1 is a perspective view of a three-dimensional printing apparatus and a calibration module according to an embodiment of the present invention. For clarity and ease of illustration, FIG. 1 depicts the working carrier 120 in dashed lines. Referring to FIG. 1, in the present embodiment, the three-dimensional printing technique employed by the three-dimensional printing apparatus 10 is, for example, a fused deposition molding technique, which is disposed on the stage 20. The three-dimensional printing device 10 may include a moving mechanism 11 and a heating head 12 connected to the moving mechanism 11, wherein the moving mechanism 11 may have two degrees of freedom of movement to drive the heating head 12 disposed above the stage 20, for example along the Y-axis. The movement is relative to the stage 20 with respect to the Z axis.

The calibration module 100 includes an adapter 110 and a working carrier 120. The adapter 110 is disposed on the stage 20, and the working carrier 120 is rotatably disposed on the adapter 110. In detail, the calibration module 100 further includes a rotating member 130 that is coupled to the working carrier 120 and is assembled to the working carrier 120, for example, by locking, snapping or soldering, or integrally formed with the working carrier 120. On the other hand, the rotating member 130 can include a ball joint or other suitable type of joint and is coupled to the adapter 110 to drive the working carrier 120 to swing relative to the stage 20. As shown in FIG. 1 , the adapter 110 is located between the working carrier 120 and the carrier 20 , the rotating member 130 is located between the working carrier 120 and the adapter 110 , and the heating head 12 is located above the working carrier 120 .

2 and 3 illustrate the calibration process of the calibration module of FIG. 1. Referring to FIG. 1 to FIG. 3, in the embodiment, the adapter 110 has a recess 111 for receiving a portion of the rotating member 130. That is, the contour of the recess 111 is complementary to the partial contour of the rotating member 130. After the heating head 12 moves along the normal direction N of the stage 20 to abut the working carrier 120, the heating head 12 is taken along the contour contour CL (for example, the three-dimensional image of the object to be molded is taken out). One of the two-dimensional slice profiles) moves relative to the work carrier 120. At this time, a corresponding motion trajectory P is generated along the heating head 12 when the contour contour CL moves relative to the working carrier 120.

For example, in the case where the motion track P is not parallel to the stage 20, the heating head 12 will drive the working carrier 120 that is parallel to the stage 10 to swing relative to the stage 20, thereby slightly adjusting the working carrier 120 relative to the stage. The inclination of the stage 20. In other words, the correction module 100 can be used to correct the assembly tolerance of the motion mechanism 11 or the assembly tolerance between the motion mechanism 11 and the heating head 12 to move the heating head 12 along the contour contour CL relative to the work carrier 120. The resulting motion trajectory P is parallel to the working carrier 120. After the foregoing correction, the heating head 12 can follow each of the contour contour lines (for example, a plurality of two-dimensional slice contours extracted from the three-dimensional image file of the object to be formed) in parallel with the motion trajectory of the working carrier 120. The layer prints a plurality of sub-layers on the work carrier 120 to produce a three-dimensional object quickly and accurately.

In the embodiment, the correction module 100 further includes a locking member 140. The locking member 140 is disposed through the adapter 110 to restrict the rotation of the rotating member 130 relative to the adapter 110 by rotation. That is, after the inclination of the working carrier 120 relative to the stage 20 is determined, the locking member 140 can be used to lock the rotating member 130 to the adapter 110, for example, to press the rotating member 130 against the adapter 110. . On the other hand, the calibration module 100 further includes at least one guiding member 150 (schematically showing two juxtaposed guiding members 150) and two oppositely disposed supporting seats 160. The two guiding members 150 are respectively connected to the two supporting seats 160 to be suspended on the stage 20 and located between the working carrier 120 and the stage 20 . The adapter 110 connects the two guiding members 150 and is located between the two guiding members 150, for example. The two guiding members 150 may be linear guiding rods, so as to guide the adapter base 110 and the working carrier plate 120 connecting the adapter seats 110 between the two supporting seats 160, for example, along the X axis with respect to the loading platform 20 motion.

On the other hand, the correction module 100A further includes an adapter 170. The adapter frame 170 is fixed on the carrier 20a, and the adapter 110 is disposed in the receiving portion 171 of the adapter frame 170.

Since the locking member 140 is disposed, for example, on the carrier 20a, the adapter 170, and the adapter 110, the user can adjust the extent to which the adapter 110 is pressed against the rotating member 130 through the portion exposed to the outside of the carrier 20a. Further, in the case where the adapter frame 170 is fixed to the stage 20a, the adapter 110 provided thereon cannot move relative to the stage 20a.

In summary, the calibration module created by the present invention can utilize the swing of its working carrier relative to the stage to be non-parallel to the motion trajectory generated when the heating head moves relative to the stage along each contour contour. The inclination of the working carrier relative to the stage is slightly adjusted during the stage. Thereby, the heating head can print a plurality of sub-layers on the working carrier layer layer by layer along the movement track of the working carrier along each contour contour line, thereby rapidly and accurately producing the three-dimensional object.
