Description
Technical field
The part of DLP photocuring 3D printers is the utility model is related to, more particularly to one kind can be consolidated quick change film DLP light soon
Change 3D printer resin storage tank.
Background technology
The operation principle of DLP photocuring 3D printers：There is the liquid resin of light sensitive characteristic for part, using digital light
Processing (DLP) technology realizes the successively solidification of resin, and final molding is a 3-dimensional model.Which is face exposure shaping, once
The pattern of a flood can be printed, speed is fast, and Forming Quality is high.
DLP photocuring 3D printers are broadly divided into two large divisions, and software section is used to handle model, model is cut into slices
Processing, is converted into plane picture and is input in DLP imaging systems.Hardware components receive model data, and successively printing is final
Produce required model.And hardware components are broadly divided into three big modules：Projecting light path, resin storage tank, print platform.One complete
Whole 3D printing flow is as follows：The 3-dimensional model of the part of manufacture required for being established first with CAD software, then being cut with related
Picture into many pieces of picture format, is then imported DLP system, then showed by dmd chip by model treatment by piece software
The pattern imported on picture, being projected on dmd chip and reflexed to a branch of parallel ultraviolet adjusted by lens group will
The resin trench bottom of shaping, form dynamic mask.Under the irradiation of ultraviolet light cross-linking reaction occurs for the resin with light sensitive characteristic,
It is solidified into inputting picture identical pattern, is still liquid without the resin by ultraviolet light.The thickness of single printable layer
The distance that degree depends on manufacturing platform and resin trench bottom (is generally 50~100 μm, can adjusted according to required printing precision
Section), resin solidifies since liquid bath bottom, then stops continuing up solidification when it touches manufacturing platform, and then manufacture is flat
Platform rises, and cured resin separates with liquid bath bottom, reserves next layer of solidification space, then repeatedly the step for be finally completed
Manufacture.In the fabrication process, the process that resin separates with resin trench bottom is referred to as release, the power overcome required for separation be referred to as from
Type power, if off-type force is excessive, may result in cured sample depart from from manufacturing platform or cured layer between stripping
It can not continue from manufacture failure is ultimately resulted in.
The method one kind for currently solving this release problem is that (it is good that base material is generally translucency in resin trench bottom
Lucite or quartz glass) coating Silicon moulds or does other surfaces processing, this processing mode is disposable, once tree
Fat bottom land, which is destroyed or damaged, then must entirely change resin storage tank.
After a long time use, the tension effects of film can be reduced gradually photocuring 3D printer resin storage tank at present,
At this moment this problem can only be improved by more renewing film so that resin storage tank changes that membrane process is complex, and the level of tightness of film
It can not adjust, still there is many inconvenience in actual use.

Industry.
After polyfluorinated ethylene membrane is arranged on resin storage tank, it is tauted by the effect film of press box and is attached to glass
In glass plate, when DLP photocurings 3D printer carries out DLP photocurings 3D printing operation, liquid resin is thin from perfluoroethylene-propylene
Start to solidify on film, stop exposure after then touching preceding layer cured layer, manufacturing platform is begun to ramp up, and perfluoroethylene-propylene is thin
Film rises together with starting with the part that solidified resin contacts, and because film is tauted in itself, and has certain elasticity,
With the rising of manufacturing platform, film produces the pulling force of an oblique lower section so that film is from cured sample edge and sample
Separation, and restored to the original state by the elasticity of itself, then carry out next layer of printing.
Polyfluorinated ethylene membrane natural resiliency in the state of long-term tighten can be deteriorated, and service life can also reduce, and
And taut tighter service life is lower, therefore different printing precision are directed to, the position that can adjust the press box of upper end cover adjusts
The taut strength degree of polyfluorinated ethylene membrane, the lower sample of taut more tight more suitable printing thickness.
As described above, it can preferably realize the utility model.
Embodiment of the present utility model is simultaneously not restricted to the described embodiments, and other are any without departing from of the present utility model
Spirit Essence with made under principle change, modification, replacement, combine, simplification, should be equivalent substitute mode, be included in
Within the scope of protection of the utility model.
