Description
Technical field：
The present invention relates to the preparation method of three-dimensional objects and its equipment technical field, a kind of beating for 3D products is refered in particular to
Impression method and for the 3D printer in this method, and the printhead in the 3D printer.
Background technology：
3D printer obtains development at full speed for several years at this, and existing 3D printer is before work firstly the need of utilization
Computer is modeled, and " section " for being then layered the threedimensional model built up is handled, then from lower
On successively " print " every layer of section, so as to ultimately form and institute's established model identical 3D products.According to this
Principle, current 3D printing technique mainly includes following two, SLA stereolithography apparatus mode and hot melt
Material spraying printing type.Both 3D printing techniques will be introduced below.
The principle that stereolithography apparatus mode makes 3D products is first, to be gone out by CAD design three-dimensional real
Body Model, slicing treatment is carried out using discrete program by model, designs scanning pattern, the data of generation will be accurate
Control the motion of laser scanner and lifting platform；Secondly, the scanner that laser beam is controlled by numerical control device,
Liquid photosensitive resin surface is irradiated to by the scanning pattern of design, consolidates one layer of resin in the specific region of surface
After change, after one layer of completion of processing, a section of part is just generated；Then, lifting platform declines a spacing
From, another layer of liquid resin is covered on cured layer, then second layer scanning is carried out, the second cured layer glues securely
Knot is so formed by stacking 3 D workpiece prototype, finally, by prototype from resin from level to level on previous cured layer
After taking-up, finally solidified, then through polishing, plating, spray painting or coloring treatment be desired product.
SLA is mainly for the manufacture of multiple kinds of molds, model etc.；Can also in the feed by adding other compositions,
The wax-pattern in precision-investment casting is replaced with SLA prototype models.SLA forming speed is very fast, and precision is higher,
But due to producing contraction in resin curing process, inevitably result from stress or cause deformation.Therefore develop
It is its development trend to shrink the high light-sensitive material of small, quick solidifying, intensity.
The principle of another hot melt material spraying printing weaving is similar with traditional ink-jet printer principle, and institute is different
, " ink " used in this 3D printer is a kind of hot melt material, such as hot melt wax, PUR.

With reference to shown in Fig. 5,6, illustrate the Method of printing of the 3D products of the present invention, this method passes through 3D printing
The printhead of machine successively spray material layer, and after the printing of every layer of material is finished, pass through what is set on printhead
Solidify light head and illumination curing is carried out to the designated area in the material layer of every layer of printing, by constantly superposition,
Finally by solvent by uncured region soluble, remaining solidification object is exactly required 3D products.
Still according to current 3D printing technique before printing 3D products, it is modeled by computer, and will
The 3D products of printing are needed to carry out layering tangent plane processing, and the tangent plane of every layer of layer-by-layer preparation.Wherein every layer tangent plane
Height H be default, H numerical value is generally 0.05-0.5mm, and specific numerical value is according to made 3D
Depending on Product Precision, usual tangent plane is more (H numerical value is smaller, and made 3D Product Precisions are higher), then
Constantly tangent plane is overlapped to form the 3D products to be made from bottom to top, comprised the following steps that：
The first step, first is sprayed by the printhead 1 of 3D printer 100 on the print platform 2 of printer
Layer of material 51.During by 11 spraying raw material of nozzle, and the position of printhead 1 need not be accurately controlled,
Because the raw material of printing uses the resin of gel state, this raw material has certain mobility in itself, as long as
The area of print area is set, then because the height H of every layer of material is fixed, it is possible to accurate
Calculate the raw material total amount required for every layer of material, so just can be with by the raw material extrusion capacity of control container 3
It is accurately controlled the height of every layer material.For example, raw material dosage of the setting per layer material is V.
Second step, after the completion of the spraying of the first layer of material 51, nozzle 11 is stopped, and does not continue to spraying
Raw material.Now the solidification light first 12 on printhead is started working, and it, which will launch, to be consolidated to raw material
The light of change.Printhead 1 will be moved in the driving of mechanical arm 4 in X/Y planes, to the first layer of material
Region in 51 residing for corresponding 3D products carries out illumination curing, is formed and is cut by the first layer of printing 3D products
Face 61, i.e., by the orlop tangent plane of printing 3D products.
According to noted earlier, because the raw material of printing uses the resin of gel state, this raw material has in itself
Certain mobility, although the mobility of this material is limited, but if be not any limitation as, this raw material is still
It will certainly will thus cause the height of the first sprayed layer of material 51 with slow speed to around spreading
Diminish, while being constantly superimposed if over the material layer subsequently sprayed, this mobility is with the increase of gravity
Increase, effective stack layer can not be formed by eventually resulting in.So, a maximum technical characterstic of the present invention is just
It is to need to form one " container ", at least by the region residing for 3D products around surrounding, to ensure the original of spraying
Material will not spread because of gravity to surrounding.The scheme that the present invention is used is exactly：The corresponding 3D in material layer
When region residing for product carries out illumination curing, while solidify a framework region simultaneously in the material layer,
The framework region is by the region residing for described 3D products around encirclement.With reference to the first layer of material 51, when right
When region residing for corresponding 3D products carries out illumination curing in first layer of material 51, first should first this
Layer of material 51 outer peripheral areas of layer solidify a framework region, as shown in Figure 5.In the first layer of material 51
The region at close edge have cured first layer framework layer 71 by solidifying light first 12.So due to first layer frame
The presence of body layer 71, the raw material being limited in the first layer framework layer 71 just spreads without normal direction surrounding, so that
It ensure that the accurate of the height of first layer tangent plane 61.
3rd step, after the solidification of first layer tangent plane 61 is completed, solidification light first 12 is stopped, and now sprays
Mouth 11 restarts work, sprays the second layer of material 52.Second layer of material 52 and the second layer of material
It is identical, and overlap, the consumption of material is also just the same.Likewise, the second layer of material 52 is sprayed
After the completion of, solidification light first 12 is started working, first in the second layer of material 52, positioned at first layer framework
The upper area of layer 71, solidify to form second layer framework layer 72,.Then, in the corresponding 3D productions in intermediate region
Region residing for product carries out illumination curing, is formed by the second layer tangent plane 62 of printing 3D products.
Then, according to section model set in advance, the step is constantly repeated, until completing all material layer
Spraying, and complete the solidification of all framework layers and the solidification of product tangent plane layer.Wherein first layer framework layer, the
Two layers of framework layer ... constantly superposition solidify to form an entirety --- framework 7.First layer tangent plane 61, the second layer
Tangent plane 62 ... constantly ground connection solidify to form an entirety --- 3D products 6.
Now, the material layer outside framework 7 may be caved in already due to the mobility of raw material, so to four
Zhou Yanchong spreads, but the material layer inside framework 7 is still the stacking according to default requirement successively.Wherein
First layer tangent plane 61, second layer tangent plane 62, until the tangent plane of top should be fully cured, form 3D products
6.And material uncured in framework 7 is produced still in the state of gel state, or semi-solid preparation, and by 3D
Product 6 flood.Next step is accomplished by separating 3D products 6 from the raw material of these gels or semi-solid preparation shape
Out.
4th step, all material in whole framework 7 is put into solvent, or is directly rinsed by solvent
In framework 7.By solvent by region soluble uncured in material layer in whole framework 7, residue is not dissolved
Solidification it is overall be exactly printed 3D products 6.
It is corresponding for example with UV resins because resin 7 used in the present invention is a kind of light-cured resin
Solidification light first 12, which can be produced, can solidify the light of printing raw material.It is cured the UV that light first 12 is produced
After light irradiation, can occur physical and chemical changes rapidly in the short period of time, and then crosslinking curing is oligomeric
Thing.If so just can be by uncured dissolution of raw material using related solvent, and the original being cured
It can not be dissolved by the solvent during material, finally just obtain the framework 7 of auxiliary and final 3D productions during a printing
Product 6.
In summary, this device that the present invention is used, its is simple in construction, and it is using solidifying that it, which prints 3D products,
The mobility of glue-type resin in itself, so need not be set using heating, it is not necessary to carry out heating melting to raw material.
Meanwhile, in order to overcome the mobility of raw material, attached middle school's framework 7, is limited raw material when adding a printing
System, to ensure the present invention when spraying is per layer material, height value is accurate.The present invention can not only make precision compared with
High three-dimensional objects, and relative to the printing type of traditional PUR, its cost of manufacture is lower, and precision is more
It is good.
Certainly, the specific embodiment of the present invention is the foregoing is only, not the scope of the present invention is limited,
All equivalent change or modifications done according to construction, feature and principle described in scope of the present invention patent, all should be wrapped
Include in scope of the present invention patent.
