Embodiment 1

[0049] Such as figure 1 As shown, a semi-enclosed space 3D printer includes a bottom plate 1 and a 3D printing mechanism 5, and the top of the bottom plate 1 includes a horizontal telescopic mechanism 4, a vertical telescopic mechanism 3 and a rotation mechanism 2 in sequence from top to bottom;

[0050] Such as figure 1 and figure 2 As shown, the rotating mechanism 2 includes a first motor 21 and a first disk 22, the bottom of the first motor 21 is fixedly connected with the middle part of the upper end surface of the base plate 1 by bolts, and the middle part of the lower end surface of the first disk 22 is connected with the first The top welding of the output shaft of the motor 21;

[0051] Such as figure 1 and image 3 As shown, the longitudinal telescopic mechanism 3 includes a first cylinder 31 and a second disc 32, the bottom of the first cylinder 31 is fixedly connected with the middle part of the upper end surface of the first disc 22 by bolts, and the bottom of...

Embodiment 2

[0074] The difference from Example 1 is that the outer walls of the first inner rod 331 and the second inner rod 431 are sprayed with lubricating liquid, and the lubricating liquid is prepared by the following method:

[0075] Take the following raw materials and weigh them by weight: 10 parts of white oil, 4 parts of glycerin, 8 parts of turpentine, 7 parts of sorbitol, 4 parts of boric acid, 7 parts of glyceryl oleate, 3 parts of palmitoleic acid, 6 parts of antioxidant, 5 parts of antirust agent, 4 parts of defoamer;

[0076] A: Material preparation: first weigh the above raw materials;

[0077] B: Oleyl alcohol mixing: first pour white oil, glycerin, turpentine, and sorbitol into a constant temperature magnetic stirrer, turn on the constant temperature magnetic stirrer to stir and heat, the speed is 50r / min, and the temperature is controlled between 85 degrees Celsius;

[0078] C: Ester fusion: pour boric acid, glyceryl oleate and palmitoleic acid into a constant temperat...

Embodiment 3

[0083] The difference with embodiment 2 is the preparation of lubricating liquid, and its specific preparation method is as follows:

[0084] Take the following raw materials and weigh them by weight: 14 parts of white oil, 8 parts of glycerin, 10 parts of turpentine, 9 parts of sorbitol, 8 parts of boric acid, 11 parts of glyceryl oleate, 7 parts of palmitoleic acid, 10 parts of antioxidant, 7 parts of antirust agent, 8 parts of defoamer;

[0085] A: Material preparation: first weigh the above raw materials;

[0086] B: Oleyl alcohol mixing: first pour white oil, glycerin, turpentine, and sorbitol into a constant temperature magnetic stirrer, turn on the constant temperature magnetic stirrer to stir and heat, the speed is 70r / min, and the temperature is controlled between 95 degrees Celsius;

[0087] C: Ester fusion: pour boric acid, glyceryl oleate and palmitoleic acid into a constant temperature magnetic stirrer and stir for 30 minutes;

[0088] D: Additives: Pour the ant...

Abstract

The invention discloses a semi-closed space 3D printer. A horizontal telescopic mechanism, a longitudinal telescopic mechanism and a rotating mechanism are sequentially arranged above a bottom plate from top to bottom; the rotating mechanism comprises a first motor and a first disk, and the middle of the lower end face of the first disk and the top of an output shaft of the first motor are welded;the longitudinal telescopic mechanism comprises a first air cylinder and a second disk, and the bottom of the second disk and the top of a piston rod of the first air cylinder are welded; the horizontal telescopic mechanism comprises a first rectangular plate, a second air cylinder and a second rectangular plate; a 3D printing mechanism comprises a 3D printing mechanism main body, and 3D printinggun heads are all connected with the 3D printing mechanism main body through feeding pipes. The semi-closed space 3D printer can conveniently perform quick three-dimensional printing in a semi-closedspace, the service life of a first inner rod and a second inner rod is prolonged, the device can be conveniently pushed and located, and the printing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a 3D printer in a semi-enclosed space. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, ar...
