Description
Technical field
The present invention relates to a kind of oral cavity model 3 D-printing method, and in particular to a kind of Diagnosis
Model is without support 3 D-printing method.
Background technology
With the development of oral medical digitizing technique and intraoral 3-D scanning technology, intraoral three-dimensional
Scanning directly obtains patient's denture, gum three dimensional surface data, you can directly obtain the mouth of patient
Chamber 3-D graphic information, i.e. dentognathic model 3 d scan data.
Compared with traditional impression gypsum recording method, the digital mould of patient obtained using 3-D scanning
Type, hard disk can be directly stored in, it is necessary to when 3D printing at any time use, without store it is substantial amounts of
Mock-up, while saving space, embodies the theory of energy-conserving and environment-protective.
But when printer model, if using physical print, not only wasting printed material,
And it is extremely inefficient, it is unfavorable for clinical oral high efficiency, allegro medical environment.And use
When hollow printing, due to the complexity of oral cavity denture gingival surface form, it is difficult to improve ground
Addition printing support, also needs to consume the substantial amounts of time even if with the addition of complete support, after printing
Support is removed, and the resolution detail of dental surface may be influenceed.
The content of the invention
It is an object of the invention to provide a kind of Diagnosis model without support 3 D-printing method, energy
By the targetedly optimal design-aside of the precise controlling parameter to print procedure, Diagnosis is realized
The high efficiency of model is without support 3D printing, the nothing suitable for the various model 3 d scan datas of the department of stomatology
Support, high efficiency three-dimensional printing-forming.
In order to achieve the above object, the present invention has following technical scheme：
A kind of Diagnosis model of the present invention has following steps without support 3 D-printing method：
1) the intraoral denture of patient and gum are directly scanned with intraoral spatial digitizer, or
The plaster cast of patient is scanned with dentognathic model spatial digitizer, denture gum STL data are obtained,
Import three-dimensional data software for editing；
2) to model addition and the conjunction of | tooth in three-dimensional data software for editing | plane approximation is parallel
Base plane, and the axial plane vertical with base plane, are one with the suture of mathematical model surface
Watertightness block mold；
3) the mathematical model STL data with base are imported into 3 D-printing layered code editor
In software, make mathematical model median sagittal plane vertical with print platform plane, labial teeth is upward；
4) angle of inclination of the adjustment model on median sagittal plane, makes model need type list
Level interval in the data Z-direction of face between continuous two layers is less than the 1/2 of printing thickness；
5) control material shower nozzle is printed along data surface spiral, makes all surface print procedure
In shower nozzle empty driving and jump do not occur；
6) setting model wall thickness is that shower nozzle single is fed the optimum width that can be printed；
7) the internal filling rate of printing is set as zero；
8) generation layering print code, is input to the 3 D-printing control software of printer, i.e.,
Printing can be started.
The advantage of the invention is that：Can be targeted by the precise controlling parameter to print procedure
Optimal design-aside, the high efficiency of Diagnosis model is realized without support 3D printing, suitable for oral cavity
The various model 3 d scan datas of section without support, high efficiency three-dimensional printing-forming.
