Powder supplying device for colorful 3DP (three-dimensional printing) machine

Abstract

A powder supplying device for a colorful 3DP (three-dimensional printing) machine comprises a computer and a powder supplying box, wherein a top powder supplying mode is used; the powder supplying box is arranged on the top of a forming chamber and is provided with a powder supplying valve and a power mechanism; a powder supplying opening is formed in a portion, which is connected with the powder supplying box, of the forming chamber; the size and the position of the powder supplying opening correspond to those of the powder supplying valve; a powder rotating fan is arranged below the powder supplying opening and is controlled by a stepping motor in the forming chamber; powder sliding plates which are connected with the powder supplying box are arranged on two sides of the powder rotating fan; one of the powder sliding plates is an arc-shaped powder sliding plate; and a powder supplying platform is arranged right below the two powder sliding plates. The powder supplying device for the colorful 3DP machine is suitable for various forming devices in a 3DP technology, owing to the external powder supplying box, the size of the colorful 3DP machine can be greatly reduced under the condition that the forming sizes are the same, and development of a desktop 3DP forming device becomes possible. A dust reducing effect can be high, the powder supplying speed is high, the circumstance that a large amount of powder is compacted and is not easy to push and pave due to the fact that powder paving rolls roll the powder repeatedly in a pressurized manner is avoided, and layers of powder can be paved to a X-Y forming platform smoothly.

Description

Technical field: [0001] The invention belongs to the field of 3DP color three-dimensional printers, in particular to the field of powder supply devices for 3DP color three-dimensional printers. Background technique: [0002] Rapid prototyping technology is a method to realize computer three-dimensional graphics into physical entities. It is based on modern CAD technology, computer control technology, precision servo drive technology, material science, etc., and can produce various objects with very complex shapes. The commonly used processes of rapid prototyping technology include photocuring, selective laser sintering, fused filament deposition production, laminated solid production and three-dimensional printing, etc. The above rapid prototyping technologies, the first four in terms of color, can only produce monochrome thing. The 3D printing is made layer by layer by rapid prototyping and jet molding technology, and finally can realize the process of color printing. [...
