Display screen made of electroluminescent diode has self-luminous organic electric exciting light-emitting diode, have contrast is high, thickness is thin,
The excellent characteristics such as visual angle is wide, reaction speed is fast, it is wide to can be used for flexibility panel, use temperature range, construction and processing procedure are simpler.
OLED display screen 8 has extension 81 and Projection Division 82, and Projection Division 82 is opposite with 51 position of bottom plate of forming tank 5
It answers, the size of Projection Division 82 is adjusted in extension 81.Extension 81 has unfolded state 81b and rolled state 81a, projection
Portion 82 is connect with extension 81.When extension 81 is in unfolded state 81b, the area of Projection Division 82 becomes larger.When extension 81
When in rolled state 81a, the area of Projection Division 82 becomes smaller.The quantity of the present embodiment extension 81 is two, two extensions
81a, 81b are connect with the both ends of Projection Division 82 respectively.
The OLED display screen 8 of the present embodiment photocuring three-dimensional printer 1 can crimp, such as cylindrical surface screen, nothing
Dead angle.When needing to print large-sized object, the extension 81 of OLED display screen 8 is unfolded, large-breadth printing may be implemented, from
And realize the 3D printing that miniprinter carries out large-sized object.OLED display screen 8 can be such that 3D printing imitates by the characteristic of itself
Fruit is more preferable, and printing precision is high, and energy consumption is lower and contrast is higher than LCD display.And the processing procedure of OLED display screen 8 is simpler
It is single, make the simple production process of photocuring three-dimensional printer 1, and be conducive to storage and transportation, greatly reduces production cost.
The Method of printing of the present embodiment photocuring three-dimensional printer 1 include the steps that it is following, firstly, execute addition step,
Moulding material 6 is added in forming tank 5, moulding material 6 can be photosensitive resin, and photosensitive resin can be existing for three-dimensional
The photosensitive resin of forming objects.Moulding material 6 can be liquid, it is preferable that liquid has certain stickiness.Moulding material 6
Adding manner can be added at one time or realize the lasting benefit to the moulding material 6 in forming tank 5 using the system that is automatically added to
It fills.
Then, it executes and adjusts projected area step, the three-dimensional object model if necessary to printing is smaller, and just OLED is shown
The extension 81 of screen 8 is rolled up, and extension 81 is made to be in rolled state 81a, thus make the Projection Division 82 of OLED display screen 8
Area becomes smaller；If necessary to printing three-dimensional object model it is larger when, just being unfolded in the extension 81 of rolled state 81a,
Extension 81 is set to be in unfolded state 81b, so that the area of Projection Division 82 be made to become larger.
Then, projection step is executed, light processor 7 issues light beam, and it is flat that light beam is irradiated to printing behind Projection Division 82
On the moulding material 6 of the bottom on platform 3.
Thereafter, curing schedule is executed, solidifies the moulding material 6 of the bottom on print platform 3 in forming tank 5.
Then, control device 2 controls print platform 3 and moves straight up, repetitive cycling above-mentioned projection step and solidification
Step, until forming the three-dimension object 4 needed.
The Method of printing of the present embodiment photocuring three-dimensional printer 1 can be according to need due to the extension 81 of OLED display screen 8
The size for the three-dimensional object model to be printed adjusts the size of the Projection Division 82 of OLED display screen 8, to realize small
Type printer can carry out the 3D printing of large-sized object, and printing precision with higher, energy consumption are also low.
Photocuring three-dimensional printer second embodiment:
As the explanation to the utility model photocuring three-dimensional printer second embodiment, below only to three-dimensional with photocuring
The difference of printer first embodiment is illustrated.
OLED display screen have extension and Projection Division, extension have opening state and folded state, Projection Division with prolong
The connection in exhibition portion.When extension in the open state, the area of Projection Division becomes larger.When extension is in folded state, throw
The area in shadow portion becomes smaller.
The OLED display screen of the present embodiment photocuring three-dimensional printer can fold, when needing to print large-sized object
When, expansion OLED display screen is in the extension of folded state, and large-breadth printing may be implemented, realize miniprinter into
The 3D printing of row large-sized object.OLED display screen keeps 3D printing effect more preferable by the characteristic of itself, and printing precision is high, and energy consumption is more
Low and contrast degree is higher than LCD display.And the processing procedure of OLED display screen is simpler, makes the life of photocuring three-dimensional printer
Production. art is simple, and is conducive to storage and transportation, greatly reduces production cost.
The Method of printing of the present embodiment photocuring three-dimensional printer include the steps that it is following, firstly, execute addition step,
Moulding material is added in forming tank, moulding material can be photosensitive resin, and photosensitive resin can be existing for three-dimension object
Molding photosensitive resin.Moulding material can be liquid, it is preferable that liquid has certain stickiness.The addition side of moulding material
Formula can be added at one time or realize the lasting supplement to the moulding material in forming tank using the system that is automatically added to.
Then, it executes and adjusts projected area step, the three-dimensional object model if necessary to printing is smaller, and just OLED is shown
The extension of screen is folded up, and extension is made to be in folded state, so that the area of the Projection Division of OLED display screen be made to become smaller；Such as
When the three-dimensional object model that fruit needs to print is larger, just the extension in folded state is unfolded, is in extension and opens
State, so that the area of Projection Division be made to become larger.
Then, projection step is executed, light processor issues light beam, and light beam is irradiated on print platform behind Projection Division
The bottom moulding material on.
Thereafter, curing schedule is executed, the mold material cures of the bottom on print platform are made in forming tank.
Then, control device control print platform moves straight up, the above-mentioned projection step of repetitive cycling and solidification step
Suddenly, until forming the three-dimension object needed.
The Method of printing of the present embodiment photocuring three-dimensional printer can be beaten as needed due to the extension of OLED display screen
The size of the three-dimensional object model of print adjusts the size of the Projection Division of OLED display screen, to realize miniprinter
The 3D printing of large-sized object can be carried out, and printing precision with higher, energy consumption are also low.
Above embodiments, only preferred embodiments of the utility model, be not to limit the utility model practical range, therefore it is all
