Description
Technical field
Present invention relates in general to 3D printing technique fields.More particularly it relates to have elastic and low temperature to beat
Print the 3D printing based on FDM elastic low temperature nylon material and its technology of preparing of performance.
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 3D (three-dimensional) printing technique based on FDM is Layered manufacturing, successively superposition.Pass through design one
Or the ready-made 3D model of modes such as scanning is cut into unlimited number of section according to a certain reference axis, then printing in layer
Carry out and be stacked by original position the three-dimensional model for forming an entity together, 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).Wherein nylon is the maximum printing raw material of current dosage.
Nylon (PA) has very strong vitality, essentially consists in its modified realization as most important kind maximum in engineering plastics
The requirement high performance to product of the industries itself such as high performance, followed by automobile, electric appliance, telecommunication, electronics, machinery is more and more stronger
Strong, related industry rapid development promotes the process of engineering plastics high performance, plays an increasingly important role it.
With flourishing for the industry such as domestic automobile electric and electronic, requirement of the people to material is higher and higher, modified engineered plastic
Demand will be substantially increased.
FDM (Fused Deposition Modeling) technique is Fused Deposition Modeling (or melted extrusion modeling molding)
Technique was succeeded in developing by American scholar Scott Crump in 1988, was one of 3D printing suitable for three-dimensional printer
Technique.The material of FDM is usually thermoplastic material, such as wax, ABS, nylon, and with filiform feed, feed is heated in spray head
Fusing.Spray head is moved along part section profile and filling track, while the material of fusing being squeezed out, material quick solidification, and with
The condensation of materials of 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
It is alterable to content, various resins are made.Preliminary test shows that ABS plastic is applicable and makees 3D printing material.ABS plastic is applicable in
There is the printing device of heating device in bottom plate, it is printable relatively strong to printing intensity requirement and need the mould of subsequent processing
Type, for example, dyeing, polishing, plating etc., are suitble to beat small-sized spare and accessory parts etc..
Another material for being suitable for 3D printing is nylon material.Due to the limitation of current 3D printing technique, when general
When logical nylon material is used for 3D printing, print temperature is typically in the range of about 250~290 DEG C.Due to big portion in the market
Point 3D printer die heating temperature be up to 270 DEG C and cannot 3D printing at high temperature for a long time, and common nylon is being beaten
The alice being easy to appear in the process, warpage issues are printed, therefore limits its use in 3D printing technique, thus being applied to
It is unfavorable for the promotion and application of 3D printing technique when 3D printing.
In the prior art, when selecting common elastic material to be used for 3D printing, since elastic material wire rod is soft,
The problems such as blanking is easy to appear during FDM 3D printing to have some setbacks, prints difficult molding, and elastic material and to FDM 3D
Printer has higher selectivity, and therefore, general common elastic material is also unfavorable for 3D printing skill when being applied to 3D printing
The popularization and application of art.
Therefore, with the development and variation of 3D technology and application, it is badly in need of being directed to 3D printing nylon material in this field
Material provides improvement, to provide the improved nylon material for being more applicable for 3D printing practice, overcomes the above skill in the prior art
Art defect and other technical problems.
Present applicant is designed finally by continuous research, design, and after being studied sample repeatedly and being improved
The really novel elastic low temperature nylon material that can be used for FDM 3D printing of tool innovative value and application value.
Included information in this background technology part of specification of the invention, including any ginseng cited herein
Examine document and its any description or discussion, merely for Technical Reference purpose and be included, and be not considered as that will limit
The theme of the scope of the invention processed.
