Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly...

Abstract

The invention relates to a 3D printer and a powder laying method thereof. The 3D printer comprises a mounting frame, a forming cylinder and a powder laying part, wherein the forming cylinder comprisesa forming shell and a forming platform, the forming shell is arranged on the mounting frame, and the forming platform is arranged on the forming shell in a reciprocating mode in the first direction;and the powder laying part is arranged on the mounting frame in a reciprocating mode in the second direction, the powder laying part comprises a flexible scraper, a powder supply unit and a residual powder recovery unit, the powder supply unit is arranged between the flexible scraper and the residual powder recovery unit, when the powder laying part moves, the powder supply unit lays forming powder on the forming platform, the flexible scraper scrapes the forming powder flat, and the residual powder recovery unit sucks residual powder in the process that the flexible scraper scrapes the forming powder flat. The 3D printer is low in powder laying acting force, and the printing success rate can be increased.

Description

technical field [0001] The invention relates to the field of processing equipment, in particular to a 3D printer and a powder spreading method thereof. Background technique [0002] Powder bed 3D printer (hereinafter referred to as printer) is one of the important branches of additive manufacturing equipment. It lays a thin layer of fine powder on the opening area of ​​the forming cylinder of the printer through a powder spreading device, and then sprays it with laser, electron beam, and micro-droplets. And other means, selectively treat the thin layer of fine powder, so that the powder in the selected area is combined into a sheet-like whole. Through the layer-by-layer descending of the printed substrate in the forming cylinder, and the repeated execution of powder spreading and selective processing steps, each layer of powder solidification is vertically accumulated with the previous solidification until a complete three-dimensional entity is generated. [0003] Due to th...
