Embodiment is only used for explaining the present invention, does not constitute limiting the scope of the present invention.
As shown in figure 1, a kind of 3D printing equipment based on self-propagating reaction, including printing portion, workbench portion and machine
Frame；Described printing portion includes printing backboard 9, and described printing backboard 9 is connected with frame 1 by dovetail groove, with ball-screw good fortune
Cooperation, can move up and down；Second controller 15, igniter 13, fluid port gripper shoe 5 is fixed on described printing backboard 9, described
Fluid port gripper shoe 5 and liquation fluid port 6 interference fit；Described printing backboard 9 is also with powder storehouse supporting plate 7 by dovetail groove even
Connect, described powder storehouse supporting plate 7 is coordinated with ball screw assembly, can move left and right, described powder storehouse supporting plate 7 is installed several self- propagating
Reaction powder storehouse 8；
Described workbench portion includes the first controller 14, also includes big palette 2, described big palette 2 pass through dovetail groove with
Frame 1 connects, and with ball screw assembly, cooperation, can move left and right；Little supporting plate 3 is connected with big palette 2 by dovetail groove, with ball wire
The secondary cooperation of thick stick, can move forward and backward；Stationary work-table 4 on little supporting plate 3；
Described first controller 14 controls workbench 4 all around to move and prints moving up and down of backboard 9, and described second
Controller 15 controls igniter 13 igniting to move left and right with powder storehouse supporting plate 7.
When carrying out 3D printing using apparatus of the present invention, dimensional measurement and material analysis are carried out to the part needing to print.Make
It is component modeling with computer 3 d modeling software CATIA, and the data of typing measurement.The threedimensional model building up is divided into two
Dimension section, and cross section information is transferred to the first controller 14 and second controller 15.Ground floor two transferred by first controller 14
Dimension cross section information, controlled motor 11, drive 3D printing workbench portion work around carrying out, the motion of four degree of freedom,
Make position to be printed apart from liquation fluid port 6 certain distance, and liquation fluid port 6 3D printing workbench portion relatively moves to first
The original position of the edge coordinate of layer two-dimensional section, sets filling rate as 0, and the number of plies is 1, starts working.3D printing workbench portion
Divide movement that liquation fluid port 6 is done relative motion, motion path summation constitutes the ground floor two dimension section that threedimensional model is divided into
Face.First controller 14 works simultaneously, and second controller 15 controls the work of self-propagating reaction part, reacting part by controlled motor
Divide and some little storehouses are divided into by ceramic material, each storehouse, built with aluminium base self-propagating reaction metal dust, is beaten according to model
The ground floor two-dimensional section of print needs the height value printing to determine reacting metal powder total amount, and mobile powder storehouse supporting plate 7 makes first
, just to liquation fluid port 6, ignited powder by igniter 13, melt powder storehouse bottom cover plate, make molten metal from head piece stream in storehouse
Go out, material is attached to position to be printed, when the first storehouse molten metal is used up, mobile powder storehouse supporting plate 7, make next storehouse just to liquation
Fluid port 6, next storehouse of igniting.After ground floor two-dimensional section prints and finishes, molten metal, also in semi-molten state, makes printing
Segment controller passes through motor 11 and controls printing backboard 9 to rise certain altitude, starts to print next layer.When printing is fully completed
When, printing portion controller cuts out liquation fluid port 6, and printing portion controller moves at Z axis full-size by printing backboard 9,
The computer recording time-write interval, print materials situation.Take off print member, clear up print platform, change self- propagating powder storehouse 8 He
Liquation fluid port 6.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
