Description

3D prints people's bone model medical material and preparation method thereof

Technical field

The present invention relates to 3D printing shaping field of material technology, especially relate to a kind of 3D and print people's bone model medical material and preparation method thereof.

Background technology

3D prints (3D printing), the i.e. one of rapid shaping technique, and it is a kind of based on digital model file, uses powdery metal or plastics etc. can jointing material, is carried out the technology of constructed object by the mode successively printed.

3D printing technique, design a model as source with Computerized three-dimensional, discrete and the numerical control molding system by software hierarchy, utilize the mode such as laser beam, hot melt nozzle successively to be piled up by the exotic materialss such as metal-powder, ceramic powder, plastics, cell tissue to cohere, final superposition is shaping, produces entity products.Starting material are shaped by the mechanical workout such as mould, turnning and milling mode from traditional manufacture, cut with final production finished product different, 3D prints and 3D solid is become several two dimensional surfaces, producing by also successively superposing material processing, greatly reducing the complexity of manufacture.This Digitized manufacturing pattern does not need complicated technique, does not need huge lathe, does not need numerous manpowers, from computer graphics data, directly just can generate the part of any shape, make the manufacturing be able to extend to wider production crowd scope.

Along with the development of 3D printing technique, its range of application is more and more extensive, particularly in medical field.The medical use that 3D prints is a lot, mainly complicated orthopaedics and dental operation.The complexity of this body structure of human body often exceeds our imagination, sometimes surgeon, to the operation of some complexity, often can only carry out possible judgement by the Medical Imaging such as CT, nucleus magnetic resonance data, and then perform the operation, but sometimes, complexity exceeds the imagination, and success rate of operation is low.But 3D printing technique, can utilize existing medical image data, the patient model first printing a 3D out, by simulating on model, and then being determined feasible operation plan, can be provided the success ratio of operation to a great extent.

But restriction 3D prints the printed material that universal principal element is its costliness at present.Require that the precision printed is higher, the faster requirement to material of speed is also more different.The price of material from 700-800 unit per kilogram, to several thousand per kilograms not etc.So the cost of self machine of 3D printer not only will be reduced in the future development of 3D printer, also material cost must be reduced, although there has been now the 3D printer adopting terra alba as printed material on the market, the precision that it can be worked it out has been had a greatly reduced quality.

Summary of the invention

The object of the invention is to the defect overcoming prior art, provide a kind of 3D to print people bone model medical material and preparation method thereof, the physical components cost printed with it is low, and printing precision is high, cohesive strength and firmness higher; Its forming method is simple, and material source scope is wide.

The technical solution adopted for the present invention to solve the technical problems is: 3D prints people's bone model medical material, comprises the following component counted by weight:

Particularly, described terra alba fineness is 800 orders.In order to ensure to use the 3D moulding that 3D of the present invention printing people bone model medical material prints to have higher precision, the fineness of terra alba is more thin better.

Particularly, the epoxy equivalent (weight) of described oxyethane is the bisphenol A type epoxy resin of 600-1500.Because epoxy resin possesses good cohesive force, hardness, snappiness and the good wettability to gypsum, epoxy resin is used to bond to gypsum, make gypsum in the moulding of final 3D printing shaping by good bonding, and drastically increase adhesive fastness and the intensity of parts, there is the phenomenon of delamination hardly.

Particularly, described flow agent is the one in acrylate, polydimethylsiloxane and polyether polyester modified organic silicon oxygen alkane.Flow agent is mainly used for the surface tension of the gypsum material system reducing 3D printing shaping, improves epoxy resin to the wettability of gypsum surface.

Particularly, described toughner is the one in dibutyl phthalate, carboxyl liquid acrylonitrile butadiene rubber, thiorubber, polyethers and polysulfones.Toughner is mainly used for regulating the interaction force between printing system epoxy resin molecular chain, to improve the snappiness of the moulding of 3D printing shaping, improves its impact strength.

Particularly, described lubricant is the one in polyethylene wax, Poly Propylene Wax, polytetrafluoroethylmodified modified Poly Propylene Wax.

Particularly, described metal powder is the one of copper powder, aluminium powder and magnesium powder, and the particle diameter of metal powder particle is less than 800 orders.

3D prints the preparation method of people's bone model medical material, by above-mentioned formula by after predetermined proportion batching, put into mixing machine fully dispersed with stirring, melt extruded by twin screw extruder by the compound mixed, district's temperature of twin screw extruder controls: 160 ± 2 DEG C; Two district's temperature control: 165 ± 2 DEG C; Three district's temperature control: 170 ± 2 DEG C; Four district's temperature control: 165 ± 2 DEG C; Material after extruding is put into crusher for crushing, screening, and screening fineness is more than or equal to 200 object powder.

The invention has the beneficial effects as follows: 3D provided by the invention prints people's bone model medical material, and the physical components cost printed with it is low, and printing precision is high, cohesive strength and firmness higher; Can be used for printing the patient model of 3D, by simulating on model, and then determine feasible operation plan, the success ratio of operation can be provided to a great extent.

3D provided by the invention prints the preparation method of people's bone model medical material, and its forming method is simple, convenient operation, and material source scope is wide.
