Description
Technical field
The present invention relates to 3 D-printing field, especially a kind of 3 D-printing method, device and printer.
Background technique
FDM (Fused Deposition Modeling, Fused Deposition Modeling) technique be it is a kind of not against laser be used as at
The type energy, by various silk materials (such as ABS (Acrylonitrile butadiene Styrene copolymers, acrylic nitrile-butadiene
Diene-styrene copolymer), PC (Polycarbonate, polycarbonate) etc.) heating fusing and then accumulation molding method.
FDM print used in printed material be usually thermoplastic material, such as wax, ABS, PC, PA (Polyamide, nylon) etc., with silk
Shape feed.Material is heated fusing in spray head.Spray head is moved along part section profile and filling track, while by the material of fusing
Material squeezes out, and material solidifies rapidly, and bonds with the material of surrounding.Each synusia is accumulated on upper one layer, upper one
Layer plays the role of positioning and support to current layer.
This technique does not have to laser, and use, maintenance are simple, and cost is relatively low.With the part prototype of was moulding, can directly use
It is cast in paraffin.The prototype manufactured with ABS due to higher-strength product design, in terms of obtain extensively
Using.Develop PC, polycarbonate and acrylonitrile-butadiene-styrene copolymer and mixture PC/ABS, PMMA again in recent years
(Polymethyl Methacrylate, polymethyl methacrylate), the moulding material of the higher intensity such as PA, so that the technique
It is possible that directly manufacturing functional features.Since this technique has some remarkable advantages, the technological development is extremely rapid, at present
It is about 30% that FDM system, which has installed the share in rapid prototyping system in the whole world,.
FDM three-dimensional printer has the advantage that
1, do not use laser, maintenance is simple, at low cost: price be moulding process whether be suitable for one of 3 D-printing it is important
Factor.The three-dimensional printer for being chiefly used in conceptual design is of less demanding to prototyping accuracy and physicochemical characteristics, and cheap price is
Can it promote the deciding factor to come.
2, plastics silk material, cleaning, replacement are easy: compared with other are using the technique of powder and liquid material, silk material is more
Cleaning, be easily changed, save, will not in a device or be formed about powder or liquid pollution.
3, post-processing is simple: after only needing the time at a few minutes to a quarter of an hour to remove backing material, prototype be can be used.And
More SL (Stereo Lithography, Stereolithography), SLS (Selecting Laser are applied now
Sintering, selective laser sintering), 3DP (Three Dimensional Printing and Gluing, three-dimensional powder
Bonding) etc. techniques there is cleaning residual liquid and the step of powder, and curing process after needing to carry out needs additional auxiliary
Help equipment.These additional postprocessing working procedures first is that powder or liquid is be easy to cause to pollute, second is that increase several hours when
Between, it cannot be used at once after the completion of molding.
4, shaping speed is very fast: in general, FDM technique is relative to SL, SLS, and for 3DP technique, speed is slow
's.But it is directed to 3 D-printing application, also there is certain advantage.Firstly, SL, SLS, 3DP have interlayer process, (powdering/liquid is hung
It is flat), thus the multiple prototypes of their one-pass moldings be speed quickly, such as 3DP can accomplish one hour molding 25mm or so highly
Prototype.Three-dimensional printer molding space is small, and 1 to 2 prototype of primary at most molding, comparatively, their speed advantage is just
It is not very obvious.Secondly three-dimensional printer is not high to prototype intensity requirement, so FDM technique can be by reducing prototype compaction rate
Method improve shaping speed.By test, the model with certain design features, highest shaping speed can achieve 60
Cc/hour.Pass through software optimization and technological progress, it is contemplated that can achieve 200 ccs/hour of high speed.
But.The model compactness that the existing equipment using FDM technique prints is inadequate, and model is more coarse, not smart enough
It causes, the required precision in certain fields, such as the production of medical field small-sized diagnosis and treatment auxiliary device, human body replacement prosthesis, to model
It is higher, and these problems of FDM technique limit the development of its own.
