Description
Technical field
This utility model relates to 3 D-printing field, specifically, relating to a kind of photocuring 3 D-printing device.
Background technology
Three-dimensional (3D) prints is based on Three Dimensional Design Model, by software hierarchy and numerical control molding, recycles laser
The materials such as metal dust, ceramic powders, plastics, photosensitive resin are passed through successively to pile up by the mode such as bundle, hot melt nozzle, illumination curing
The technology of the mode superposition molding cohered, finally produces entity products.
Photocuring 3 D-printing (stereolithography apparatus method, SLA) is a kind of very important 3 D-printing method, and it is main
Wanting operation principle is to use the light of certain frequency to form three-dimensional body after successively solidifying liquid light maleate resin.
Digital light processes the device that (DLP) photocuring three-dimensional printer is one of which SLA type.Digital light processes
(DLP) operation principle of photocuring three-dimensional printer is to utilize DLP technology, and light source uses projector imaging, and light source successively solidifies
Liquid photosensitive resin, prints the three-dimensional body that resolution is higher, and its resolution exceeds typical Fused Deposition Modeling (FDM) class
The 3D printer of type.
DLP photocuring 3D printer mainly has software and hardware two parts.Hardware includes printer frame, projector light
Source, print platform and photosensitive resin groove.Print platform can move up and down in photosensitive resin groove, and in photosensitive resin groove
Equipped with photosensitive resin.The signal of video signal that software section produces, after digital processing, projects to photosensitive tree by projector light source
The bottom of fat groove, the photosensitive resin in such photosensitive resin groove can become solid by instaneous polymerization, and the photosensitive tree not contacted with light
Fat then keeps liquid, thus successively generates three-dimensional body in the plane that print platform is relative with photosensitive resin groove.
Publication No. is that the Chinese invention patent application of CN104085106A discloses a kind of DLP three-dimensional printer, and it includes

Being irradiated, DLP scialyscope is located at the lower section of forming tank and is connected with computer, and DLP projector projects profile graphics
Figure light path with irradiation and solidifies liquid photocurable resin through the base plate transmission of forming tank, thus prints layer by layer and three-dimensional mould
The three-dimensional body that type is corresponding.
But the structure of existing three-dimensional printer easily has a problem that, it is simply that such photocuring three-dimensional is beaten
Print machine is in the solidification process of photosensitive resin, and it is three-dimensionally shaped inefficient.
It addition, the structure of this three-dimensional printer there is also Second Problem, after printing one layer, due to printing objects layer
Still in the photosensitive resin groove of liquid, so when print platform moves up, printing objects layer and photosensitive resin groove bottom
Between will form vacuum, print platform needs to overcome printing objects layer by vac sorb active force and possible adhesion
Power.Owing to printing objects layer and photosensitive resin groove bottom are rigid disengagements, the stripping result of printing objects layer so can be affected, by
Being to carry out constructed object by the way of successively printing in DLP three-dimensional printer, each printing objects layer is required to and photosensitive resin
Groove bottom completes a demoulding, therefore can have a strong impact on the molding effect that object is final, the most also can affect printer overall
Service life.
The digital light provided in the Chinese utility model patent of notification number CN204955433U processes three-dimensional printer
Platform assembly includes the gripper shoe unit vertically moved up and down；For carrying the print platform of printing objects；Print flat
Platform can be dynamically connected with gripper shoe unit, so that described print platform tilts when demoulding, be reset to horizontal level after demoulding.This
Scheme to some extent solves the separation problem of printing objects layer and photosensitive resin groove bottom, improves the flat of printing objects
Whole property.But, the structure of this platform assembly is complex, not only increases manufacturing cost, and its platform assembly in the application
The problem that precise decreasing even cannot normally work the most easily occurs.
