Mould schematic top plan view.Represent for clarity.Below
To explain by taking the multiple sizes of synchronous making, artificial tooth of different sizes as an example, but three-dimensionally shaped board 100
Application be not limited with the making of multiple sizes, artificial tooth of different sizes.For example, utilizing
Before three-dimensionally shaped board manufacturing artificial tooth, need first to stretch in the oral cavity of sufferer with three-dimensional scanner, with right
Multiple teeth that sufferer to be substituted are scanned, and wherein three-dimensional scanner is e.g. for being exposed to outside gingiva
Multiple coronas be scanned, with the three-dimensional point data that obtains multiple coronas, (corona i.e. the present embodiment is be intended to be made
The ceramic member of work).Then, by each pen three-dimensional point data loading reverse engineering software, such as 3-matic,
Imageware, PolyWorks, Rapidform or Geomagic, to be built by reverse engineering software
Structure goes out the three-dimensional digital model of each scanned corona.Specifically, aforementioned three-dimensional digital model can have
There are relative Internal periphery and outline, Internal periphery and outline are respectively divided into into multiple two dimensions and cut layer, with
To the two-dimentional track of the control motion of jet-printing head 122.
Fig. 2A and Fig. 3 is refer to, and makes control unit (not shown) layer institute be cut according to the two dimension of each corona right
The three-dimensional moving parallel structure constituted by two-dimentional TRAJECTORY CONTROL fixed support 121 and the connecting rod 123 answered, with
Drive shower nozzle 122 relative to microscope carrier 110 along the X-axis in space as shown in Figure 1, Y-axis and Z axis
Move, and heat-fusible materials are provided to microscope carrier 110 by jet-printing head 122, to divide on microscope carrier 110
Mould 10 is not printed.Specifically, mould 10 can have charging aperture 11, be connected with charging aperture 11
Multiple chamber 12a～12h and the multiple flash mouth 13a～13h being connected with these chambers 12a～12h.
Each chamber 12a～12h is consistent with the three-dimensional digital model of corresponding corona respectively, thus with different
Profile, volume.
In the present embodiment, mould 10 also has the first feeding-passage 14, multiple second feeding-passages
15a～15h and multiple flash passage 16a～16h, its middle charging aperture 11 by the first feeding-passage 13 with
Second feeding-passage 15a～15h is connected, and chamber 12a～12h passes through flash passage 16a～16h respectively
It is connected with flash mouth 13a～13h.
Then, mould 10 is delivered to along path P the lower section of material feeding unit 130 by microscope carrier 110, and
Filling head 132 is made in alignment with the charging aperture 11 of mould 10, then storage is pushed by piston type push rod 133
Moulding material 134 in cell body 131 so that the moulding material 134 of part is projected from filling head 132,
And chamber is injected separately into via charging aperture 11, the first feeding-passage 13 and the second feeding-passage 15a～15h
In room 12a～12h.Then, persistently by 134 injecting chamber 12a of moulding material～12h.Treat chamber
12a～12h is formed after material 134 fills up, and unnecessary moulding material 134 can be respectively via flash passage
16a～16h is flowed out from flash mouth 13a～13h.In other words, when moulding material 134 is from flash mouth 13a～13h
When flowing out mould 10, represent chamber 12a～12h and be formed material 134 respectively and filled up.So far,
Just the action of material feeding can be temporarily ceased.
In the present embodiment, the sectional area of each second feeding-passage 15a～15h is logical more than corresponding flash
The sectional area of road 16a～16h.Based on Bernoulli law (Bernoulli's law), it is so designed that and will be helpful to carry
The speed of material feeding and filler is risen, and the speed of flash can be more than the speed of material feeding.
Afterwards, Fig. 2 C are refer to, after moulding material 134 fills up chamber 12a～12h, by microscope carrier 110
Mould 10 is delivered in heating unit 140 along path P.As shown in figure 1, by 110 edge of microscope carrier
When mould 10 is delivered to heating unit 140 by path P, cover plate 142 can expose holding for heating furnace 141
Mouth 141b, makes microscope carrier 110 and mould thereon 10 send in furnace chamber 141a via opening 141b.
After mould 10 in microscope carrier 110 and thereon is sent in furnace chamber 141a, cover in out cover plate 142
Mouth 141b, to be heated to the moulding material 134 in chamber 12a～12h by heating furnace 141, to form
Multiple three-dimensional objects, such as different artificial tooth of multiple profiles, volume.Fig. 2 C illustrate out two of which three
Dimension object (such as artificial tooth) 21 and 22 is with signal.In another embodiment, the profile of the chamber of mould,
Volume can be identical each other, to produce identical three-dimensional object.
In sum, 3 D-printing board of the invention first can be produced with many of differently contoured, volume
The profile of the mould of individual chamber, wherein these chambers, volume respectively with multiple three-dimensional objects to be produced
Profile, volume are consistent.Afterwards, continue carry out injection moulding material in these chambers, heating be filled in this
The steps such as the moulding material of a little within the chambers, obtain the different three-dimensional article of multiple profiles, volume to make simultaneously
Part.In other words, 3 D-printing board of the invention not only operate simply, manufacturing man-hours it is shorter, without the need for throwing
Enter a large amount of manpowers, and can meet while making obtains multiple profiles, volume different three-dimensional object
Required precision and surface roughness.On the other hand, without the need for controlling processing come except material by computer numerical
In the case of, more it is avoided that the waste of material.
