Rise.And the technology such as traditional machining, casting, the Production requirement of various workpiece, particularly shape cannot be fully solved
There is the workpiece of emptying aperture the special or inside of shape.However, the development of 3D printing technique (three-dimensional printing), but to the difficult problem that these manufacture
Bring a slim chance of survival.And three-dimensional printing technique, accelerated model molding can be not only provided, for some workpiece, it might even be possible to
Finished product or the semi-finished product molding of enough accuracy are directly provided.
3D printing technique has been developed a lot of years in fact.From selectivity laser sinter molding (Selective Laser
Sintering, SLS), three-dimensional powder cohere (3DP), layer separated growth (Laminated Object Manufacturing,
LOM) the fused glass pellet (Fused Deposition Modeling, FDM) of main flow up till now, or even newest light is solid
Change (DLP) technology, all successfully develop, and put into production.Current three-dimensional printing technology, using fusing or softening plasticity
The method of material manufacturing " ink " of printing, mainly with plastics, metal, ceramic main.However, workpiece body major part is all
Single material, solid color, although some printing techniques can be printed using multiple material, but every kind of material only has
A kind of color.Therefore, if the workpiece being intended to using three-dimensional printing molding colour, can become very loaded down with trivial details with complicated.
Content of the invention
Based on the technical problem that background technology is present, the present invention proposes a kind of color model 3 D-printing method, favorably
In three-dimensional colour model colouring work is simplified, colouring quality and efficiency is improved.
A kind of color model 3 D-printing method proposed by the present invention, prints base material model, Ran Hou initially with base material
Base material model extrinsic stain, obtains color model, comprises the following steps that：
Color model supplemental characteristic is obtained, generates color model figure；
Color model figure is parsed, obtains skinning layer and base material model；
Base material model being cut into slices, hierarchical diagram is extracted, colored region cutting is carried out to skinning layer, extracts multiple monochromatic areas
Domain, and to each monochromatic areas design spraying path；
Base material model is printed according to hierarchical diagram, and according to monochromatic areas and spraying path, base material model spray coated paint is carried out
Coloring.
Preferably, the concrete mode for carrying out colored region cutting to skinning layer is to choose the corresponding monochrome of color A, color A
Region is A0, extracts and is enclosed in the monochromatic areas around A0 with the border of point-rendering monochromatic areas A0 of monochromatic areas A0 intersection
Line A1, boundary line A1 can include a plurality of closure lines, spray what path passed through to cover with reference to boundary line A1 and monochromatic areas A0
Base material model surface region lines trend is designed, and spraying path width can be 1um～100um.
In the present invention, base material model is printed separately to be carried out with surface coloring, is conducive to improving color model printing effect,
Reduce work interference as far as possible, improve qualification rate.
A kind of color model 3 D-printing method that the present invention is provided, is decomposed by skinning layer cutting, obtains monochromatic areas,
And spraying path is designed to each monochromatic areas, painted to monochromatic areas one by one according to spraying path, orderliness is clear, and streamline is put down
Sliding, color model lines are moved towards with adaptability height, advantageously ensures that the homogeneous color of coloring is fresh and alive.
Step of the present invention is simple, reasonable in design, overcomes prior art neutral body and prints asking for colouring intricate operation complexity
Topic.
Description of the drawings
Fig. 1 is a kind of color model 3 D-printing method flow chart proposed by the present invention.
Specific embodiment
As shown in figure 1, a kind of color model 3 D-printing method proposed by the present invention, prints base material mould initially with base material
Type, then in base material model extrinsic stain, obtains color model, comprises the following steps that：
S1, acquisition color model supplemental characteristic, generate color model figure.
Specifically, color model image can be obtained by 3-D scanning, and color model figure is obtained by graphics process.
S2, color model figure is parsed, obtain skinning layer and base material model.
Base material model is the main body support section of color model, and skinning layer is for covering in base material model paint layer.
S3, base material model is cut into slices, extract hierarchical diagram；Colored region cutting is carried out to skinning layer, extracts multiple lists
Zone domain, and to each monochromatic areas design spraying path.
Layering accumulation is more ripe printing technique in three-dimensional printing technology, extracts layering by cutting into slices in the step
Figure, is that base material model three-dimensional printing is laid a good foundation.
The composition of skinning layer directly depends on the number of species of color model colouring.
In step S3, the concrete mode for carrying out colored region cutting to skinning layer is to choose object color component A, color successively
The corresponding monochromatic areas of color A be A0, extract be enclosed in the monochromatic areas around A0 with the point-rendering list of monochromatic areas A0 intersection
The boundary line A1 of zone domain A0.
It should be noted that the boundary line A1 of monochromatic areas A0 may include the lines of a plurality of closure, monochromatic areas A0 are
The area sum that these closure lines are surrounded.This is because, the surface of color model there may be the identical but not phase of multiple use colors
The region of connection, so the quantity of monochromatic areas is but equal to the number of species of colouring.
In step S3, the base material model surface area that path passes through to cover is sprayed with reference to boundary line A1 and monochromatic areas A0
Domain lines trend is designed.
S4, according to hierarchical diagram print base material model, and according to monochromatic areas and spraying path to base material model spray coated paint
Coloured.
In the step, coloring carry out after the completion of base material model, so the printing of base material model be continual carry out,
Be conducive to improving printing effect.
In the step, coloring is carried out successively according to color, i.e., each monochromatic areas are coloured successively.In this way, can keep away as far as possible
The colouring work for exempting from multiple color is interfered and is obscured.
In present embodiment, spraying path width can be 1um～100um, can according to base material model surface lines circumference with
And the width of monochromatic areas boundary line determines.Specifically, spraying path width is directly proportional to base material model surface lines smoothness,
Also it is directly proportional to the width of monochromatic areas boundary line.
In present embodiment, base material model is printed separately to be carried out with surface coloring, is conducive to improving color model printing
Efficiency, reduces work interference as far as possible, improves qualification rate.
In present embodiment, decomposed by skinning layer cutting, monochromatic areas are obtained, and each monochromatic areas are designed with spraying road
Footpath, painted to monochromatic areas one by one according to spraying path, orderliness is clear, and streamline is smoothed, and color model lines are moved towards to adapt to
Property high, advantageously ensure that the homogeneous color of coloring is fresh and alive.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, should all be included within the scope of the present invention.
