Algorithm is covered to control the operating of servomotor to realize the orderly print out task of many material components.
Join Fig. 1 and with reference to shown in Fig. 5 a, 5b, the UV light sources in present embodiment include being connected to depositional control component 123
The first UV light sources 31 in outside and the 2nd UV light sources 32 being integrated on depositional control component 123.Wherein, the first UV light sources 31 are
Main UV light sources, for solidifying substantial amounts of material volume immediately, the solidification rate that can accelerate material improves print speed；2nd UV
Light source 32 is UV spot lights, is provided by the UV shot-lights for being integrated in depositional control component 123, for accurately solidifying small size deposition,
To be accelerated the curing process by the way that curing source is aimed at into certain material volume.
Depositing system in the present invention is many material nozzle depositing systems based on SLA formulas, and it is provided with supporting deposition control
Method processed, be specially：
Direct slicing algorithm technology is used first, by calculating the beginning and end each cut into slices, by all of shear layer
Combine part；
After the sequence of section is found, generate the nurbs curve of a closing to represent based on Open CASCADE bases
Incised layer profile；
Then according to the profile of each incised layer, the position of many material deposition heads is controlled by nozzle rotating device, and is carried out
Many material depositions and UV solidifications.
Comprising the following steps that when many material nozzle depositing systems carry out material deposition in present embodiment：
1st, feed arrangement is opened, and starts material being sent to material locker room via material feed conduit from feed well pump.Often
Individual material feed conduit is exclusively used in certain material, and its one end is connected to material carrying shield, and the other end is connected to Anchor plate kit.Charging
Device is by means of the bent axle pump material being connected on dedicated pump, and when material locker room is full of, feed arrangement is closed.
2nd, after the full required multiple material of material locker room filling and backing material of each nozzle, precipitation equipment is opened
Beginning depositing operation.Air compressor is opened, and keeps the constant pressure on Anchor plate kit.Need to control the pressure needed for each nozzle
Power, and the below equation obtained from Poiseulle laws can be used to calculate：
Wherein, P is the pressure of nozzle, and V is deposition flow velocity, and η is efficiency, and l is nozzle length, and t is the unit time, and r is spray
Outspoken footpath.Deposition flow velocity is by the Stress control that is applied on pressure assembly, and the pressure of each nozzle depends on the material of nozzle tip
Expect property and geometry.Therefore, the pressure of each nozzle is adjusted according to required flow.
3rd, by close to nozzle depositing system, moving Z axis to carry out first time deposition.The motion of Z axis is by servomotor control
System, servomotor can move up or down Z axis.
4th, to first time laydown adjustment spray nozzle device, required material nozzle is selected first, and seven nozzles are arranged on connection
Onto the rotating disk of servomotor, servomotor can be rotated both clockwise and counterclockwise 180 ° of nozzle.
5th, adjustment Z axis after, carry out depositional control, and select nozzle carry out first time material deposition with carry out continuous precipitation or
Sedimentation deposition.When limiting material working tool path during pre-processing, depositional control actuating is predefined.Depositional control allows to
Accurately control amounts of deposited material, it is important that it is to be understood that the Stress control that flow is applied by pressure plare, but depositional model is (even
Continuous or decline) controlled by depositional control component.For quality and precision, pressure mechanism and depositional control are required for perfect coordination.
6th, it is the solidification process successively completed after material deposition process.However, when multilayer material is deposited, it is necessary to layer
In every kind of material solidified.Material solidification process can be completed by using main UV light sources or UV spot lights, and this depends on
In the material quantity, geometry and the area that need to solidify.When multiple material is to deposit on a small quantity and more frequently, according to material
Property and light trigger intensity, different materials will need different UV luminous intensities, it is impossible to be consolidated using main UV light sources
Change, therefore UV spot lights are used.The processing of UV spot lights is relatively slow compared with main UV light sources but more accurate, it is easy to control.
Join shown in Fig. 6 a, when more than two material is deposited in identical layer, then can not possibly use first in Fig. 6 b
UV light sources 31 are (main UV light sources) to solidify, because different materials will need different UV luminous intensities to solidify.In this feelings
Under condition, main UV is light source curing to cause excessive material to solidify, while solidifying another material under same layer, this will be to solidification
Layer produces geometrical defect.In order to solve this problem, shown in ginseng Fig. 6 c, the 2nd UV light sources 32 (UV spot lights) can be used, it can
For integrated ultraviolet rays collection lamp, this may increase the time of solidification process, but when solidifying multiple material within the same layer,
Preferably control and precision can be provided.When first layer solidifies, Z axis is moved down, it is allowed to which next layer of deposition starts and repeat to follow
Ring, until the whole deposition cures of object are completed.
As can be seen from the above technical solutions, the invention has the advantages that：
1st, the present invention can deposit more than two kinds structure materials, can print the parts more than two kinds of materials；
2nd, the present invention sets servomotor to drive nozzle rotation, can realize the precise Printing of many material parts；
3rd, the present invention is provided with unique Anchor plate kit, the feeding for realizing exterior material that can quickly, stably；
4th, the present invention is provided with depositional control component, and the component is made up of an electromagnet system, when activated can be with
The deposition materials continuously or in droplet formation, can realize accurate control and the deposition of material；
5th, the present invention is provided with the first UV light sources on the outside of printing nozzle, it is possible to achieve the large volume solidification of material, improves
Print speed；The 2nd UV light sources are integrated with depositional control component, UV hot spots can be formed, for accurately solidifying corpusculum deposition
Product, to be accelerated the curing process by the way that curing source is aimed at into certain material volume, improves print quality.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
