Description
Technical field
Present invention relates in general to 3D printing technique fields.More particularly it relates to FDM 3D printing new A BS
Material and its production technology.
Background technique
3D printing technique is also known as layered manufacturing technology, is a kind of emerging technology of rapid shaping field, it is one kind with number
Based on word model file, with adhesive materials such as powdery metal or plastics, carry out structure by layer-by-layer printing
The technology of body.Basic principle is layered manufacturing, increases material successively to generate the technology of 3D solid.Currently, 3D printing technique
Product prototype, mold manufacture and the fields such as artistic creation, jewelry-making are applied primarily to, the essence that these tradition rely on is substituted
Fining-off technique.In addition, 3D printing technique is gradually applied to the fields such as medicine, bioengineering, building, clothes, aviation, for innovation
Wide space is opened up.
The basic principle of FDM 3D (three-dimensional) printing technique is Layered manufacturing, successively superposition.One by design or
The ready-made 3D models of modes such as scanning are cut into unlimited number of section according to a certain reference axis, then printing simultaneously in layer
The three-dimensional model for forming an entity together is stacked by original position, similar to the integral in higher mathematics.
The more common polymer material of FDM technology is one butadiene of acrylonitrile, one styrene copolymer currently on the market
(ABS), polylactic acid (PLA), nylon (PA) and polycarbonate (PC).
FDM (Fused Deposition Modeling) technique is Fused Deposition Modeling (FDM) technique, by American scholar
Scott Crump was succeeded in developing in 1988, was one of 3D printing technique suitable for three-dimensional printer.The material of FDM
Usually thermoplastic material, such as wax, ABS, nylon, with filiform feed, feed is heated fusing in spray head.Spray head is along part
Cross section profile and the movement of filling track, while the material of fusing being squeezed out, material quick solidification, and the condensation of materials with surrounding.
The advantages of FDM technology, is：(1) since heat melts extrusion nozzle system aufbauprinciple and easy to operate, maintenance cost is low,
System operational safety；(2) shaping speed is slow, and the product produced with fused deposition method, the scraper plate not needed in SLA adds again
This procedure of work；(3) the part prototype for using was moulding, is used directly for model casting；(4) arbitrarily complicated journey can be formed
The part of degree, being usually used in molding has the parts such as very complicated inner cavity, hole；(5) raw material in forming process without chemical change,
The buckling deformation of product is small.(6) utilization rate of raw materials is high, and material lifetime is long.
ABS plastic is the terpolymer of acrylonitrile (A), butadiene (B), styrene (S) three kinds of monomers, three kinds of monomer phases
Content can arbitrarily be changed, various resins are made.Preliminary test shows that ABS plastic is applicable and makees 3D printing material.ABS material
Production method mainly have emulsion graft polymerization method, emulsion graft polymerization-blending method, continuous bulk, bulk-suspension, emulsion graft polymerization-outstanding
Float glass process, emulsion graft polymerization-continuous bulk etc., wherein various production methods have its advantage and disadvantage, wherein most competitive method
For emulsion graft polymerization-ontology SAN blending method and continuous bulk, although it is simple with process flow, investment is smaller, pollution is few
Advantage, but the ABS material prepared is unable to reach the mechanical performance of higher gloss and material, such as bending strength is poor.
Moreover, ABS plastic, which is suitable for bottom plate, the printing device of heating device, can print to printing intensity requirement more by force with
And the model of subsequent processing is needed, for example, dyeing, polishing, plating etc., are suitble to beat small-sized spare and accessory parts etc..
However, the defects of there are warpage, alice, difficult moldings in ABS material print procedure currently on the market, FDM 3D is beaten
The effect is unsatisfactory for print, more lacks good post-processing grinding effect.Therefore, with the development and change of 3D technology and application
Change, is badly in need of providing improvement for ABS plastic in this field, to provide the improvement ABS material for being more applicable for 3D printing practice, gram
Take the above technological deficiency in the prior art and other technical problems.
Present applicant is designed finally by continuous research, design, and after being studied sample repeatedly and being improved
The really new A BS material that can be used for FDM 3D printing of tool innovative value and application value.
