Embodiment Construction
[0042] Embodiments of the present invention describe a 3D printing device and its image exposure system, and the image exposure system uses a digital micromirror element as an area array image source.
[0043] figure 2 An image exposure system of a 3D printing device according to an embodiment of the present invention is shown. refer to figure 2 As shown, the image exposure system 200 of the present embodiment includes a light source 201, a bandpass color filter 202, an integrating rod 203, a relay optical element 204, a reflector 205, a digital micromirror element 206, and a TIR (Total Internal Reflection, all internal reflection) prism 207, projection lens 208 and controller (not shown). For the sake of clarity, components not relevant to the present invention are not shown.
[0044] The light source 201 is used to generate light beams to be irradiated onto the DMD 206 . The wavelength of the light emitted by the light source 201 depends on the cured photosensitive mater...
