In the course of work of mechanism, the pressure value at nozzle may be caused to send out due to extraneous factor or the influence of Z axis height change
Raw mutation changes the uniformity of discharging to influence the quality of printed sample.
Summary of the invention
The object of the present invention is to provide a kind of 3D printer based on manostatic technique, make the material come out from nozzle always
Keep a certain amount of, so that the product printed be made to keep the uniformity of each section.
In order to solve the above technical problems, the present invention provides a kind of 3D printers based on manostatic technique, comprising: X,
Y, Z axis three-dimensional guide rail, extrusion mechanism, barrel, 3D printer body, lifting shaped platform, motor, nozzle mechanism, pressure sensing
Device, controller；
The X, Y, Z axis guide rail is connected directly with 3D printer body, and wherein X, Y-axis guide rail drive spray head in X, Y-axis side
It translates up；The lifting shaped platform is installed in the Z axis guide rail, and lifting shaped platform is driven to move along Z-direction
It is dynamic；
The nozzle mechanism is made of extrusion mechanism, barrel and nozzle, and wherein extrusion mechanism upper end is connected to the motor, and is squeezed out
Mechanism lower end is connected with barrel, is squeezed out the slurry in barrel by the extrusion movement of extrusion mechanism, the nozzle is connected to material
Cylinder lower section, realizes the extrusion of slurry；
Pressure sensor is arranged in detect the extrusion pressure at nozzle on nozzle, and the pressure value that will test is fed back to
Controller, so that the extrusion pressure at nozzle is maintained in constant range by controller.
In a preferred embodiment: the nozzle mechanism at work, if pressure sensor passes to the pressure of controller
When signal is controlled in error range, then 3D printer works on；If pressure sensor passes to the pressure signal of controller
When having exceeded error range, controller calculates offset pressure value based on current pressure values and feeds back to extrusion mechanism, changes and squeezes
The size of power output.
In a preferred embodiment: the Z axis position of the nozzle remains unchanged, and the lifting by going up and down shaped platform is realized
The Z axis of product is mobile.
Compared to the prior art, technical solution of the present invention have it is following the utility model has the advantages that
The present invention provides a kind of 3D printer based on manostatic technique, that is, provides a pressure detecting and pressure compensated side
Method, the present invention are mounted with that pressure value is passed to control by a pressure sensor, pressure sensor on the nozzle on 3D printer
Device processed when the pressure at nozzle changes, makes pressure recovery to original value by the power that controller adjusts motor.It can
So that the pressure at nozzle remains a fixed value, the material come out from nozzle is set to remain a certain amount of, to make
The product printed keeps the uniformity of each section.And a hoistable platform is provided, which is mounted on intermediate
On perpendicular guide rail, it is connected with the sliding shoe being connected with shaped platform above, the vertical motion of platform may be implemented, and not only limits
In the fixed platform that one is located on printing body.By this hoistable platform, the height that nozzle may be implemented in we is located always
Pressure value must change at the nozzle caused by same plane, that is, avoiding changing due to nozzle height.Pass through the X of spray head, Y-axis
And the Z axis realization of hoistable platform is three-dimensionally shaped.This structure makes the product uniformity to be formed preferable, is able to solve due to one
The non-uniform problem of extrusion output caused by pressure value variation caused by a little extraneous factors, guarantees the quality of printed product
Detailed description of the invention
Fig. 1 is the structural schematic diagram of 3D printer in the preferred embodiment of the present invention:
Appended drawing reference:
1- motor: 2-Y axis rail: 3-X axis rail:
4-Z axis rail: 5- goes up and down shaped platform: 6- nozzle:
7- barrel: 8- extrusion mechanism: 9-3D printer body:
Specific implementation method
Illustrate the specific embodiment of the invention or technical solution in the prior art in order to clearer, it below will be to specific
Required practical attached drawing is briefly described in embodiment or description of the prior art, can intuitively be found out very much, below
Attached drawing in description is some embodiments of the present invention.
With reference to Fig. 1, a kind of 3D printer based on manostatic technique, including X, Y, Z axis three-dimensional guide rail are present embodiments provided
2,3,4, extrusion mechanism 8, barrel 7,3D printer body 9, lifting shaped platform 5, motor 1, nozzle 6, pressure sensor and control
Device processed.
In the present embodiment, X-axis guide rail 3 and Y-axis guide rail 2 pass through control spray head machine by being mounted on 3D printer body 9
The movement of the mobile realization X, Y-axis of structure are to realize the spray printing in X, Y both direction.The lifting shaped platform 5 is connected to Z axis and leads
On rail 4, the Z axis for moving up and down control printing by control lifting shaped platform 5 in Z axis is moved.
The nozzle mechanism is made of pressing mechanism 8 and barrel 7 and nozzle 6, and wherein pressing mechanism 8 and barrel 7 are direct
It is connected, motor 1 is housed on pressing mechanism 8,.Barrel 7 and nozzle 6 are directly connected to.And it is installed on the nozzle 6 on 3D printer
One pressure sensor, pressure sensor detects the extrusion pressure at nozzle 6, and pressure value is passed to controller, works as spray
When pressure at mouth changes, make pressure recovery to original value by the power that controller adjusts motor.It can make nozzle
The pressure at place remains a fixed value, so that the material come out from nozzle is remained a certain amount of, to make to print
Product keep the uniformity of each section.
Specifically: the nozzle mechanism at work, if pressure sensor pass to controller pressure signal control
When in error range, then 3D printer works on；If the pressure signal that pressure sensor passes to controller has exceeded mistake
When poor range, controller calculates offset pressure value based on current pressure values and feeds back to extrusion mechanism, changes the big of extrusion force
It is small, the printing of Lai Shixian constant pressure.
In addition, the Z axis position of the nozzle remains unchanged in the present embodiment, the lifting by going up and down shaped platform is realized
The Z axis of product is mobile, this avoid nozzle 6 because of pressure value variation caused by moving in the Z-axis direction.
