relative nozzle seat of meeting of end changes, and band kinetodesma material nozzle carrier 1702 moves up and down, so as to adjust
The difference in height of flowing material nozzle 11 and fiber material nozzle 12 in z-direction.By adjusting the difference in height of two nozzles, can compensate
The difference of flowing material and fiber material diameter, also adjusts the overlying relation of two kinds of printing materials, is conducive to two nozzles of adjustment simultaneously
The matching status of two kinds of printing materials along same layer printing path print procedure, or can be printed simultaneously on the different layers.
Fig. 3 shows the structure of another printing equipment, and print head 1 and printing are realized by the rotation of print platform 2
The relative rotation of platform 2.Specifically, Fig. 3 print platform 2 unlike Fig. 2 can be along song by the driving of rotation drive device 8
The rotation of direction shown in line arrow, realizes the relative rotation of print head 1 and print platform 2.As shown in figure 3, in this embodiment
Print head structure can be greatly simplified.Print head 1 can rotate simultaneously in certain embodiments.In addition, flowing is also shown in Fig. 3
Expect that the dispenser replacement on feed pipe 13 carries out feeding using pumping installations 20, such as pumping installations 20 can be used for slurry
Flowing material is sent to flowing material nozzle 11 to squeeze out.It, can be in the distal end of flowing material feed pipe 13 when the longer situation of pipeline
Another pumping installations 20 is set close to the position of material source, accelerates feed, can avoid forming bubble in flowing material.
Above-described embodiment shows that the relative movement of print head 1 and print platform 2 can be by the mobile realization of print head 1
Can be the mobile realization of print platform 2, or both common mobile realize.Likewise, print head 1 is opposite with print platform 2
Rotation (or relatively rotate) can the rotation of nozzle carrier by print head 1 or thereon realize, be also possible to the rotation of print platform 2
Realize, or both rotate jointly realization.
Fig. 4 illustrates two nozzles in Fig. 1-3 and projects on print platform 2, and two nozzles are controllable to be set along same
It is mobile to determine printing path, naturally it is also possible to while being moved respectively along different printing paths.Print head 1 and print platform 2 are opposite
It is moved along printing path, while flowing material nozzle 11 and fiber material nozzle 12 and being relatively rotated along curve arrow and print platform 2, made
Material nozzle 11 and fiber material nozzle 12 must be flowed in print procedure while on preset printing path.
Fig. 5 illustrates the different location state that the twin-jet nozzle in Fig. 1-3 is moved along same printing path.Fiber material nozzle 12
