Description
Technical field
The present invention relates to one kind to be used for three dimensional printing（3DP）The preparation method of technique rapid shaping powder body material, belongs to fast
The Material Field of rapid-result type, more particularly to a kind of preparation method for three-dimensional printing art molding of gypsum powder body material and should
With.
Background technology
Gypsum is monoclinic system mineral, is that main chemical compositions are calcium sulfate（CaSO4）Hydrate.Usually white,
Colourless, colourless transparent crystal is referred to as selenite, sometimes because impure into grey, pale yellow, the shallow color such as brown.Streak white.It is transparent.Glass
Glass gloss, cleavage surface pearly luster, fibrous agrregate silky luster.Relative density 2.3.Land plaster be five big gel rubber materials it
One, occupied an important position in national economy, be widely used in building, building materials, industrial mould and artistic model, chemical industry and
Numerous application fields such as agricultural, food processing and medical beauty, are a kind of important industrial raw materials.For special industrial mould
Tool and artistic model have the advantages that formed precision is high, and cost is low, and speed is fast by 3D printing shaping.
3D printing is that the technology that material successively accumulation molding is three-dimensional objects is also known as by modelling and printing device
Make increasing material manufacturing.Many forward position necks such as digital modeling, Electromechanical Control, information technology, material science and chemistry have been merged in 3D printing
Domain, it is one of the core technology of " the third time industrial revolution ".3D printing technique is in Aero-Space, biological medicine, building, technique
The fields such as product manufacture are progressively widened, and the advantage such as its is convenient and swift, raising stock utilization constantly shows, and constantly promotes conventionally manufactured
The transition and upgrade of industry.
3D printing material is the material base of 3D printing, decides the wide usage of 3D printing, and restricting current 3D printing
The bottleneck of development.The species of 3D printing material is from initial high polymer material（ABS, PLA, PC, PVC, photosensitive resin）Expand
To metal（Various alloys, applied to high-end fields such as Aero-Space, medical treatment）, ceramics（Various inorganic non-metallic materials）Deng.Root
According to forming principle, 3D printing is defined as powder shaped, thread, lamellar, liquid, the different 3D of their own adaptation with material
Printing type.3D printing powder body material is applicable three-dimensional printing art（3DP）And selective laser sintering（SLS）, at present on 3D
The preparation method of printing powder body material also has relevant report, and Chinese patent 201510125390X discloses a kind of 3D printing dioxy
Change the preparation method of the body formed material of zirconium powder；Chinese patent 2015101260246 discloses a kind of 3D printing rapid shaping zirconium aluminium
The preparation of ceramic powder material, because inorganic non-metallic material has high intensity, high rigidity, high temperature resistant, low-density, chemistry steady
The qualitative excellent specific property such as good, corrosion-resistant, is widely used, it is in 3D printing field in industries such as Aero-Space, automobile, biologies
Demand can rapidly increase, therefore, selective laser sintering 3D printing inorganic non-metallic powder body material realizes that commercialization has
Particularly significant meaning and wide market.
Three dimensional printing（3DP）Technique, it is exactly the 3D printing of today, is Massachusetts Institute Technology Emanual Sachs etc.
What people developed.E.M.Sachs applied for 3DP in 1989（Three-Dimensional Printing）Patent, the patent are
One of core patent of non-shaped material droplet injection shaping category.3DP techniques are similar with SLS techniques, using dusty material into
Shape, such as ceramic powders, metal dust.Except that material powder is not connected by sintering, but pass through shower nozzle
Use bonding agent（Such as silica gel）Part is cut into " printing " on material powder.The part strength being bonded with bonding agent is relatively low, also
Must post processing.Specific embodiment is as follows：After last layer bonds, moulding cylinder declines a distance（Equal to thickness：0.013
~0.1mm）, rise a height for powder cylinder, if releasing dry powder, and moulding cylinder shifted onto by powder-laying roller, pave and be compacted.Shower nozzle
Under the control of the computer, by the formed data of next construction section, selectively jet binder builds aspect.Powder-laying roller powdering
Shi Duoyu powder is collected by powder collection device.Such powder feeding again and again, powdering and jet binder, are finally completed one three
Tie up the bonding of powder.Be not dry powder by the place of jet binder, played a supportive role in forming process, and shaping terminate after,
It is easier to remove.But this moulding process also has certain limitation, and the dosage of adhesive is big, bad control, adhesive holds
Easily block shower nozzle.
The present invention to gypsum powder body material by being granulated, by high molecular adhesive coating to granulation gypsum powder body material
Expect surface, gypsum powder body material directly can be molded using 3DP after obtained coating.It need not be sprayed in forming process gluing
Agent, it is only necessary to spray a small amount of solvent.Advantage is that adhesive dosage greatly reduces, and environment is reduced during subsequent calcination
Pollution, the quality of product are high.Powder body material uniform particle sizes prepared by the technique of the application, sphericity is high, good fluidity, is adapted to
The 3D printing of 3DP techniques is molded.In addition, the method that this patent provides is simple, cost is low.
