It is supplemented in and, motor 53 drives supporting plate 23 to decline again, and the thin layer between supporting plate 23 and reservoir counterdie 22 exposes again, makes light
Solidified resin is solidified into the device of designated shape;
(3) light-cured resin is added in the inside of storage box 83, then turns drive rod 85, makes sealing-plug 86 and photocuring
Resin liquid level contacts, and the liquid level of storage box 83 is made to be less than liquid reserve tank 21, when adding light-cured resin toward the inside of liquid reserve tank 21,
Sliding slider 71 makes the liquid level of storage box 83 be higher than the bottom surface of liquid reserve tank 21, and light-cured resin slowly enters under the effect of gravity
The inside of liquid reserve tank 21 can also drive drive rod 85, drive rod 85 that driving plate 87 is driven to slide, and the internal pressure of storage box 83 becomes
Greatly, light-cured resin is made to enter the inside of liquid reserve tank 21 by conduit 82, when the light-cured resin of the inside of cleaning liquid reserve tank 21
When, so that the liquid level of storage box 83 is less than liquid reserve tank 21, drive drive rod 85, storage box 83 is made to become with the space that sealing-plug 86 surrounds
Greatly, atmospheric pressure presses the inside that light-cured resin enters storage box 83 from conduit 82, opens valve 81 and discharges light-cured resin
To the inside of storage barrel, keep storage storage photocurable liquid resin more convenient, and reduce print structure 2 and its photocuring liquid
The time of contact of state resin and external light source effectively prevents photocurable liquid resin solidification, substantially increases photocurable liquid
The storage quality of resin.
The setting of the storage organization 8 of the present invention stores the photocurable liquid resin of the inside of print structure 2 convenient for storage, and
Convenient for adding photocurable liquid resin toward the inside of print structure 2 when equipment works, operating flexibility energy is substantially increased, together
When storage organization 8 be set to guide frame 7 on, convenient for adjust guide frame 7 on storage organization 8, make storage store photocuring liquid
State resin is more convenient, and reduces the time of contact of print structure 2 and its photocurable liquid resin and external light source, effectively
Photocurable liquid resin solidification is prevented, the storage quality of photocurable liquid resin is substantially increased, the setting of driving structure 5 makes to beat
Print is more stablized, while convenient for the device of printing different height, while shading cover 6 engages with driving structure 5 and its shell 1, makes
Shading cover 6 is fixed more convenient.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the description in the above embodiment and specification only illustrates the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement is both fallen in the scope of protection of present invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
