Depositing system in the utility model is more material nozzle depositing systems based on SLA formulas, and it is provided with supporting sink
Product control method, it is 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, a nurbs curve closed is generated to represent based on OpenCASCADE bases
The profile of incised layer；
Then according to the profile of each incised layer, the position of more material deposition heads is controlled by nozzle rotating device, and is carried out
More material depositions and UV solidifications.
Comprising the following steps that when more 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 filling of the material locker room of each nozzle full required multiple material and backing material, 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.For deposition flow velocity by the Stress control that is applied on pressure assembly, 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, adjust 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 deposits, 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 material quantity, geometry and area that needs 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, easily controllable.
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 that (main UV light sources) solidifies, because different materials will need different UV luminous intensities to solidify.In this feelings
Under condition, main UV light sources solidification may cause excessive material to solidify, while solidify another material under same layer, and 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 moves down, it is allowed to which next layer of deposition starts and repeat to follow
Ring, until object whole deposition cure is completed.
As can be seen from the above technical solutions, the utility model has the advantages that：
1st, the utility model can deposit more than two kinds structure materials, can print the parts more than two kinds of materials；
2nd, the utility model sets servomotor to drive nozzle rotation, can realize the precise Printing of more material parts；
3rd, the utility model is provided with unique Anchor plate kit, the feeding for realizing exterior material that can quickly, stably；
4th, the utility model is provided with depositional control component, and the component is made up of an electromagnet system, when activated
Can continuously or in droplet formation deposition materials, accurate control and the deposition of material can be realized；
5th, the utility model 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,
Improve print speed；The 2nd UV light sources are integrated with depositional control component, UV hot spots can be formed, for accurately solidifying corpusculum
Deposition is accumulated, by the way that curing source is aimed at into certain material volume to accelerate the curing process, to improve print quality.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
