Abstract
The invention discloses a kind of 3D printing method of medical model, comprise the following steps：A, obtain three-dimensional modeling data, model is imported into magics softwares by the stl file provided by client to carry out the positions of all mold elements and fix, and outputs it the file of STL forms, then the modification for carrying out model is imported into 3Dmax softwares with cutting；B, foundation model organ present situation, the maximum boundary of each organ three-dimensional coordinate carries out cutting line setting along after making a variation, and the part that cutting is separated is exported into stl file respectively；C, the stl file kept is deposited into Cura softwares, the mimeograph documents of output gcode forms start printing.The present invention can solve the problem that the deficiencies in the prior art, improve the precision of 3D printing organ model.
Description
Technical field
The present invention relates to 3D printing technique field, the 3D printing method of especially a kind of medical model.
Background technology
Human organ model is the Main Means for medical teaching, clinical treatment auxiliary.Pass through mould process system at present
The manikin made is unable to the flowing of simulated organ internal blood, blood pressure, Temperature changing, i.e., current manikin is to see
Examine type, rather than functional form.Due to this inherent characteristic of prior art, user can only observe the dissection knot of human organ
Structure, the manikin for being difficult to use current observation type carries out dissection operation, and dissection operability and validity are had a greatly reduced quality,；Moreover,
Clinician needs to carry out sufficient operation plan and prediction scheme before surgery when running into intractable case, and the human body of observation type at present
Model perfect can not embody anatomical position relation between organ internal pipeline, can not simulate pulse, blood pressure and Temperature changing, nothing
Method is used for carrying out simulation operation, and the defect of existing die type manikin manufacturing process limits the function of manikin and answered
With.3D printing technique is a kind of printing technique that fast development in recent years is got up.Its major advantage is
The specific shape object of realization is easily printed, and can just be passed through without proembryo and model directly according to computer graphics data
The mode of superposition material produces variously-shaped object, simplifies the fabrication schedule of product, realizes technological break-through, shortens
Product development cycle, improves efficiency and reduces cost.
But, the model error that existing 3D printing technique is produced is in 1mm or so, it is impossible to accurately reflect true device
The internal structure of official.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of 3D printing method of medical model, prior art can solve the problem that
Deficiency, improve the precision of 3D printing organ model.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of 3D printing method of medical model, comprises the following steps：
Model imported into magics softwares and carried out by A, acquisition three-dimensional modeling data, the stl file provided by client
The position of all mold elements is fixed, output it the file of STL forms, then is imported into 3Dmax softwares and carried out model and repair
Change with cutting；
B, foundation model organ present situation, the maximum boundary of each organ three-dimensional coordinate carries out cutting line setting along after making a variation, will
The part that cutting is separated exports stl file respectively；
C, the stl file kept is deposited into Cura softwares, the mimeograph documents of output gcode forms start printing.
Preferably, in step B, when each cutting plane is set, cutting plane passes through the phase of each internal organs outer wall and sustainer, vein
Cross surface central point.
Preferably, in step C, printing comprises the following steps,
C1, all models are stored into SD card；
C2, will PLA printed materials send into printer in start printing；
C3, printing take out all models after finishing, the residue polishing for support of being dismantled after model is printed using sand paper
Light；
C4, the model for completing all polishings take out progress splicing and are completed.
Preferably, in step C2, the parameter of printer is set before printing, printing thickness is 0.1mm, print speed
60mm/s, adds bottom plate, and support is filled with 20%.
Preferably, in step C4, organosilicon note sealing is pressed 10:1 proportions are good, are filled into model,
Wait is fully cured for 24 hours, the model being cured.
The beneficial effect brought using above-mentioned technical proposal is：The model that the present invention makes can guarantee that model essence
Degree is determined between 0.1-0.2 millimeters, and surface flatness is high, being capable of high-precision reduction sufferer internal organ and cranium intracerebral lesion
Truth afterwards.The model data worked it out with this technology is more accurate, true to nature.More accurately prediction scheme is provided for operation prediction scheme
Model, and significantly shorten operating time, reduce the occurrence probability of postoperative complication.The manufacturing speed of the preparation method of the present invention
It hurry up, the model toughness produced is strong, and the holding time is long.
