Abstract
The present invention relates to 3D printing technique field, specifically disclose a kind of 3D printing method, the peripheral frame closed by solid state support file printing, for filling liquid backing material provides architecture basics, by introducing liquid support material, during the more complicated product model of printing internal cavity, without filling up solid state support material in cavity, the inner chamber of the common filling product model of support column and liquid support material being made up of solid state support material, after printing completes product model by this way, liquid support material can be poured out directly, space in cavity is larger, support column is also relative to be easier and model separation.In addition, the cost of liquid support material is usually less than the solid state support material of o photopolymerizable type, compared with prior art, liquid support material is introduced, consumables cost can also be reduced.
Description
Technical field
The present invention relates to 3D printing technique field, and in particular to a kind of 3D printing method.
Background technology
Objet Geometries companies are pioneer of the 3D printing technique field with o photopolymerizable injection of material technology, should
The 3D printer of company's production, generally carries out modelling by the way of o photopolymerizable material is sprayed on the table, wherein
O photopolymerizable material includes the cast material of the backing material and formation finished product model as support.What this kind of printing type was present
Defect is, when printing inside has the model of cavity, to be required to fill up backing material in cavity, if the chamber inside model
Body structure is complex, then after the completion of product printing, the backing material in cavity and model separation are existed into larger difficulty
Degree, needs to pay larger time and energy in separation process.
The content of the invention
The technical problem to be solved in the present invention is to solve to be beaten with the 3D of o photopolymerizable injection of material technology in the prior art
Watermark patterns exist model internal cavity structure it is complex in the case of, backing material and the more difficult technology of model separation lack
Fall into.
In order to solve the above-mentioned technical problem, the technical scheme that the present invention is provided is as follows：A kind of 3D printing method, its feature exists
In, during 3D printing at least will using three types printed material, respectively：Cast material, solid state support material and liquid
State backing material, wherein cast material and solid state support material use o photopolymerizable section bar material；Described 3D printing method includes
Following steps：
（1）The peripheral frame closed using solid state support file printing on the table；
（2）Solid state support file printing support base is used in region in enclosing for peripheral frame；
（3）Cast material printed product model is used on support base, in print procedure, the synchronous filling liquid fid in peripheral frame
Material, wherein there are multiple support columns the inner chamber of product model by solid state support file printing, except support in the inner chamber of product model
Filled by liquid support material in region outside post.
Further, the height of the peripheral frame gradually rises during printer model, and peripheral frame height all the time with mould
Type it is highly identical.
Further, in printed product model process, the cast material for being used can be various.
3D printing method of the invention, the peripheral frame closed by solid state support file printing is filling liquid backing material
There is provided architecture basics, by introducing liquid support material, during the more complicated product model of printing internal cavity, without
Solid state support material is filled up in cavity, the support column and the common filling product of liquid support material being made up of solid state support material
The inner chamber of model, after printing completes product model by this way, liquid support material can be poured out directly, the space in cavity
Larger, support column is also relative to be easier and model separation.
Brief description of the drawings
Fig. 1 is the schematic diagram with the present embodiment 3D printing method printed product model；
Fig. 2 is the partial schematic diagram of product model internal cavity.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of 3D printing method of the present embodiment, will at least use the printed material of three types during 3D printing,
Respectively：Cast material, solid state support material and liquid support material, wherein cast material and solid state support material are using photosensitive
Polymeric materials, and cast material can have various, support many file printings.
With reference to Fig. 1, the 3D printing method of the present embodiment is comprised the following steps：
（1）The peripheral frame 2 closed using solid state support file printing on workbench 1；
（2）Solid state support file printing support base 4 is used in region in enclosing for peripheral frame 2；
（3）Cast material printed product model 3 is used on support base 4, in print procedure, light is met in the synchronous filling in peripheral frame will not
The liquid support material of solidification.As shown in Fig. 2 wherein there are multiple branch the inner chamber of product model 3 by solid state support file printing
Filled by liquid support material 5 in dagger 6, the region in the inner chamber of product model in addition to support column.It should be noted that beating
During print, the height of peripheral frame 2 gradually rises, and the height of peripheral frame 2 is highly identical with model 3 all the time.
It should be noted that above-mentioned steps（1）、（2）、（3）The sequencing of printing, peripheral frame, solid state support are not represented
The support base and support column and product model of material composition are synchronous elevated in print procedure.
By the 3D printing method of the present embodiment, substantial amounts of sky is there is after product model is printed successfully, in mould impression
Gap, support column is more convenient and model separation.Compared with mould impression in the prior art fills up solid state support material, the later stage separates branch
Timbering material enhanced convenience, required manpower is less, and separation costs are lower.In addition, the cost of liquid support material is usually less than
The solid state support material of o photopolymerizable type, compared with prior art, introduces liquid support material, can also reduce consumables cost.
In a word, presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in the present invention
Spirit and principle within any modification, equivalent and the improvement made etc., should be included in protection scope of the present invention it
It is interior.
