Description
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.
Therefore, applicant think be necessary to above-mentioned existing DLP photocuring 3D printer resin storage tank do further structure improve.
Utility model content
The purpose of this utility model provides a kind of DLP photocuring 3D printer resin storage tank in order to promote DLP photocuring 3D printing effect 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 cell body, described cell body forms primarily of the base plate of hard and carriage two parts, the bottom of described carriage is formed with periphery installed surface, soft backing plate is provided with in the below of periphery installed surface, backing plate is fixedly fitted on periphery installed surface, fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film is folded with between periphery installed surface and backing plate, Self-Clinching Standoffs is equipped with in the surrounding of base plate, on each Self-Clinching Standoffs, screw thread is connected with countersunk bolts, the counterbore inwall of each countersunk bolts is equipped with internal thread, above-mentioned each Self-Clinching Standoffs is all to one should be had to be socketed with helical spring fastening bolt, each fastening bolt runs through periphery installed surface and the backing plate of carriage, and spin in the counterbore of corresponding countersunk bolts, and counterbore runs through backing plate and periphery installed surface apical grafting, and helical spring is positioned at the top of periphery installed surface, described base plate is provided with opening, described opening is positioned at carriage, and on opening, be covered with transparent shrouding, and fixed by cambered surface press box, when carriage is at helical spring active force, when keeping pressed status, described cambered surface press box extend partially into in carriage, and tighten fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film.
Fluorinated ethylene propylene copolymer film in above-mentioned or polytetrafluoroethylene film are all existing materials directly can bought, therefore applicant no longer describes in detail to both films above-mentioned at this.
Above-mentioned middle provided a kind of DLP photocuring 3D printer resin storage tank, the carriage in its structure
Under external force, can move relative to base plate.Therefore, when the resin storage tank of said structure is bonded on DLP photocuring 3D printer, its base plate is fixed on the work top of DLP photocuring 3D printer, carriage is then movable relatively, the DLP photocuring 3D printer of said structure is when carrying out the 3D printing of DLP photocuring, carry along with on print platform, resin in resin storage tank just carries out successively curing and demolding, above-mentioned print platform often on carry once, the carriage of resin storage tank synchronous by carry, now helical spring compression, fluorinated ethylene propylene copolymer film in carriage or polytetrafluoroethylene film leave cambered surface press box, the fluorinated ethylene propylene copolymer film now originally tightened or polytetrafluoroethylene film relax instantaneously, and the deformation quantity corresponding with above-mentioned print platform pick up height can be there is.Now act on the gas on print platform, hydraulic coupling just reduces relatively, and the resin of lower will produce certain hydraulic coupling to the junction of printable layer and fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film (higher position namely on fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film) on fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film, above-mentioned junction is easily first peeled away by external force from periphery gradually, the vacuum area causing the junction of above-mentioned printable layer and fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film to be formed progressively reduces, the resin of such solidification just can the peeling off with fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film of relative ease.
In order to promote above-mentioned periphery installed surface and fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film between the two and above-mentioned backing plate and fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film between the two be sealed with validity, above-mentioned periphery installed surface and fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film pad between the two and are provided with layer of silica gel; Pad same with between fluorinated ethylene propylene copolymer film or polytetrafluoroethylene film of above-mentioned backing plate is provided with layer of silica gel.
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.
