Abstract
The invention discloses a 3D printing method for attaching a metallic material to the surface of a plastic piece. According to the technical scheme, plastic powder and metallic powder are adopted as printing materials of a product component simultaneously for 3D printing, and consequently, the component is internally made of plastic, the plastic part of the component mainly bears force and plays a supporting role, and the outer surface of the component is made of metal, so that the component has performance such as electricity conduction like some metals. An all-metal 3D printing technology is not mature at present, and during printing, the process is complicated, high energy such as electron beams is required, and the cost is high; however, 3D printing for plastic materials is easy to realize. By adopting the 3D printing method, both the force-bearing and supporting purposes and functionality of the component are achieved, and remarkable economic overall performance is realized.
Description
Technical field:
The present invention relates to a kind of 3D and print production method, especially produce inner for working of plastics top layer be the part of metal.
Background technology:
3 D-printing (Three Dimensional Printing, 3 DP) be a kind of rapid shaping technique that Massachusetts Institute Technology (MIT) invented in the 90's of 20th century, precisely, it should be increment manufacture (Additive Manufacturing, AM) technology.At the beginning of ideas put forward, just set up and can make any structure (Any-composition), any material (Any-material) and any geometry (Any-geometry) vision in kind.The similar ink-jet printer of operation principle of 3DP, but ejection is not ink, but binding agent, liquid wax, plastics or resin.Different according to the material of ejection, binding agent printing can be divided into, molten wax prints and molten plastic applies (FDM).Printhead can be changed into laser head, laser sintered (SLS), light-cured resin (SLA) and lf (SLM) also can be considered as the special case of 3 D-printing, therefore 3 D-printing one word of broad sense contains most of increment layered manufacturing technology, from macroscopically carrying out System Thinking, so that the public is to the understanding of new technology.3 D-printing is both completely different from the cutting working method removing excess stock from blank, also with by mould forges and presses, punching press, that casting and injection etc. force the technique of material forming far apart to have is different, is a kind of " increment " forming technique.Concrete forming process is, according to three-dimensional CAD model, after format conversion, carries out hierarchy slicing to part, obtains the two-dimensional contour shape of each layer cross section.According to these contour shapes, binding agent from level to level or heat-fusible materials is optionally sprayed with injection source, or optionally solidify liquid photosensitive resin from level to level with laser beam, or sintering dusty material from level to level, form the face profile shape of each layer cross section two dimension, and then be superimposed as 3 D stereo part from level to level.
Up till now, increment layered manufacturing technology has had huge progress, and increment layered manufacturing is not only confined to make prototype, can also produce available functional product; Not only can manufacture plastic product, can also metal product be manufactured; Not only can be used for Aero-Space, be also about to enter huge numbers of families; Not only can make modern art product, also can be used to high emulation copy antique; Not only can manufacture external things, can also body implant be manufactured, even human organ; Not only can manufacture articles for use, can also build a house, make cake and beefsteak; A kind of there is infinitely possible multipurpose technology, its prospect is extremely gorgeous, attracted numerous designers, engineer, amateur and investor to participate, become the blasting fuse that may cause the new industrial revolution, various countries' TV media and periodicals and magazines are reported one after another.The appearance of this climax is except unique potential advantages of 3 D-printing, also because the cost breakthrough that in recent years obtains and material are broken through and the sharply expansion of application, meanwhile breed with start dimly visible make new advances commercial affairs, production model and new life style.Some futurist thinks, its effect can match in excellence or beauty with computer and internet.
The technology using 3D to print all-metal goods can't extensively be popularized till now for various reasons, the equipment price being printing metal is on the one hand very expensive, the X series 1000R metal increasing material manufacturing system of such as Concept Laser company and the price of metal material 3D printer in Europe are up to 1,400,000 Euros, this cost is not that general metal parts can bear, in addition, special metallic print material is also very expensive.Carry out the specific product of the incompatible manufacture of specific group by the ripe also technology and equipment of extensive use of prior art and have certain necessity.
Summary of the invention:
The present invention is a kind of 3D Method of printing at plastic part surface adhesion metal material, its technical scheme is that a product parts uses molding powder and metal powder to carry out 3D printing as printing raw material simultaneously, final formation inside parts is that plastics are formed, plastics are as the main stressed support of part, part extexine is made up of metal, thus the performance of part is had picture conduction that some metal just can have and so on.
The plastics of nexine and the metal on top layer print according to the step section figure of 3D simultaneously and carry out, and the structure that plastics are formed is stressed mainly as support, and the master metal on top layer will exercise the performance that the metals such as conduction just have.
Some to intensity and force request be not very high metal parts can by this method fast, low cost prints.
Plastics also as the attached bed of metal powder, are convenient to the attachment of metal powder, make metal powder not need to melt or sinter just to form one.
Beneficial effect:
Present all-metal 3D printing technique is also immature, prints not only complex process but also need the high-energy source of electron beam one class, cost intensive, but prints the 3D of plastic material and be then easy to realize.Part stress can be realized by this method to support and function performance gets both, and there is good economic combination property.
Detailed description of the invention:
For better the present invention being described, be convenient to understand technical scheme of the present invention, typical but non-limiting embodiment of the present invention is as follows.
By the tomograph of pre-manufactured support input 3D printing device computer system, presetting only surperficial one deck is that metal dust prints.
Work according to the plastic powders discharge head of three-dimensional step section figure, 3D printing device and metal dust discharge head simultaneously.
After completing the printing of one deck, carry out the printing of lower one deck successively, can both well merge between the plastics of every layer, have certain stressed support, the metal powder of superficial layer, owing to being attached on plastics, also can form unified metal compaction layer.
Final formation inside parts is that plastics are formed, and plastics are as the main stressed support of part, and part extexine is made up of metal, thus the performance of part is had picture conduction that some metal just can have and so on.
Applicant states, above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
