Abstract: The invention provides a monitor circuit, which is used for a fan and receives a driving current and a driving voltage of the fan. The monitor circuit includes sensing circuits and a microcontroller. The sensing circuits respectively sense statuses of the fan and output sensing values. The microcontroller is used for monitoring whether the sensing values exceed preset value ranges respectively to obtain comparison results. The microcontroller outputs warning signals according to the comparison results. Each of the warning signals has a specific frequency.

Abstract: An imaging system for a three-dimensional printer includes a light source component, at least one pattern determining element, a light splitter, a light directing component, and a lens component. The light source component emits a first light and a second light having different wavelengths. The pattern determining element provides the first light and the second light with a first pattern and a second pattern respectively. The light splitter directs the first light and the second light to different directions respectively. The light directing component guides at least one of the first light and the second light, such that the first light and the second light go to a first plane and a second plane respectively. The lens component includes a first lens group and a second lens group, configured to image the first pattern and the second pattern onto the first plane and the second plane respectively.
