The personalized customization of the accurate model such as structure complexity, possesses cost is low, the cycle is short, automaticity is high, precision is high, added value is high etc.
Advantage, it is more biologic medical, Aero-Space, Videl education, cultural creative, Fashion Design, mold former, toy etc. are applied to
The product development of industry and parts manufacture.The general Making programme of 3D printing technique is：(1) accurate data are obtained, are passed through
Digital computer technology, establish threedimensional model file；(2) suitable printing technology is selected, model file is imported into 3D printing
Equipment；(3) by way of successively accumulation molding material and backing material, the automated production of implementation model；(4) model is entered
Row post processing, removes backing material, to obtain the product for possessing complete structure.
The post processing for removing backing material is the important component of 3D printing technique and must directly affected through one of link
Size, structure and surface property of final product etc..In the 3D printing technique using organic material, backing material is often selected
The water-soluble or low-melting material easily removed, for filling the hollow structure of model, wherein wax pattern material is most heavy at present
One of backing material wanted.Remove wax pattern backing material conventional method be：The model of 3D printing is heat-treated, treats that wax melts
After change, further cleaned by organic solvent, the wax of residual is removed with dissolving.Cleaned at present using simple edible oil
Method, it tends to be difficult to thoroughly remove remaining wax, or even wax-oil mixture is remained in fine structure, cause sample after the drying
Surface is covered by white wax layer or fine structure is filled by wax mixture, and this outward appearance, structure and performance to sample are all
Harmful effect will directly be produced.
The content of the invention
The shortcomings that for existing 3D printing post-processing approach and deficiency, the present invention propose a kind of removing 3D printing wax pattern branch
The method of timbering material.This method mainly applies a kind of new organic mixed solvent, at a certain temperature to using wax pattern
The 3D printing sample of backing material is soaked, and thoroughly removes the wax of residual, and the final 3D printing sample without wax is obtained after drying.
This method have it is low to environmental requirement, simple to operate, prepare easily, cost is low, efficiency high, the spy for not damaging resin molding material
Point.
The object of the invention is achieved through the following technical solutions：
A kind of method for removing 3D printing wax pattern backing material, comprises the following steps：By alcohol organic solvent, alcohol Type of Collective
Thing organic solvent and vegetable oil stir according to a certain percentage, and organic mixed solvent is made；At a certain temperature, by 3D printing
Sample is placed in organic in the mixed solvent immersion, after removing dewaxing backing material, takes out 3D printing sample and is washed, obtained after drying
Obtain the final 3D printing sample without wax.
Described alcohol organic solvent is one kind in ethanol, propyl alcohol, isopropanol, butanol and isobutanol etc..
Described alcohols polymer organic solvent is one kind in polyethylene glycol, polypropylene glycol and polytetramethylene glycol etc..
Described vegetable oil is one kind in soybean oil, peanut oil, sesame oil, palm oil, coconut oil and rapeseed oil etc..
Described organic in the mixed solvent alcohol organic solvent and the volume ratio of alcohols polymer organic solvent are 1:1, plant
The volume of thing oil is the 0~100% of organic mixed solvent cumulative volume.
The volume of the vegetable oil is preferably the 40~80% of organic mixed solvent cumulative volume.
The scope of described temperature is 40~80 DEG C.
Described 3D printing sample is the 3D printing sample using wax pattern backing material.
The principle of the present invention be according to the similar rule that mixes, configuration it is a kind of with wax chemical composition polarity with it is close in structure
Mixed solvent.The main chemical compositions of wax are aliphatic acid, lipidol and grease, with alcohols, the alcohols polymer of the invention chosen
It is larger with the mutual solubility of vegetable oil, therefore under the appropriate temperature conditions, wax backing material can be directly dissolved in the mixed solvent.
Because the organic principle of wax is more, therefore mixed solvent is substantially better than single solvent to the solvability of wax pattern material.The present invention
It is preferred that the organic solvent that toxicity is low, stability is high, acquisition is easy, solvability is strong, cheap prepares mixed solvent.
Compared with prior art, the present invention has advantages below and beneficial effect：
The present invention is using organic mixed solvent prepared by alcohol organic solvent, alcohols polymer organic solvent and vegetable oil
3D printing sample is soaked, can directly dissolve the wax remained in 3D printing sample, it is ensured that thoroughly removes the base of wax pattern material
This requirement；Used plant oil density is low and boiling point is high, and it is covered in the upper strata of solution, can efficiently reduce other solvents
Volatilization, pollution is reduced, keep the solvability of mixed solvent；The inventive method is low to environmental requirement, simple to operate, cost is low,
Efficiency high, and size, structure, surface property of resin molding material etc. are not damaged, it is directed to suitable for laboratory or factory
The removing aftertreatment technology of wax pattern material, the 3D printing in particular by wax pattern backing material post-process link.
