DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIGS. 1 and 2. The first embodiment of the present invention provides a 3D printer which comprises a device body 100 and a scanning module 200.

The form of the device body 100 of the present invention is not limited, but a printing plane 101 has to be formed on the device body 100 to allow a 3D model (not shown) to be printed on the printing plane 101. In the current embodiment, the device body 100 preferably has a lifting platform 110. The printing plane 101 is formed on the top of the lifting platform 110 and can move vertically. The scanning module 200 is arranged on the lifting platform 110 and is disposed corresponding to the printing plane 101, the configuration detailed below. The scanning module 200 comprises a module body 210, a closure mechanism 220, and a flat scanner 230.

In the current embodiment, the module body 210 of the scanning module 200 comprises a base 211 fixed on the lifting platform 110 and a movable cover 212 stacked detachably above the base 211. The gap between the base 211 and the movable cover 212 forms a feeding channel 201 penetrating through the module body 210. The feeding channel 201 extends horizontally in parallel with the printing plane 101. The feeding channel 201 is disposed corresponding to a side edge of the printing plane 101; one end opening of the feeding channel 201 is immediately adjacent to the side edge of the printing plane 101. Besides, the bottom of the feeding channel 201 is flush with the printing plane 101 or higher than the printing plane 101. The closure mechanism 220 is connected between the base 211 and the movable cover 212; the closure mechanism 220 is used to close the feeding channel 201 selectively. In the current embodiment, the closure mechanism 220 is a rebound device and can shrink and stretch. The closure mechanism 220 in the compressed state will stretch if pressed; the closure mechanism 220 in the stretched state will shrink if pressed. Two ends of the closure mechanism 220 are individually connected with the base 211 and the movable cover 212. Pressing the lowered movable cover 212 can cause the closure mechanism 220 to stretch such that the movable cover 212 is lifted and separated from the base 211 to open the feeding channel 201. Pressing the lifted movable cover 212 can cause the closure mechanism 220 to shrink such that the movable cover 212 moves close to the base 211 to close the feeding channel 201. The flat scanner 230 is disposed in the feeding channel 201 correspondingly. In the current embodiment, the flat scanner 230 is disposed on the base 211 and faces the interior of the feeding channel 201 to scan the image inside the feeding channel 201, but the present invention is not limited to this. For example, the flat scanner 230 also can be disposed on the movable cover 212 and disposed facing the interior of the feeding channel 201 to scan the image inside the feeding channel 201. The flat scanner 230 is electrically connected with a control module 300 (e.g., Micro Control Unit/MCU). Also, the control module 300 is electrically connected with the nozzle assembly 310 and the pen assembly 320.

The structures of the nozzle assembly 310 and the pen assembly 320 are based on the existing techniques, which will be explained briefly only, not in detail, in the current embodiment. The nozzle assembly 310 may comprise the extrusion nozzle 311 and the track 330 on which the extrusion nozzle 311 moves. The pen assembly 320 may comprise the coloring nozzle 321 and the track 330 on which the coloring nozzle 321 moves. In general, the extrusion nozzle 311 and the coloring nozzle 321 are connected with each other, disposed on the same track 330, and move at the same time. The extrusion nozzle 311 is used to extrude melted plastics as layers on the printing plane 101 and stack the layers to form the model 20. The coloring nozzle 321 is used to paint on the surface of the model 20. The control module 300 controls the extrusion nozzle 311 and the coloring nozzle 321 to move on the track 300 to the predetermined printing position or the predetermined painting position.

When the flat scanner 230 is not used, the feeding channel 201 can be closed to prevent the dust generated during the operation of the extrusion nozzle 311 from adhering to the flat scanner 230 and from reducing the scan quality of the flat scanner 230.

Please refer to FIGS. 1, 3, and 5. The user pushes a pictorial paper 10 manually into the feeding channel 201. Then, the flat scanner 230 scans the pictorial paper 10 passing through the feeding channel 201 and sends the scan image to the control module 300. The control module 300 controls the pen assembly 320 to color the surface of the model 20 according to the pictorial paper 10 during the printing of the model 20 such that that the pictorial paper 10 can be painted on the surface of the model 20.

Please refer to FIGS. 1, 5, 6A, 6B, and 6C. When a picture is required to be painted on a surface area 21 of a recess of the model 20, a 3D data which defines the predetermined painting position corresponding to the surface area 21 is firstly loaded into the control module 300. The control module 300 receives the scan image of the pictorial paper 10 from the flat scanner 230 in which the pictorial paper 10 is predetermined to be painted on the surface area 21. Also, the control module 300 associates the 3D data with the scan image. The control module 300 can receive the scan image at any moment during the printing process. As show in FIG. 6A, the control module 300 controls the nozzle assembly 310 to print and stack the sliced layers in the surface area 21 according to the 3D data. Then, the printing process is paused and a semifinished model is formed with the surface area 21 exposed. As shown in FIG. 6B, the control module 300 controls the pen assembly 320 to paint the picture on the surface area 21 according to the scan image. As shown in FIG. 6C, after the picture has been painted, the control module 300 continues to control the nozzle assembly 310 to print and stack the sliced layers to form the protruding portion of the edge of the surface area 21 and the other portions of the model 20.

Please refer to FIG. 7. The structure of the 3D printer according to the second embodiment of the present invention is roughly similar to that according to the first embodiment in which the similar parts are not detailed again here. The difference between the first and the second embodiments is that in the second embodiment, the module body 210 is a mono-piece body and the feeding channel 201 is disposed in the module body 210. Also, the disposed location of the feeding channel 201 in the second embodiment is the same as that in the first embodiment and will not be described again. The closure mechanism 220 at least comprises a movable plate 221 pivoted to the module body 210. The upper edge of the movable plate 221 is pivoted to the module body 210 and thus the movable plate 221 can be driven by the gravitation to pivot downward to close the feeding channel 201. The closure mechanism 220 can further comprise a flexible restorer 222. In the current embodiment, the flexible restorer 222 is preferably a spring. Two ends of the spring are individually pressed against the module body 210 and the movable plate 221; therefore, the movable plate 221 can be pivoted to the module body 210 using the lower edge thereof such that the flexible restorer 222 moves the movable plate 221 to pivot upward to close the feeding channel 201. When the flat scanner 230 is not used, the feeding channel 201 can be closed to prevent the dust from adhering to the flat scanner 230 and from reducing the scan quality of the flat scanner 230. When the pictorial paper 10 passes through the feeding channel 201, the movable plate 221 can be pushed to open.

The 3D printer of the present invention can scan the flat image and paint it on the surface of the model 20 by means of the flat scanner 230 disposed corresponding to the printing plane 101.

The above-mentioned embodiments are preferably ones, but not limited to these. As shown in FIG. 8, the scanning module 200 also can be disposed on the device body 100 corresponding to the lifting platform 110, not disposed on the lifting platform 110. The lifting platform 110 can ascends and descends vertically to move the printing plane 101 to be flush with the scanning module 200, which facilitates the scanning process.

The embodiments disclosed in the above description are only preferred embodiments of the present invention, but not to limit the scope of the present invention. The scope of the present invention should be embraced by the accompanying claims and includes all the equivalent modifications and not be limited to the previous description.
