Description
Technical field
It is more particularly to a kind of to be used in 3 D-printing mistake the present invention relates to a kind of 3 D-printing consumptive material and preparation method thereof
Shaping silk of the soft elastic part of three-dimensional body and preparation method thereof is built in journey.
Background technology
Three-dimensional printer, is a kind of mathematical model based on three-dimensional body, using powdery metal or plastic or other material, is led to
The equipment for constructing three-dimensional body after the mode successively printed.
Notification number for CN1216726C patent document background technology in describe it is a kind of in the form of filament to printing
The three-dimensional printer of head supply moulding material, referring to Fig. 1, three-dimensional printer 01 has printhead 011, feeding device 012, conduit
013 and objective table 014；Feeding device 012 has a supply disk 0121 for being wound with shaping silk 0123；Printhead 011 has
A pair of the feed rollers 0113 and 0114 driven by motor 0115, liquefier 0111 and the printing located at the lower end of liquefier 0111 are sprayed
Mouth 0112.Supply disk 0121 is installed in the rotating shaft 0122 of the supply disk mounting bracket of three-dimensional printer 01, so that by shaping silk
0123 is supplied to printhead 011.In use, shaping silk 0123 is pulled out from supply disk 0121, make to be straightened into
Type silk by the conduit 013 that is made up of the less material of frictional resistance, until by shaping silk be supplied to feed roller 0113 and
0114, under the driving of feed roller 0113 and 0114, shaping silk enters liquefier 0111, and shaping silk is passed through in liquefier 0111
The moulding material of molten condition is heated into, in the presence of subsequent forming silk thrust, extrudes and is deposited on from printing nozzle 0112
On the loading surface of objective table 014.The control unit of three-dimensional printer 01 is by controlling printhead 011 in the X-Y plane of level
It is mobile, while the Z axis movement of objective table 014 vertically is controlled, so as to print three-dimensional body layer by layer.
The hard shaping silk that existing shaping silk is mainly made up of the thermoplastic hard material such as ABS, PLA, PA, PC and PP, is used
In printing hard three-dimensional body；In addition, also having some soft shaping silks being made up of thermoplastic elastomer (s), for printing soft bullet
Property three-dimensional body.
For there is the three-dimensional body of soft elastic part and hard portions, it is necessary to make on same three-dimensional printer simultaneously
Printed with two kinds of shaping silks, but above-mentioned soft shaping silk and hard shaping silk can not be bonded one well after melting
Rise, it is difficult to print required three-dimensional body.In addition, existing soft shaping silk is too soft, its bending strength is not high enough, positioned at sending
First stage building silk 01231 between material roller and liquefier 0111 is bent under the thrust of material-feeding rolling wheels, it is difficult in liquefaction
" liquifier pump effect " is produced in device, it usually needs improve the heating-up temperature of liquefier, and by molten condition moulding material from
Body gravity and flow out printing nozzle, the not only discharge rate of uncontrollable moulding material, and molten condition relatively at higher temperature
Moulding material is unfavorable for the printing precision of soft elastic part in the cooling and solidifying after printing, reduction three-dimensional body.
