[0073] like Figure 2-1 and Figure 2-4 As shown, the frame includes a column 111 and a bottom plate 112. The column 111 is a strip-like object with a rectangular cross-section stretched along the up-down direction.

[0074] The 3D printer lifting device is composed of a guide rail 141, a slider 142, a platform support 143, a printing platform 144 and a motor drive mechanism. The guide rail 141 is a linear guide rail fixed on the front surface of the column 111 parallel to the longitudinal direction of the column 111. The slide block 142 slides on the guide rail 141, and the front surface of the slide block 142 is parallel to the sliding direction. The platform support 143 is an "L"-shaped cantilever structure viewed from the left side. The plane at the rear is matched and fixed to the front surface of the slider 142. The upper part is fixedly connected with the printing platform 144. The upper surface of the printing platform 144 is connected to the The planes at the rear o...

[0079] On the basis of the 3D printer example 100, the innovative design of the bottom plate and the platform bracket enables the 3D printer to realize the folding function; the change of the rotating arm and the nozzle movement device can realize another compact structure; increasing the number of nozzles makes the The 3D printer realizes functions such as support printing, multi-color and multi-material printing.

[0080] Specifically, at least three elongated legs 113 are used, and the bottom of the column 111 is rotatably connected to one end of the leg 113, and the axis of rotation is parallel to the length direction of the column 111. Preferably, as Figure 3-4 As shown, three supporting legs 113 are used, all of which are elongated. The bottom surface of one end is provided with a foot pad 114 at the lowest point, and the other end is provided with a stepped hole penetrating the surface along the up and down direction, and the fastener 115 passes through the step. The h...

[0089]In order to make the carrying of the 3D printer more convenient, a carrying case is designed on the basis of the 3D printer example 2 101. The design of the carrying case requires the folded 3D printer to be firmly and reliably restrained inside the carrying case, so that it will not be bumpy during transportation. And the vibration makes the printer parts shake; further carrying cases also need to integrate printing rolls, which saves the inconvenience of additional carrying; further carrying cases also need to integrate batteries, so that the 3D printer can be used without a fixed power supply or in the field still work.

[0090] The box body includes an upper box body 211 and a lower box body 212. The upper box body 211 and the lower box body 212 cooperate to form a space for accommodating a 3D printer with the legs 113 in a folded state and the printing platform 144 in a folded state. Specifically, if Pic 4-1 As shown, the box body is composed of an upper box body ...

Abstract

The invention discloses a portable 3D printer, and belongs to the field of 3D printers. On the basis of a feeding device and a control system in the prior art, remaining portions are creatively designed. The printer comprises a stand column fixed with a box body during work and a printing platform driven by a third motor to linearly move in the length direction of the stand column; during folding, the printing platform can rotate around the axis perpendicular to the length direction of the stand column, the top of the stand column is rotatably connected with a rotating arm, a first motor drives the rotating arm to rotate around the axis parallel to the length direction of the stand column, a nozzle is in sliding connection with the rotating arm, and a second motor drives the nozzle to do linear motion in the length direction of the rotating arm, and a box body containing the 3D printer in the folding state is further included; according to the 3D printer, the nozzle moves in the space in a cylindrical coordinate system manner, the compact structural design is achieved, the manufacturing cost is reduced, and after folding, the printer can be arranged in the box body to be carried.

Description

technical field [0001] The invention belongs to the field of 3D printers, in particular to a portable 3D printer. Background technique [0002] 3D printer is a device that applies rapid prototyping technology. It is based on digital model files and uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. The structure that is difficult or even impossible to process, combined with Internet technology, realizes the electronic transmission of objects in a sense, and is an extremely important processing equipment. [0003] At present, 3D printers are mainly used in professional and industrial fields, and it is difficult to promote them to families and individuals. The main reason is that in order to meet the requirements of the print head moving in three-dimensional space, traditional 3D printers use Cartesian coordinate system or parallel arm structure. With three degrees of freedom of movement, three sets of sliding devices ar...
