Invention can also be is arranged to the multiinjector of the printhead 3D printing part overhead as shown in Figure 4 vertically upward
Printing equipment, or the multiinjector inclination of the printhead is arranged to 3D printing part offset as shown in Figure 5 down
Printing equipment, corresponding second, which electroplates the parts such as pole plate, does accommodation as depicted, and here is omitted.
Exemplary, metalwork is printed with printing equipment using the above-mentioned metalwork rapid shaping of the present embodiment, selection
The composition of electroplate liquid is as follows:
Operating condition:
50~60 DEG C of solution temperature
PH value 3.5~4.5
1~2A/dm of current density2
Specific print procedure is as follows:
1st, in control system 20 input metalwork 3D data, recognized by control system 20 generated after 3D data it is corresponding
Control signal is sent to corresponding part.
2nd, start two-dimension displacement system 100 to move to printhead 10 in specified location, start electroplating power supply 70.
3rd, first electrode 14, the second public electrode 15 and force (forcing) pump 30 are started, wherein in the different nozzles of multiinjector
Different first electrodes are not unified to open and close, but carry out respective open and close according to control signal:
The point printed for needs, does not start to that should put the first electrode of position, the spray of not actuated first electrode
The electroplate liquid that mouth sprays is in electroneutral, and the directly vertical directive second of electroplate liquid electroplates the point specified on pole plate, realizes that electrochemistry is sunk
Product, constitutes a plating point, completes the accumulation of a point, the electroplate liquid liquid for losing cation is recovered from electroplate liquid collection box
It is pumped back to plating liquid case.
For the point that need not be printed, start to the first electrode of position should be put, have been turned on first electrode correspondence
The electroplate liquid that sprays of nozzle, sensed by first electrode, the electrical characteristics of electroplate liquid are in non-neutral, and it is high that the electroplate liquid enters first
When pressing the narrow slit between public pole plate and the public pole plate of the second high pressure, deflect, then enter in the presence of high voltage electric field
Accumulator tank, is not involved in 3D printing, then recycled by recovery pump pumped back plating liquid case.
4th, drive printhead 10 to move by two-dimension displacement system 100, complete the accumulation of this layer.When a certain layer plating (electricity
Casting) after accumulation terminates, the control of control system 20 two-dimension displacement system 100 is moved, and starts another layer of accumulation.And short transverse is
No movement, by the range according to electroplate liquid, depending on the factor such as pressure, not necessarily often having accumulated one layer will move once.
5th, printing terminates, three-dimensional metal part printing shaping, and it is removed from the second plating pole plate 60.
Embodiment three
The present embodiment proposes a kind of metalwork rapid shaping Method of printing, and electrochemical deposition is successively formed using electroplate liquid
Or electrolytic etching, the printing of metalwork is carried out, during the electroplate liquid carries out electrochemical deposition or electrolytic etching, institute is controlled
State the electrical characteristics of electroplate liquid.
In the position for needing to carry out the electroplate liquid printing, the electroplate liquid is injected directly on the position, completes the position
The printing put.
At the position that need not be printed, change the electrical characteristics for spraying the electroplate liquid so that the electroplate liquid hair
Raw deflection, makes electroplate liquid be not present on the position that need not be printed.
Specifically, the present embodiment is printing (the specific knot of the printing equipment progress metalwork described in embodiment two
Structure and specifically used process can direct reference implementation example two description, here is omitted), the electroplate liquid carries out electrochemistry and sunk
During product, by controlling the keying of each first electrode 14, whether the selective electroplate liquid for spraying correspondence is powered to enter
The electric field of second public electrode 15 so that electroplate liquid is accumulated on the position for needing to print, in the position that need not be printed
Upper deflecting enters accumulator tank.
During the electroplate liquid carries out electrochemical deposition or electrolytic etching, participated in by control system according to a certain moment
The number of the plating fluid column of 3D printing, effectively and timely regulates and controls to total electroplating current output valve, makes each participation 3D printing
Electro-deposition point or electrolytic etching point physical dimension, it is always consistent during whole 3D printing.
With it is above-mentioned be only the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications should also be regarded
For protection scope of the present invention.
