Problems solved by technology

Once the cantilever is extended to a certain range, it will vibrate violently during the printing process, seriously affecting the printing effect
For long cantilever platforms, the usual solution is to install a motor at each end of the platform to drive the pallet mechanism to move; but this will bring several new problems: a. The motors may be out of sync, resulting in a decrease in printing accuracy; b. Setting two motors takes up a lot of space and is not easy to arrange; c. The double motors are difficult to hide and affect the appearance; d. The cost is high

Embodiment 1

[0040] Such as figure 1 As shown, a 3D printing platform includes a print box 2 connected to a support. The print box 2 is a square cavity with an upper opening. The support includes a plurality of horizontal supports and vertical supports. The print box 2 is connected to the horizontal supports. The vertical support includes a support group 1, which is connected to the horizontal support. The bottom of the support group 1 is provided with a lifting support leg 4. The horizontal section of the support leg is rectangular, and the aspect ratio of the section is 1:0.3. The ratio of the length to the width of the bracket group is 0.4:1. The horizontal support includes a first support rod 3 and a second support rod 5. The length ratio of the first support rod and the second support rod is 1.7:1. The first support rod 3 and the second support rod 5 are connected to the bottom side of the printing box 2 The edges are connected. One end of the first rod 3 is movably connected with a ...

Embodiment 2

[0042] Printing includes the following steps,

[0043] Step 1: Adjust the height of the support feet and the support legs, adjust the angle of the rotating rod, and the height of the support rod, so that the print box 2 is in a horizontal and stable state, and the upper end of the support group 1 is connected to the print head;

[0044] Step 2: Turn on the temperature control device in the printing box 2 and adjust the printing box 2 to be within the constant temperature range of 17~24℃;

[0045] Step 3: The print head prints in the gel liquid, and rotates the wheel as needed to drive the paddle to wave the gel liquid, so that the object printed in the gel liquid rotates;

[0046] Step 4: After the printing is completed, the printed product is irradiated with ultraviolet light with a wavelength of 50~90nm and rinsed with water several times.

Embodiment 3

[0048] The gel liquid consists of 14 parts by mass of hexamethoxymethyl melamine, 23 parts of acrylate, 10 parts of methoxypolyethylene glycol acrylate, 27 parts of polyether polyol, 22 parts of pentanediol polyester polyol and 37 parts Composition of polycarboxylic acid. Among them, the polyether polyol is polyether triol; the polycarboxylic acid is a saturated pentacarboxylic acid; the pentanediol polyester polyol is a pentanediol polyester diol; the particle size of the gel liquid is 5 μm. The supporting force of the gel liquid is 2.1N / cm 2 .

Abstract

The invention discloses a gel solution for a 3D (Three Dimensional) printing platform and belongs to the field of printing platforms. The gel solution disclosed by the invention is prepared from the following components in parts by mass: 14 to 22 parts of hexamethoxy methyl melamine, 23 to 35 parts of acrylic ester, 10 to 17 parts of methoxy polyethylene glycol acrylate, 27 to 38 parts of polyether polyol, 22 to 30 parts of pentadiol polyester polyol and 37 to 45 parts of polycarboxylic acid. The gel solution disclosed by the invention can stably keep the shape and can show good liquidity whena low-intensity shear force is applied; when a 3D printing material stays put, the gel can provide support for the 3D printing material; when a needle head used by a printing head moves in gel, the gel around the needle head flows without hindering the movement of the needle head; after the needle head moves away, the gel around the needle head can restore an original shape.

Description

[0001] This application is a divisional application with the title of "A 3D Printing Platform" [0002] The filing date of the original application: 2016-05-31 [0003] The application number of the original application is: 2016103766030. Technical field [0004] The invention relates to a printing platform, in particular to a gel liquid used for a 3D printing platform. Background technique [0005] The printing platform is one of the key components of a 3D printer, which requires stability and reliability. The quality of the printing platform directly affects the printing effect. There are generally two types of commonly used printing platforms. One is to use a motor as a power source to drive the pallet mechanism up and down on one side of the printing platform. Since the motor acts on one end of the pallet mechanism, the pallet mechanism is affected by one side. Force, the other side becomes a cantilever, and as the cantilever lengthens, it will cause the stiffness to decrease an...
