Problems solved by technology

The material stored in the feeding cylinder is generally much more than the amount of powder required for molding. The recovery workload after molding is large and it is easy to cause material waste.
The reciprocating movement of the scraper, the constant start and stop in each powder spreading cycle and some idle strokes affect the spreading speed

Embodiment Construction

[0069] The present invention provides a material laying device, which is applied in the material laying procedure of the 3D printing process, including: a material bed 21, and a ring-shaped material laying area is arranged on the material bed 21, such as a circular material laying area, or It may be a rectangular ring-shaped material-laying area; the material-laying device, the material-laying device and the material bed 21 can move relative to the first direction, so that the material-laying device can carry out repeated material-laying along the ring-shaped material-laying area; the driving device is used for Drive the relative movement in the second direction between the laying device and the material bed 21. During the laying process, the distance between the laying device and the material bed 21 is enlarged, and the spiral printing material layer 41 laid in a stacked manner on the material bed . Wherein, the first direction refers to the direction of moving along the annu...

Abstract

The invention provides a material laying system and method. The material laying system and method are applied to a material laying program of a 3D printing process. The material laying system comprises a material bed, a material laying device and a drive device, wherein an annular material laying area is formed on the material bed; the material laying device and the material bed can carry out relative movement in a first direction, so that the material laying device can carry out cyclic material laying along the annular material laying area; and the drive device is used for driving relative movement in a second direction, between the material laying device and the material bed, a distance between the material laying device and the material bed is increased in a material laying process, andprinting material layers are laid on the material bed in a stacking manner. The invention provides a new material laying system and method. An annular laying method is adopted, and an idle stroke canbe cancelled, so that the material laying efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, and in particular to a material laying system and method. Background technique [0002] 3D printing, as a digital model file, constructs a three-dimensional model by printing layer by layer and superimposing layer by layer. There are many printing methods, such as SLS (Selective Laser Sintering), SLM (Selective Laser Sintering Melting), 3DP (in The printing method based on scraping material or powder laying such as SLA (StereoLithography Apparatus) or SLA (StereoLithography Apparatus) on powder bed, in the existing 3D printing device based on scraping material or powder laying process, in the workbench (or It is called a powder bed or a material bed) with a material laying device to lay a layer of flowable printing material (such as powder material, resin liquid or liquid resin and powder mixed slurry), and then control the laser beam according to the information of the printed...
