本发明中通过提高打印缸的数量可以很高效成倍的提高打印效率。(比如说一个打印缸正在下降,等待刮刀23往打印缸里刮料,一个打印缸已经填满料,准备通过光学引擎照射固化。刮刀23一直以一个恒定的速率不间断的旋转刮料。只需要匹配刮刀23、送料缸活塞、打印缸活塞以及光学引擎照射之间的速率,即可实现不间断打印,所有机构一直在运动。类似于发动机的4个冲程,不管是3缸、4缸、6缸、8缸等,都能匹配一个合适的速率,使他们不间断的提供动力),因此本发明中打印缸的数量直接影响打印机的打印效率,数量越多,打印效率越高。
本发明中一种下沉式光固化打印机设备的工作原理如下:
减速电机20驱动转动轴22带动刮刀23在打印盘4中做旋转运动,进行刮料动作;第一打印缸机构8、第二打印缸机构9和送料缸机构6通过电机10驱动滚珠丝杆19分别带动活塞板16在打印缸中升降运动。
打印时送料缸中的活塞板上升一定高度对打印盘4内进行送料,同时刮刀开始从送料缸处旋转刮料,打印缸中的活塞板依次下降一个层厚,由刮刀刮过来的浆料填满,送料缸内活塞板上升的高度由打印缸的数量决定,打印缸越多,上升的越多。
填满后的打印缸所对应的光学引擎开始依次照射固化;匹配刮刀的旋转速度与光学引擎照射时间,就可以满足打印机多个打印缸的连续不间断打印,实现批量生产。
综上所述,本发明提供了一种下沉式光固化打印机设备,通过在机架上装配光学引擎单元和打印组件,打印组件包括打印盘、送料缸机构、打印缸单元和刮刀装置,通过送料缸机构、打印缸单元和刮刀装置在打印盘上实现打印工作,其中光学引擎单元照射方向朝向打印组件的打印区域,对打印样品起到固化作用,打印缸单元中的打印缸组件的数量决定了打印机的打印效率,数量越多,效率越高,有利于批量化打印。
