Description
Technical field
The present invention relates to a kind of rapid shaping technique, and in particular to a kind of model layers section side being used in 3D printing
Method.
Background technology
3D printing, also referred to as increasing material manufacturing, it is one kind of rapid shaping technique.This technology is using mathematical model file as base
Plinth, with powdered-metal or plastics etc. can jointing material or light-sensitive material, by successively printing and bonding（Or solidification）Mode
Carry out constructed object.The characteristics of 3D printing maximum, can be met individual requirements for the complicated or personalized product of high accuracy
Production, 3D printing realize in difficulty that more very one raises in cost, technology.Meanwhile because being increasing material manufacturing, it is nearly free from production
Waste material, stock utilization can usually reach more than 90%.Therefore, 3D printing has and can not be substituted in terms of manufacture exemplar and mould
Advantage.
Using 3D printing technique implementation model print principle be：On some direction, with enough sections by three
Dimension module is subdivided into the thickness that can be printed, and obtains all profile informations intersected with model of being cut into slices on each layer, calculates printing
Path；According to printing path, bonded by the successively accumulation to printed material（Solidification）, model reconstruction is come out.
In the prior art, as shown in Figure 1, cut into slices as planar slice, the research to the microtomy of 3D printing, main collection
In section thickness selection on, hierarchical algorithm mainly has two kinds of even laminating and adaptive layered.Wherein, adaptive layered is
According to the surface complex situations of object, the lift height of model is changed automatically so that the layering that complicated surface has
Thickness is smaller, and the lift height that simple surface has is larger.For example, Chinese invention patent application CN104708824A is disclosed
A kind of 3D printing self-adapting slicing method of reserving model feature, judged by feature existence condition any in slicing profile information
Whether the section on adjacent two layer height there may exist feature, if there may exist feature, using minimum lift height
Secondary section is carried out the model data section, so as to improve printing precision on the premise of hierarchy number is reduced as far as possible.Therefore,
Section of the prior art is planar slice, and the research to section is concentrated mainly in the thickness selection of section.
However, for the 3D printing using bonding mode shaping, a difficult point is the strong of the 3D printing device of acquisition
Degree is inadequate, and particularly interfacial bonding strength has problem.To improve intensity, conventional thinking is to improve the bonding of material in itself
Property.But in the case where not considering material caking property itself, if it is possible to improve the intensity of print device, for 3D printing
Application will produce material impact.
The content of the invention
The goal of the invention of the present invention is to provide a kind of dicing method of 3D printing, by the improvement to dicing method, improves
The intensity of 3D printing device.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of dicing method of 3D printing, including under
Row step：

Piece is curved surface, and the intersection of the section of the lth layer and vertical direction is the curve of Sine distribution form, is formed on curved surface of cutting into slices
Rule, the distribution of uniform peak-to-valley；
(3) according to step（2）The hierarchy slicing information of acquisition, successively printer model.
In practical operation, it is possible to specify ad-hoc location is as sinusoidal central point, in printing with the central point
As anchor point.All sections of model are formed by lth layer.
Section is unrelated with internal structure based on the appearance and size of model.
In above-mentioned technical proposal, the Breadth Maximum of model is D, and the height of model is H, the sine curve or cosine curve
Amplitude be A, cycle d, thickness h, as H/D ﹥ 1, A ﹥ 2h, d ﹥ 4h, as H/D≤1, h≤2A≤2h, 2h≤d≤4h.
In above-mentioned technical proposal, the section has spatial sinusoidal curved surface, the spatial sinusoidal curved surface and at least one pair of phase
Mutually the intersection of orthogonal section is in Sine distribution, and curved surface is smooth, a peak, a paddy in cycle d be present.Thus, it is adjacent
The peak and valley that the sine curve in region is formed is alternately distributed.Peak-to-valley is alternately distributed, and increases lateral bonding force, so as to increase 3D
Print the intensity of part.
In above-mentioned technical proposal, the thickness of every layer of section is identical.
In being projected by the bottom surface of printing objects, when all directions are of different sizes, by the way of different directions do not wait the cycle
Cut into slices.Preferably, the curved surface has on each direction along the horizontal plane is no less than 4 cycles.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1st, the present invention breaches the thinking framework that planar slice is used in conventional art, creatively introduces sine surface
The curved surface of section is formed, unique uniform peak-to-valley is distributed the contact surface for considerably increasing adjacent interlayer, is not changing material sheet
On the premise of body caking property, the intensity of the device of 3D printing acquisition is considerably increased.Sine surface has smooth characteristic, does not increase
Oil (gas) filling device runs difficulty.
2nd, thickness is equal in the same slicing layer of the present invention, the discharge method of 3D printer and going out for conventional planar slicing mode
Material mode is identical, will not increase manufacture difficulty.
3rd, present invention employs main body constitution element of the sine curve as curved surface, curved surface to have extremely strong regularity, just
Reconstructed in implementation model.
4th, the cycle of sine surface orthogonal direction, amplitude and thickness are adjustable, are easy to according to technique adjustment printing solution, so as to
Obtain most strong part.
