Problems solved by technology

The gypsum powder with higher printing effect is expensive, reaching 1000 yuan / kg
However, if the powder in the powder chamber is exposed to the air for a long time, it will be damp and agglomerated, making it impossible to print, resulting in waste of materials and a large loss of economic value.

Embodiment Construction

[0015] Such as figure 1 , figure 2 , a kind of 3D powder printing equipment comprises frame 1, and printing platform 11 is arranged on frame 1, and printing platform 11 is provided with the powder chamber of two upper openings, and one is printing chamber 31, and another warehouse chamber 32, The printing platform 11 is provided with a printing head 4 and a powder spreading scraper 5. The printing head 4 is connected to the Y-axis rail 22 through a slider. The rails 21 are respectively fixed on both sides of the printing platform 11 .

[0016] The print head 4 can move in a two-dimensional plane, and its two-dimensional movement is realized by the X-axis track 21 and the Y-axis track 22 . Specifically, the print head 4 slides on the X-axis track 21 to determine the X-axis position, and the X-axis track 21 can slide on the Y-axis track 22 to determine the Y-axis position.

[0017] The bottom plate 33 of the printing room 31 and the warehouse room 32 can reciprocate up and d...

Abstract

The invention relates to a 3D powder printer which comprises a rack, wherein a printing platform is arranged on the rack, two powder cabins with openings at upper parts are arranged on the printing platform, one is a printing chamber and the other is a warehouse chamber, and heating plates are arranged below the bottom plate(s) of the printing chamber and / or the warehouse chamber. The invention further discloses a dampproof method of the powder of the printer. Compared with the prior art, the 3D powder printer and powder dampproof method thereof have the following benefits: the heating plates are arranged below the bottom plate(s) of the printing chamber and / or the warehouse chamber, and the heating plates can rise the temperature of the powder cabins, so as to prevent powder in the powder cabins from being affected with damp and caking. Proved by a large quantity of experiment data, when no dampproof equipment is arranged, the caking rate is 0.5-1%, and the caking rate after improvement is 0.05-0.1%. Therefore, the caking rate is lowered, and a large quantity of consumables is saved.

Description

technical field [0001] The invention relates to a 3D powder printing equipment and a powder moisture-proof method. Background technique [0002] At present, there are many kinds of 3D printing equipment, which are used in different industries. The printing material of the powder printer can be powder such as gypsum powder. For example, the invention patent with application number 201511003016.9 and titled "a multi-functional multi-nozzle color 3D printing equipment and printing method based on 3DP technology" discloses a 3D powder printer. There are two powder chambers, one is the printing chamber and the other is the storage chamber. The printing platform is equipped with a printing head. The printing head moves in a two-dimensional plane, and its two-dimensional movement is realized through the X-axis track and the Y-axis track. Printing is also achieved through layer stacking. When printing starts, a certain thickness of powder is laid in the printing room, and one laye...
