Detailed description of the invention
Below, in conjunction with detailed description of the invention, the present invention is described further:
As Figure 1-3, a kind of 3D printer hopper, including hopper base plate 1, mould release membrance 2 and hopper pressing plate 3, mould release membrance 2 is fixedly mounted on hopper base plate 1, and described hopper pressing plate 3 is fixedly mounted on mould release membrance 2.
Offering the first opening 11 on hopper base plate 1, hopper pressing plate 3 offers second opening 31 corresponding with described first opening 11 position, size, the setting of the first opening 11 and the second opening 31 is beneficial to printing opacity, is also beneficial to adhesion and the solidification of photosensitive resin.
The base 33 of hopper base plate 1 is arranged with a groove 13 along the outward flange of the first opening 11, the lower surface of described hopper pressing plate 3 is provided with the boss 35 mated with groove 13, and the boss 35 of hopper base plate 1 and the groove 13 of hopper pressing plate 3 cooperate the rate of tension that can regulate mould release membrance 2 for ensureing mould release membrance 2 surface horizontal homogeneous.
Hopper base plate 1 offers bottom hole 12, sealing gasket 4 offers the sealing gasket through hole 41 corresponding with bottom hole 12, offering the pressing plate through hole 32 corresponding with sealing gasket through hole 41 on hopper pressing plate 3, hopper base plate 1, sealing gasket 4, hopper pressing plate 3 sequentially pass through pressing plate through hole 32, sealing gasket through hole 41, bottom hole 12 to achieve a fixed connection by securing member.
Hopper pressing plate 3 includes base 33 and framework 34; Framework 34 is located on the inwall of the second opening 31 of base 33 and projection goes out the upper surface of base 33, and this is in order to avoid photosensitive resin overflow is gone out.
Hopper base plate 1 is provided with the installation sheet 14 for being fixedly connected on by hopper base plate 1 on 3D printer, in order to be fixed in 3D printer by whole hopper. Hopper base plate 1 and hopper pressing plate 3 are aluminium alloy and are made, and will not break when aluminum alloy materials holds photosensitive resin for a long time, it is ensured that the quality of hopper, extend the service life of hopper.
Hopper also includes sealing gasket 4, and sealing gasket 4 is when carrying out 3D and printing, it is possible to play antiseep and cushioning effect, it is to avoid the waste of photosensitive resin and ensure that the molding of photosensitive resin. Sealing gasket 4 offers threeth opening 42 corresponding with the first opening 11 position, size; When 3rd opening 42 and the first opening 11 are equivalently-sized, sealing gasket 4 can be made for elastomeric material, in order to the boss 35 of hopper pressing plate 3 mates with the groove 13 of hopper base plate 1 and is connected; When the 3rd opening 42 is different from the first opening 11 size, the Zhou Changxu of the 3rd opening 42 makes the boss 35 of hopper pressing plate 3 be connected with groove 13 coupling of hopper base plate 1 more than the girth of the boss 35 of hopper base plate 1.
Mould release membrance 2 adopts the poly tetrafluoroethylene of high transmission rate to be made, and the following characteristic of poly tetrafluoroethylene can ensure solidification and the molding effect of photosensitive resin well; 1) not viscous characteristics: the fluoro coatings that Teflon film is is matrix resin with politef, nearly all material does not bond with Teflon film so that the photosensitive resin after solidification very well with hopper disengaging, stick on shaped platform; 2) thermostability: Teflon film has excellent heat-resisting and low temperature tolerance characteristics. Short time can be high temperature resistant to 300 DEG C, and being typically between 240 DEG C-260 DEG C can use continuously, has significant heat stability, and it can work and not brittle under cryogenic temperature, does not at high temperature melt, and long-term illumination non-whitening ensures good translucent effect; 3) moisture resistance: without water stained on its surface and oil, is not easy to during production operation be stained with solution, and as being stained with a small amount of dirt, simple wiping can be removed. Downtime is short, saves man-hour and can improve work efficiency; 4) mar proof: under high load, has excellent anti-wear performance. Under certain load, poly tetrafluoroethylene possesses wear-resistant and inadhesive two-fold advantage; 5) transmitance of air or oxygen is higher 5-10 times than photosensitive resin, the oxygen passed through or air can between mould release membrance 2 and liquid photosensitive resin molding inhibition layer so that consolidation zone mould release membrance 2 and easily separating bottom the resin after solidifying.
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
