Problems solved by technology

However, most of them can only print a single uniform material at present, but in fact most parts and products are composed of multiple or non-uniform materials. Therefore, SLM3D printers that can simultaneously print multiple materials have become an urgent need in the field of rapid prototyping manufacturing
[0004] At present, when printing multiple materials at the same time, it is impossible to classify and recycle the redundant different powders after each layer is sintered, resulting in mixed pollution between different powders, resulting in powder waste and increasing costs

Embodiment 1

[0047] Such as Figure 1-6 As shown, the invention discloses a printer forming cylinder. Wherein, the printer molding cylinder includes a cylinder body 1 , a hollow piston 2 , a powder leakage ring 3 , a powder recovery box 4 and a central base plate 5 .

[0048] The hollow piston 2 is a hollow barrel-shaped structure, the hollow piston 2 is installed in the cylinder body 1, and the hollow piston 2 is sealed and slidably connected with the cylinder body 1; to prevent the protective atmosphere from leaking from the gap between the hollow piston 2 and the cylinder body 1 out, to stabilize the protective atmosphere in the molding chamber while recovering the powder.

[0049] The powder leaking ring 3 is a ring structure, which is installed in the hollow piston 2. The powder leaking ring 3 can rotate the first preset angle each time, and the second preset hole 101 is evenly distributed on the powder leaking ring 3. The powder leaking ring 3 is also evenly distributed with a seco...

Embodiment 2

[0055] In the second embodiment provided by the present invention, the printer forming cylinder in this embodiment is similar in structure to the printer forming cylinder in Embodiment 1, and the similarities will not be repeated, and only the differences will be introduced.

[0056] In this embodiment, it is specifically disclosed that the printer forming cylinder further includes a driving device 6 installed in the hollow piston 2, and the driving device 6 can drive the central base plate 5 to rotate. The driving device 6 can be a servo motor or other motors with a control system. In this embodiment, the driving device 6 is a servo motor as an example, and the hollow piston 2 is controlled by the servo motor. After the laser sinters a layer of powder, the hollow piston 2 descends a preset distance of a layer thickness. The central base plate 5 is controlled by a servo motor, which can rotate a fixed number of turns around the central axis at a certain speed, and the speed an...

Embodiment 3

[0065] Such as Figure 7 As shown, the present invention discloses a method for using a printer forming cylinder. Using the printer forming cylinder in any one of the above embodiments includes the following steps:

[0066] Step S1: Reset the powder leakage ring 3 so that the opening of the powder recovery box 4 to be loaded with powder faces the hole 101 .

[0067] The powder leaking ring 3 can rotate relative to the hollow piston 2, so that the opening of the powder recovery box 4 to be loaded with powder is facing the hole 101 of the powder leaking ring 3 .

[0068] Step S2: Lower the hollow piston 2 by a layer thickness.

[0069] The hollow piston 2 is controlled by a servo motor. When the laser finishes sintering a layer of powder, the hollow piston 2 descends a preset distance of a layer thickness, and the distance of a layer thickness can be set according to the actual needs of the powder.

[0070] Step S3: Spread powder on the central substrate 5 and scrape it flat. ...

Abstract

The invention discloses a printer forming cylinder and a using method thereof. The printer forming cylinder comprises a cylinder body, a hollow piston, a powder leakage ring, powder recycling boxes and a center base plate; the hollow piston is slidably connected with the cylinder body in a sealed mode; the powder leakage ring is installed in the hollow piston and can be rotated by a first preset angle every time, the second preset number of holes are uniformly distributed in the powder leakage ring, the second preset number of slideways are uniformly distributed in the powder leakage ring, andpowder falling onto the slideways can slide into the holes through the slideways; the second preset number of powder recycling box groups are arranged, each powder recycling box group comprises the third preset number of powder recycling boxes, the powder recycling boxes are uniformly distributed under the powder leakage ring, and the size of openings of the powder recycling boxes is not smallerthan that of the holes; and the center base plate is installed in the hollow piston and can enable redundant powder laid on the center base plate to be thrown onto the powder leakage ring through centrifugal force, and the effect that different kinds of powder are thrown into the different powder recycling boxes is achieved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printer forming cylinder and a use method thereof. Background technique [0002] Selective laser melting (SLM) is an additive manufacturing method that uses laser sintering. Its principle is: make metal or non-metal into spherical powder and pave it, and use the laser beam controlled by data file to pave powder for scanning sintering. Repeat the "powder-sintering" steps until a three-dimensional solid is obtained. It is characterized by short production cycles, low development costs, and unlimited shapes of molded parts. [0003] With the continuous development of 3D printing technology, selective laser melting (SLM) technology has also been greatly improved. However, most of them can only print a single uniform material at present, but in fact most parts and products are composed of multiple or non-uniform materials. Therefore, SLM3D printers that can realize sim...
