Abstract

The purpose of the present invention is to provide a bed level control system of a 3D printer. The system enables the level of the bed to be easily controlled at the most appropriate conditions by marking the most suitable level points on respective corner parts for controlling a level of the bed, and allowing a user to see the level points to judge whether the level of the bed is abnormal or not, thereby enabling the user to control the level of the bed according to the level points when the level of the bed is abnormal. A bed level control system of a 3D printer according to the present invention includes: a polygonal bed (20) which is correspondingly formed by respective sides which are shorter than those of a polygonal base (10), and is positioned above the base (10) in a state that there is a gap between the base (10) and the polygonal bed (20); a plurality of springs (30) which are installed between bottom surface portions adjacent to respective corners of the bed (20) and top surface portions of the base (10) which are positioned underneath the respective bottom surface portions; and a plurality of level control parts (40) which are installed on top surface portions of the base (10) adjacently to the respective corners of the bed (20). The level control part (40) includes: a nut (42) of which a certain portion of the outer side of a top part is cut out to form an L character shaped protrusion, which is installed such that the nut is set up on the top surface portion of the base (10) to enable the protrusion to support a certain portion of a side which is adjacent to the bed (20), and has a second symbol (43) marked on a certain portion of the surface of the top part thereof; and a bolt (44) which is inserted into the nut through a washer having the certain portion put on the top surface portion of the bed (20) located above the projection according to the rotation, and controls a level of the bed (20) such that a level of the bed (20) becomes the most appropriate conditions when a first symbol (45) marked on a certain portion of the surface of the bottom part of a bolt head and the second symbol (43) closely face each other.

Description

[0001] The present invention relates to a 3D printer,

The present invention relates to a bed level control system of a 3D printer.

Generally, in a 3D printer, a head is formed by spraying a supplied filament onto a bed with a nozzle provided and stacking a very thin film on the bed to complete the object from the bottom to the top of the object.

It is very important to maintain and adjust the bed level uniformly by completing the target object on the bed in this way.

In this regard, in the conventional 3D printer, when the printing quality of a target article is low, the level of the bed is adjusted depending on the experience of the user, so that the level of the bed is not uniform and the printing quality of the article is improved It was difficult.

Therefore, by displaying the most suitable level point for each part for adjusting the level of the bed, the user can see the level point and judge whether or not the level of the bed is abnormal, so that when the level of the bed is abnormal, So that the level of the bed is easily adjusted to the most suitable state.

1 is a perspective view illustrating an embodiment of a bed level control system for a 3D printer according to the present invention.
2 is an exploded perspective view showing an embodiment of the level adjusting unit shown in FIG.
3 is a cross-sectional view showing an embodiment of the level adjusting unit shown in FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view illustrating an embodiment of a bed level control system for a 3D printer according to the present invention, and includes a base 10, a bed 20, a spring 30, and a level controller 40.

Hereinafter, the present invention will be described with reference to FIGS. 2 and 3. FIG.

FIG. 2 is an exploded perspective view showing an embodiment of the level adjusting section 40 shown in FIG. 1. The level adjusting section 40 includes a nut 42, symbols 43 and 45, a bolt 44, and a washer 46).

3 is a cross-sectional view showing an embodiment of the level adjusting section 40 shown in FIG. However, for the sake of understanding, the bolt 44 is not shown in a cross-sectional view, but is viewed from the front where the first symbol 45 is seen from the center.

1 to 3, first, the rectangular bed 20 is formed to correspond to a shorter side of each side of the quadrangular base 10 and is spaced on the base 10.

The gap between the base 10 and the bed 20 is adjusted by four springs 30 and four level adjusting portions 40 and the four springs 30 and the four level adjusting portions 40, The following is an explanation.

That is, four springs 30 are provided between each bottom surface adjacent to each corner of the bed 20 and the top surface of the base 10 located below each bottom surface. In this case, the four springs 30 are formed in a spiral shape, and when they are applied at a certain pressure, they are reduced, and when the pressure is removed, they are increased.

The four level adjusting portions 40 are provided on the upper surface of the base 10 adjacent to the respective corners of the bed 20.

An embodiment of the level controller 40 is as follows.

First, the nut 42 has an L-shaped protrusion formed by cutting out a predetermined portion of the upper end of the nut 42 and is installed on the upper surface of the base 10 so as to support a portion of the adjacent side of the bed 20 by the jaw And a second symbol 43 is displayed on a predetermined portion of the top surface. At this time, it is preferable that the second symbol 43 is a triangle having one vertex pointing upward.

The bolt 44 is inserted into the nut 42 through the washer 46 having a certain portion placed on the upper surface of the bed 20 located on the jaw according to the rotation and adjusts the level of the bed 20, So that the level of the bed 20 becomes the most suitable when the first symbol 45 shown in FIG. In this case, the first symbol 45 may be a triangle having one vertex pointing downward.

That is, when the first symbol 45 is located close to the second symbol 43 in the four level adjusting sections 40, it means that the level of the bed 20 is most appropriate and uniform .

In the present invention, a level point most suitable for each corner portion for adjusting the level of the bed 20 is displayed, and the user looks at the level point to determine whether or not the level of the bed 20 is abnormal, The user can adjust the level of the bed 20 to the level most easily by adjusting the level of the bed 20 so that the level of the bed 20 can be easily adjusted to the optimum level, So that the printing quality of the article can be easily improved.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.
