Description

DLP photocuring 3D printer resin storage tank

Technical field

The utility model relates to a kind of parts of DLP photocuring 3D printer, particularly a kind of DLP photocuring 3D printer resin storage tank.

Background technology

The operation principle of DLP photocuring 3D printer: adopt digital light process (DLP) technology to use a projecting apparatus successively to solidify liquid photosensitive resin.It can print the object with very fine-resolution, has exceeded the 3D printer of typical melt filament manufacture (FFF).

DLP photocuring 3D printer mainly contains software and hardware two parts composition.Above-mentioned hardware components mainly includes printer frame, projecting apparatus, print platform and resin storage tank.In specific works, the pantostrat structure of print platform sinks in resin storage tank, resin storage tank is wherein exactly the cylinder body of a dress photosensitive resin substantially, software part produce signal of video signal after digital processing (DLP) again by projector out, this projected light contacts with photosensitive resin after through the bottom of resin storage tank.This time photosensitive resin instaneous polymerization of contact becomes solid (i.e. printable layer, thickness is generally 25 ~ 30 μm), the photosensitive resin do not contacted with light can be also then keep liquid, thus will vacuum be formed between printable layer and the inner bottom surface of resin storage tank, make printable layer be subject to hydraulic pressure and atmospheric acting in conjunction power.Consider current resin storage tank on the whole in rigidity, material generally selects glass or acrylic, its trench bottom cannot produce certain deformation quantity, print platform overcomes deadweight and gas, hydraulic coupling and above put forward and just need to apply larger external force, improve the requirement to printer frame overall construction intensity, and printer frame is also easily damaged; Rigid disengagement bottom printable layer and resin storage tank simultaneously, also can affect the stripping result of printable layer, because DLP photocuring 3D printer is that mode by successively printing carrys out constructed object, in an above-mentioned whole process each printable layer all need with resin storage tank bottom complete a demoulding, therefore the resin storage tank of said structure can have a strong impact on the final molding effect of object, cannot promote its surface smoothness.

Summary of the invention

The purpose of this utility model is the DL P photocuring 3D printer resin storage tank providing its trench bottom a kind of can produce obvious deformation under external force to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, a kind of DLP photocuring 3D printer resin storage tank designed by the utility model, comprise transparent cell body, it can select glass material or acrylic material, through hole is offered at the trench bottom of transparent cell body, and on this trench bottom, also sealing is equipped with transparent flexible layer, and this transparent flexible layer covers above-mentioned through hole completely.

When above-mentioned a kind of resin storage tank specifically uses in DLP photocuring 3D printer, the projected light of projecting apparatus contacts with liquid light maleate resin after through transparent flexible layer.This time liquid light maleate resin instaneous polymerization of contact becomes printable layer, the liquid light maleate resin do not contacted with light can be also then keep liquid, thus will vacuum be formed between the bottom surface of printable layer and transparent flexible layer, and then the External Force Acting that applying one is relatively little is on print platform, and in conjunction with the gas pressure power bottom transparent flexible layer, print platform will first by lifting height, and transparent flexible layer is then that the deformation quantity corresponding with above-mentioned print platform pick up height can occur.Now act on the gas on print platform, hydraulic coupling just reduces relatively, and the liquid photosensitive resin of lower will produce certain pressure to the junction (higher position namely on transparent flexible layer) of printable layer and transparent flexible layer on transparent flexible layer, above-mentioned junction is easily peeled away by external force, the vacuum formed between the bottom surface of final printable layer and transparent flexible layer is destroyed, print platform can be promoted easily, simultaneously because printable layer and transparent flexible layer realize the demoulding by mutually peeling off, therefore the stripping result of printable layer is better.

As preferably, the transparent flexible layer in above-mentioned is primarily of Teflon basement membrane and the solid state si glue-line composition being compounded in its upper surface, and wherein the thickness of Teflon basement membrane is 0.1 ~ 0.3 ㎜, and the thickness of solid state si glue-line is 4 ~ 6 ㎜.Without in external force situation in this preferred version, after filling with liquid light maleate resin in resin storage tank, the transparent flexible layer be made up of the solid state si glue-line of thickness to be the Teflon basement membrane of 0.1 ~ 0.3 ㎜ and thickness be 4 ~ 6 ㎜ in above-mentioned can ensure sufficient intensity, avoids deforming; And when print platform being formed printable layer, when this printable layer has needed with transparent flexible pull-up mould, deformation just can occur the transparent flexible layer of said structure, producing certain deformation quantity thus ensureing that stripping action completes smoothly; Simultaneously again because silica gel does not have viscosity, the demoulding quality on printable layer surface after therefore further reducing demoulding difficulty and promoting the demoulding.

The elasticity of above-mentioned transparent flexible layer after a long time use can slowly exhaustion, thus have influence on demoulding efficiency and the stripping result of resin storage tank entirety, therefore the transparent flexible layer conveniently bottom resin storage tank can be changed easily, above-mentioned transparent flexible layer further comprises basement membrane frame, the sealing of this basement membrane frame is located in the border of Teflon basement membrane, and its integral sealing is laid on the trench bottom of transparent cell body.The transparent flexible layer of said structure can be the silicone adhesive by coating transparence on basement membrane frame at the concrete sealing paving mode of trench bottom, then basement membrane frame and trench bottom is directly bonded; Or also can be by other mechanical seal locking modes by the transparent flexible layer of said structure directly and trench bottom fit.

Above-mentioned thickness is the Teflon basement membrane of 0.1 ~ 0.3 ㎜, silica gel material and silicone adhesive are conventional products on the market at present, therefore applicant is not further detailed above-mentioned technology contents at this.

A kind of DLP photocuring 3D printer resin storage tank that the utility model obtains, it has energy-conservation, promotes economic benefit; Improve the remarkable advantages such as the printing objects surface smoothness of DLP photocuring 3D printer simultaneously.
