Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The instant application claims priority to Korean patent application No. 10-2016-0039980 filed on Apr. 1, 2016, the entire content of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a printing method of a 3D printer.

BACKGROUND ART

A 3D printer is a device for making a three-dimensional real object by successively injecting predetermined raw materials and stacking the raw materials layer by layer in a minute thickness on the basis of a 3D plan. The 3D printer has been developed for manufacturing objects, and various products may be manufactured using the 3D printer.

An existing 3D printer stacks raw materials on a bed successively. At this time, if the bed is not agreeably coupled with a raw material at an initial stage, a printout may shrink and bent as the melted raw material is cooled. This is because a material of the bed is different from the raw material and thus the raw material is not easily adhered to the bed.

In addition, if a printout (a 3D object) is output onto the bed and then it is intended to output another printout, the printout on the bed should be removed and then the bed should be set to the 3D printer again. Thus, the existing 3D printer is not able to output several printouts successively.

DISCLOSURE

the method comprising:

(a) positioning a first bed 31 between the pair of transfer modules 21, 22 to be in contact with the pair of transfer modules 21, 22;

(b) when the pair of transfer modules 21, 22 moves the first bed 31 downwards, by the nozzle control module 10, controlling the nozzle 11 to discharge raw materials and thus printing a first printout 100 on the first bed 31, and also forming a first support 41 on the first bed 31 around the first printout 100 to make a friction with the pair of transfer modules 21, 22;

DESCRIPTION OF DRAWINGS

FIG. 1 is a flowchart for illustrating a printing method of a 3D printer according to an embodiment of the present disclosure.

FIGS. 2 to 9 show examples of the printing method of a 3D printer according to an embodiment of the present disclosure.

BEST MODE

Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. These embodiments are just for illustrations for a person having ordinary skill in the art to easily implement the present disclosure, but this does not mean that the feature and scope of the present disclosure are limited to these embodiments.

FIG. 1 is a flowchart for illustrating a printing method of a 3D printer according to an embodiment of the present disclosure, and FIGS. 2 to 9 show examples of the printing method of a 3D printer according to an embodiment of the present disclosure.

A 3D printer 1 of this embodiment includes:

a nozzle control module 10 configured to transfer a nozzle 11 to a predetermined location on a plane; and

a pair of transfer modules 21, 22 disposed perpendicular to the plane and spaced apart from each other.

The nozzle control module 10 and the pair of transfer modules 21, 22 are coupled to a frame 2. The nozzle 11 is coupled to the nozzle control module 10, and the nozzle control module 10 may move the nozzle 11 to a specific location on the plane. The nozzle control module 10 includes guide bars which intersect each other, and the nozzle 11 may move along with the guide bars in x-axis and y-axis directions on the plane.

The pair of transfer modules 21, 22 is disposed perpendicular to the plane on which the nozzle 11 moves. The pair of transfer modules 21, 22 is spaced apart from each other and coupled to the frame 2. A printout is located between the transfer modules 21, 22. The pair of transfer modules 21, 22 may move the printout downwards from the nozzle 11. The transfer modules 21, 22 may adopt various configurations such as rollers, belts, caterpillars or the like.

By using the 3D printer 1 as described above, a printing method of a 3D printer is performed according to the following order.

In S11, a first bed 31 is located between a pair of transfer modules 21, 22 to be in contact with the pair of transfer modules 21, 22.

The first bed 31 is located between the pair of transfer modules 21, 22. The first bed 31 may have a hexahedral shape. As sidewalls of the first bed 31 make a friction with the pair of transfer modules 21, 22, the first bed 31 is located between the pair of transfer modules 21, 22 (see FIG. 3).

In S12, when the pair of transfer modules 21, 22 moves the first bed 31 downwards, the nozzle control module 10 controls the nozzle 11 to discharge raw materials so that a first printout 100 is printed on the first bed 31, and also forms a first support 41 on the first bed 31 around the first printout 100 to make a friction with the pair of transfer modules 21, 22 (see FIG. 4).

Even though a printout has been simply printed on a bed in an existing technique, in this embodiment, when the first printout 100 is printed on the first bed 31, the first support 41 is also printed simultaneously to be in contact between the pair of transfer modules 21, 22. The first support 41 is a kind of wall and may have a box shape. The first printout 100 is located at an inner side of the first support 41.

In the 3D printer 1 of this embodiment, after the pair of transfer modules 21, 22 push the first bed 31 downwards, the first support 41 is located between the pair of transfer modules 21, 22 to give a support force, and thus the entire structure including the first printout 100 does not fall down.

In S13, after the first printout 100 is completely made, a second bed 32 is formed above the first printout 100 to be coupled to the inner portion of the first support 41.

If the first printout 100 is completely made, a second bed 32 on which a second printout 200 is formed is printed thereon. Since the second bed 32 is made of the same material as the first printout 100 and the second printout 200, they are not deformed, for example bent, due to coupling or shrinkage thereof.

In S14, the second printout 200 is formed on the second bed 32, and also a second support 42 is formed around the second printout 200 to make a friction with the pair of transfer modules 21, 22.

While the second printout 200 is formed (or, printed) on the second bed 32, the second support 42 is also printed. The second support 42 is required for the pair of transfer modules 21, 22 to push the second bed 32 downwards. Therefore, when the second printout 200 is formed, the second support 42 is formed simultaneously to make a friction between the pair of transfer modules 21, 22. In this way, the second support 42 and the second printout 200 may be formed simultaneously.

After the second printout 200 is completely made, a third bed may be formed thereon, and a third printout and a third support may be formed on the third bed. In this way, printouts may be formed successively.

Therefore, even though a worker outputs several printouts, the printouts may be printed successively without cessation. In addition, since the bed and the printout are made of the same material, they may be coupled excellently.

Moreover, it is possible to print not only an elongated printout but also a long printout with a complicated inner structure.

The embodiments of the present disclosure have been described in detail. However, the embodiments are just for illustrations and not intended to limit the scope of the appended claims. Many changes, modifications and equivalents can be made thereto by those having ordinary skill in the art, and such changes, modifications and equivalents also fall within the scope of the present disclosure.
