Description

Dual wavelength/binary laser 3D printing technology
Technical field
The present invention relates to a kind of dual wavelength/binary laser 3D printing technology, the laser suitable for two class unlike materials is beaten Print passes through two kinds of the setting different printing timing of optical maser wavelength or the position of laser printing head opposite piece, so that it may facilitate realization The three-dimensional printing of the intersecting of two kinds of unlike materials, multilayer covering or other complicated shapes.
Background technique
With the rapid development of laser 3D printing technology, become in preclinical medicine, clinical medicine and precision manufactureing often A kind of sclerous tissues joint/important manufacture means of organ/component, such as the reparation or displacement of human skeletal's defect, mouth Micro-component processing etc. in chamber dental implant, cardiovascular miniature bracket and precision machinery manufacture.But with the day of application direction Beneficial diversification and fining, also to laser 3D printing technology, more stringent requirements are proposed, such as sometimes for and meanwhile print it is several not Material together, the structure, and the diversified material with different soft and hard degree that manufacture interlaced or nested material, etc..
According to market survey it is found that the 90% of country's 3D laser printing technology sells the 90% of product dependent on foreign countries at present It is also imported product, especially for the clinical application laser printing apparatus of the components such as pelvis, joint prosthesis, dentistry, is produced from the country Product still have many blank.The optical maser wavelength that existing country's cavitas oris externa 3D laser printing apparatus uses is mostly 355nm or 405nm, It is respectively used to the printing of photosensitive resin class material or metal group material, every equipment is usually only with an optical maser wavelength.But with Continuous pursuit of the people to tooth-implanting durability and comfort level, it is sometimes desirable to adulterate some differences during tooth 3D printing Material or different piece use unlike material, or realize that unlike material is mutually nested etc..In the case, it is clear that wish to The flexible output of multiwavelength laser is enough provided, enable heating, cooling, perfusion, demoulding and etc. accomplish without any letup, have for complex shape The fine print capacity of shape.Dual wavelength of the present invention/binary laser 3D printing technology is proposed aiming at this demand.
Summary of the invention
The present invention relates to a kind of dual wavelength/binary laser 3D printing technology, the laser suitable for two class unlike materials is beaten Print passes through the printing timing of two kinds of difference optical maser wavelength print heads of setting or the position of laser printing head opposite piece, so that it may side Just the three-dimensional printing of the intersecting of two kinds of unlike materials, multilayer covering or other complicated shapes is realized.For example, the present invention proposes Dual wavelength/binary laser 3D printing technology involved in be 355nm pulsed ultraviolet laser and 405nm continuous wave laser, Wherein, 355nm pulsed ultraviolet laser is mainly used for the printing of metal class hard material, and 405nm continuous wave laser is mainly used for setting The direction of the printing of the materials such as lipid, the running parameter of two laser print heads and two laser printing head opposite pieces or Position can independently change, parallel or time-shared serial laser 3D printing while realization with this to two kinds of unlike materials.Two are swashed Optical printer head in the actual operation process, can be by changing position or the distance of two laser printing head opposite pieces, or changes The output timing of two lasers, or change by the angle of printing material carrying platform relative laser print head, it realizes to two kinds The arrangement mode of difference printing material, the printing for coating labyrinth in intersection and semiclosed workpiece.Operation is stated on the implementation When, it need to be by the cooperation in unison of the feed device of printing material.405nm continuous wave laser therein when in use, to improve it The laser printing flexibility for handling labyrinth can install laser output optical cable and matched all the way additional in laser printing head Printing material feed pipe, realize the labyrinth printing of small space or non-straight visual space.When use 405nm continuous wave laser When, to improve laser printing parameter with the adaptive adjustment capability of printing material quality status variation, it can also increase fiber optic temperature all the way The fibre-optical probe of sensor, the temperature sensor is in parallel with the laser output output end of optical cable, obtained in real time by printing material The profiling temperatures on periphery accurately adjust the output parameter of laser accordingly.
The advantages of dual wavelength/binary laser 3D printing technology, is mainly reflected in following several respects:
1, a 3D laser printer is provided simultaneously with two kinds of different optical maser wavelengths, pulse, continuous two kinds of different system laser Fan-out capability, for the laser printing technology of more existing single wavelength/system, it is easier to realize multiple to a variety of different types The fast laser printing shaping of condensation material.
2, a kind of optical fiber cable way of output and real time temperature fiber-optic monitoring are increased to 405nm continuous laser export head Means, more convenient realize are precisely controlled laser output parameters to the laser printing inside labyrinth, and by temperature change, Improve laser-quality.
Detailed description of the invention
The dual-wavelength laser 3D printing schematic device of Fig. 1 printing tooth
Specific embodiment
Dual wavelength/binary laser 3D printing technology specific embodiment is selected to print dual wavelength used in tooth It is described for laser 3D printing equipment.The device is made of control system 01, -16.
Specific implementation process substantially divides following several middle situations.
The first situation, the tooth printing step of single material.
The scan image for being replicated tooth is sent into control system 01, completes preset whole laser printing programmings. According to the print routine that control system 01 designs, the setting of output parameter, the metal that will be printed are carried out to 355nm laser 03 Powder material 02 inserts 355nm laser printing head 04, then prints titanium alloy dental cast 05 according to preset program；Simultaneously according to control The print routine that system 01 processed designs carries out the setting of output parameter, the liquid photosensitive tree that will be printed to 405nm laser 06 Rouge material 07 inserts 405nm laser printing head 08, then prints resin dental cast 09 according to preset program.If required It is only the tooth model of above-mentioned homogenous material, then this time laser printing task is completed.
Second situation, the finished product for needing to obtain are that titanium alloy dental cast 05 is inserted into resin dental cast 09.For this purpose, Pass through the print routine of 01 two kinds of materials of optimization design of control system, and the real-time inspection and control injected volume in print procedure first 10, to guarantee that two kinds of materials can print simultaneously or by Program alternation；According to situation of change (image, temperature of Real-time Monitoring Data Deng) and preset scheme, titanium alloy material is filled into 11 in resin dental cast in due course, the printing of whole tooth is completed after cooling 12 Program 13；The material 14 for carrying out launching colouring again completes colouring process 15, and the final outside that obtains is resin material, and inside is gold Belong to the tooth finished product 16 of material.
Above-mentioned apparatus can carry out 3D printing with two kinds of optical maser wavelengths simultaneously, and sclerous tissues and the compound of soft tissue are beaten in realization Print, meets different application demand.
