Tearing handle 83 open has the cam structure 831 coordinated with quick-release handle 84 pushing tows of seat, and quick-release handle seat 84 is arranged on Quick Release pressing plate 81
On；Therefore in the relative pivoting of Quick release 82 of quick-release handle 83, drive cam structure 831 mutually to be pushed up with quick-release handle seat 84
Push away, so as to realize that Quick Release pressing plate 81 compresses or unclamped hopper 20, but be not limited.
Referring to Fig. 7, including step using the manufacture method of the ceramic photocuring 3D printing equipment 100 of the lower exposure formula of the present invention
Have：S001, elevating mechanism 40 drive print platform 30 to sink in the optical solidified liquid of hopper 20 downwards；S002, projecting apparatus 50 will
Solidification light (such as ultraviolet light) is irradiated in hopper 20, is made to sink to solidify on the print platform 30 in optical solidified liquid and one layer
Cured layer；S003, pivot pendulum driver 62 drive pivot to be set a table 61 downward pivots pendulum, make cured layer on print platform 30 with hopper 20
Light solid-liquid peeled off by the edge at interface, certainly, in other embodiments, pivot pendulum driver 62 drives pivot to set a table 61
Upward pivot pendulum, so that the cured layer on print platform 30 is peeled off with the light solid-liquid in hopper 20 by the edge at interface,
Therefore be not limited；S004, elevating mechanism 40 drive print platform 30 to be lifted up height and the pivot pendulum driving of cured layer
Device 62 drives pivot to be set a table 61 resets；Specifically, in the present embodiment, print platform 30 is driven to be lifted up one by elevating mechanism 40
After the height of individual cured layer, then by pivot pendulum driver 62 pivot is driven to be set a table 61 resets；Certainly, in other embodiments, can be by pivot
Pendulum driver 62 drives pivot to be set a table after 61 resets, then drives print platform 30 to be lifted up cured layer by elevating mechanism 40
Highly；Or, the height and pivot pendulum driver 62 that elevating mechanism 40 drives print platform 30 to be lifted up cured layer are driven
Pivot set a table 61 resets be simultaneously carry out；Preferably it is that when performing step S004, the cured layer and hopper 20 on platform 30 to be printed are complete
Just carry out, but be not limited after fully stripped；S005, projecting apparatus 50 are irradiated in light is solidified in hopper 20, and make previous step
One layer of cured layer is molded on obtained cured layer；S006, continuous repeat step S003 obtain threedimensional model to S005；Wherein,
In threedimensional model forming process, circulating pump 71 drives the optical solidified liquid in hopper 20 to circulate.
Compared with prior art, because the ceramic photocuring 3D printing equipment 100 of the lower exposure formula of the present invention also includes stripping machine
Structure 60, mechanism for stripping 60, which includes the pivot that is articulated in around horizontally disposed pivotal axis 90 on board 10, sets a table and 61 and drives pivot to set a table 61
Around pivotal axis 90 do above and below the pivot of pivot pendulum put driver 62, hopper 20 is set a table on 61 installed in pivot, thus on print platform 30 into
When type goes out one layer of cured layer and need to be lifted up, now by pivot pendulum driver 62 drive pivot set a table 61 pivots pendulum and so that pivot sets a table 61
On hopper 20 produce inclination with respect to print platform 30 so that the photocuring of cured layer on print platform 30 and hopper 20
The stripping of liquid is since the edge at interface, so that the peeling force suffered by cured layer is smaller, therefore relative flat by printing
Platform 30 is directly avulsed for model, and stripping is more smooth, does not produce larger vibrations, so as to improve printing precision, is adapted to
The printing of small structure.Simultaneously as the ceramic photocuring 3D printing equipment 100 of the lower exposure formula of the present invention also includes anti-precipitation mechanism
70, anti-precipitation mechanism 70 includes circulating pump 71, recovery flexible pipe 72 and delivery hose 73, reclaims flexible pipe 72 and is connected to circulating pump 71
Between entrance and hopper 20, delivery hose 73 is connected between the outlet of circulating pump 71 and hopper 20 so that circulating pump 71 drives
Optical solidified liquid circulation in hopper 20, strengthens the mobility of photosensitive resin, prevents from the precipitation of ceramic particle to ensure that ceramics are beaten
The reliability of print, so that the ceramic photocuring 3D printing equipment 100 of the lower exposure formula of the present invention can be adapted to ceramic material very well
Printing, can make the products such as dentistry, orthopaedics and microsensor.In addition, due to photo-curing material (i.e. ceramic photosensitive resin mixed liquor)
Extracted out, then returned through delivery hose 73 in hopper 20 by flexible pipe 72 is reclaimed by circulating pump 71, stirred optical solidified liquid,
Keep suspended state, therefore the advantage of anti-precipitation mechanism 70 is to be not required to be equipped with huge transmission device and support, thus cost it is relatively low and
Effect is preferable.
Above disclosed is only the preferred embodiments of the present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still fall within the scope that the present invention is covered.
