Designated position after, controller 11 control light source 5 start light projector T2, expose T2 after the completion of, No. two charging trays 9 of second station 2
Stripping machine starts to start peeling motion, and controller 11 controls mobile mechanism 6 and starts that light source 5 is driven to be moved at the same time；Such as
Fruit (prints or is printed without using second station 2 and completed, do not have post-exposure picture) without exposure image, then controller
11, which directly control mobile mechanism 6, makes No. three charging tray 10 moved beneaths of the light source 5 to 3rd station 3, does not do and stops at second station 2
It stays.
STEP4: control system judges whether 3rd station 3 has exposure image exposure to be extracted according to executable data, such as
Fruit has exposure image, then control system judges that 3rd station 3 needs to expose, and just controls mobile mechanism 6 and light source 5 is driven to be moved to the
Fixation position immediately below No. three charging trays 10 of three stations 3 reaches specified below 3rd station 3 three charging trays to light source 5
Behind position, control system controls light source 5 and starts light projector T3, after the completion of exposing T3, the stripping machine of No. three charging trays 10 of 3rd station 3
Start to start peeling motion, the mobile mechanism 6 of control system control at the same time starts to drive light source 5 mobile；If without exposure diagram
Piece (is printed or is printed without using 3rd station 3 and completed, do not have post-exposure picture), then controller 11 directly controls
Mobile mechanism 6 moves optical system directly to the No.1 charging tray 7 of the first station 1 from No. two charging trays 9 of second station 2, not to
It moves in No. three 10 directions of charging tray of 3rd station 3.
STEP5: after light source 5 is reset to 7 position of No.1 charging tray of the first station 1, controller 11 judges the one of the first station 1
Whether the peeling action of first layer is completed on number charging tray 7, if the removing of No.1 charging tray 7 is completed, optical system starts next layer of throwing
Light；If the removing of No.1 charging tray 7 does not complete, the removing of No.1 charging tray 7 is first waited to complete, optical system starts next layer of light projector again.With
This analogizes, No. three charging trays 10 of No. two charging trays 9 of second station 2 and 3rd station 3 if necessary to expose be also required to etc. it is to be stripped
Movement is completed just start light projector.
STEP6: after any one molding terminates in three shaped platforms, controller 11 identifies the station exposure image
All exposure finishes, and light source 5 will not again expose charging tray corresponding to the shaped platform, skips the molding in moving process
Platform continues exposure to two shaped platforms of residue until three models are fully completed printing.
