As shown in Figure 5 and Figure 6, another 3D printing system 1c is formed in the present embodiment, the part specifically selected includes：
Three cell modules, 1, three group of pull bar group 5, extruder head 2a, hott bed 3a and base 4a.Wherein the quantity of cell module 1 be three and
Be vertically installed at base 4a, the both ends of each pull bar group 5 be hingedly mounted on corresponding between installation end 11 and extruder head 2a.By
There is certain difference with embodiment one, embodiment two in the structure of composition, extruder head 2a, the hott bed 3a used in the present embodiment
With base 4a with slightly having difference, the core content of the non-combined scheme of these structures itself, Ke Yili in embodiment one, embodiment two
Solve and selected as needed for more set correlated parts, or the correlated parts of both of the aforesaid embodiment can also be used.
Parallel 3D printing system 1c is constructed in this implementation, three cell modules 1 form three z-axis, x, the seat of y-axis
Mark is projected in z-axis, and three installation ends 11 links x, the y for being moved to extruder head 2 and specifying in z-axis, in z coordinate, parallel connection
Formula 3D printing system is print system ripe in the prior art, and specific Automatic Control Theory, coordinated signals mode do not repeat.
Compared with embodiment one, embodiment two, the 3D printing system 1c that is built in this implementation, extruder head 2a can be quick
Move in space, there is the characteristics of print speed is fast, and be slightly short of in printing precision.
The be hinged fixed structure that can be dismantled can realize by various structures, such as rotating shaft and the bearing that is set in rotating shaft,
Bearing is pulled down the fractionation of the two can be achieved.Specifically, the be hinged fixed structure in the present embodiment includes detachable installation
Linking arm 14 in installation end 11, the mounting seat 21 for being removably mounted to extruder head 2a, the both ends of pull bar group 5 are respectively articulated with fixation
In on linking arm 14 and mounting seat 21, tearing open for pull bar group 5 and installation end 11 is realized by the dismounting of linking arm 14 and installation end 11
Unload, the dismounting of pull bar group 5 and extruder head 2a is realized by the dismounting of mounting seat 21 and extruder head 2.Linking arm 14 can use spiral shell
The structures such as bolt are fixed on installation end 11, and mounting seat 21 can also use the structures such as bolt to be fixed on extruder head 2, specific peace
It is not limited in assembling structure the present embodiment.
Be hinged fixed structure also includes the oscillating bearing 51 installed in the end of pull bar group 5, is arranged in the inner ring of oscillating bearing 51
511 connecting shaft 52, oscillating bearing 51 have outer ring and inner ring 511, in addition to providing and rotating, moreover it is possible to are deflected in certain angle
In the case of keep rotation connection relation so that pull bar group 5 can undertake certain lateral drift.Connecting shaft 52 can be fixed directly
In linking arm 14, mounting seat 21, pull bar group 5 mentioned above and the be hinged of linking arm 14, pull bar group 5 and mounting seat 21 are realized
It is be hinged, in other examples, connecting shaft 52 can also be directly anchored on installation end 11 and extruder head 2, pass through connection
The dismounting of axle 52 and the inner ring 511 of oscillating bearing 51 can also realize detachable be hinged fixed structure.
In other examples, it is also an option that the cell module 1 of other quantity, is combined, structure in other ways
It is arranged in the z-axis that can longitudinally lift into the 3D printing system with its x, y, z shaft model, such as by hott bed 3, selects in addition
Two cell modules 1 are as x-axis and y-axis and set extruder head 2；Or horizontal stacking sets two orthogonal lists on base 4
First module 1 is as x-axis and y-axis and installs hott bed 3, sets longitudinal cell module 1 to be used as z-axis, and extruder head 2 is set in z-axis.
Understand in summary, modular deformation 3D printing external member can at least construct embodiment one, embodiment two, implement
Three kinds of 3D printing systems in example three, these three systems have the characteristics of being easy to dismounting, cost of wheeling is low simultaneously, while are printing
Each has something to recommend him in speed, printing precision, a whole set of modular can be deformed 3D printing external member and selected as required wherein by user
Part assembling form the 3D printing system for meeting to require, such as need the knot in the fast then selection example three of print speed
