Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific embodiments

[0037] Such as figure 1 A product molding method based on FDM technology shown includes the following printing steps:

[0038] (1) According to the input two-dimensional graphics data of the bottom surface, print the contour of the first layer of graphics on the bottom surface, and print at least one circle along the contour;

[0039] (2) After printing along the contour, the end point of the last printing is the starting point of the internal structure of the bottom surface of the printing, and the internal structure is printed in a reciprocating motion in a line manner;

[0040] (3) After the first layer of graphics is printed, the print head moves to the peripheral contour of the next layer of graphics according to the coordinates set by the two-dimensional graphics data, and returns to step (1) until the printing of all the bottom layers of graphics is completed Perform the nex...

Abstract

The invention belongs to the technical field of 3D printing, and discloses a product molding method based on a FDM technology. The product molding method comprises: (1) printing the circumferential contour of the first layer pattern of a bottom surface according to the input two-dimensional pattern data of the bottom surface; (2) printing an internal structure in a reciprocating movement manner byusing the previous printing ending point as a starting point for printing the bottom surface internal structure; (3) after printing the first layer pattern, moving a printing head to the circumferential contour of the next layer pattern according to the coordinates set by the two-dimensional pattern data, and returning to the step (1) until the patterns on all layers of the bottom surface are completed; (4) moving the printing head to the circumferential contour of the pattern on the bottom surface; (5) printing a side wall by the printing head according to a designed spiral lifting path until the side wall is printed; and (6) if the product has a top surface, returning to the step (1), and printing the top surface by using the same method as the bottom surface printing, otherwise, endingthe printing. According to the present invention, the printing efficiency of the method is high.

Description

Technical field [0001] The present invention relates to the field of 3D printing technology, and in particular to a method for forming shell products based on FDM technology. Background technique [0002] FDM is Fused Deposition Molding and it is a kind of 3D printing technology, which has a vital position in the field of 3D printing. FDM molding technology mainly relies on the movement of the print head and the printing platform to realize the construction of three-dimensional models. In the entire 3D printing process, the wire plays a vital role. The FDM equipment squeezes the material out in a semi-fluid state, and the material solidifies into a thin layer with contours in time. The accumulation of layers forms the entire three-dimensional part. Its advantages are stable dimensional accuracy, long service life, short production cycle, and gradually began to be applied in various industries. [0003] In view of the above working principles of FDM, FDM desktop printing small cra...
