Problems solved by technology

Due to the low strength of the binder and other factors, this molding technology has the following defects: 1. The strength of the parts is low, and only conceptual models can be made; 2. Most of the formed parts need to be post-processed, and the process is complicated
This forming system has the following disadvantages: 1. It is difficult to peel off the waste materials after forming, especially the waste materials inside the complex parts; 2. The tensile strength and elasticity of the paper material prototype are insufficient; Moisture-proof treatment; 4. The surface of the prototype has a step texture, which needs to be polished, and the refinement is insufficient
According to the traditional technology, it is difficult for the tool to cut the inside of the workpiece with complex internal structure

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Below in conjunction with accompanying drawing, the present invention is further described:

[0020] Step 1: The model analysis system processes the model to obtain the data information of the contour of each layer of the model, that is, the coordinate information (X, Y) of each contour point. The origin of the coordinates can be any point, and the coordinates of all contour points are based on the origin Determine its coordinate value, and pass the data information of each layer to the control system layer by layer through the interface;

[0021] Step 2: The film material supply device sen...

Abstract

The invention relates to a 3D (Three-dimensional) desktop printing method and system. Compared with the traditional method, the difference is characterized in that an adhesive is only sprayed in the current layer of contour area in the printing process, and the cutting is carried out on a layer after the adhering is carried out on the layer. The method and the system provided by the invention have the beneficial effects of greatly saving processing auxiliary materials and reducing the manufacturing cost of processing equipment.

Description

technical field [0001] The invention relates to a laminated solid forming technology, in particular to a desktop 3D printing method and system. Background technique [0002] Desktop nozzle printing technology (Three-dimensional printing, 3DP) is to "print" the interface of the part on the powder material with a binder through the nozzle, and the process belongs to the 3D printing technology based on the three-dimensional printing process. Every time a layer is bonded, the forming cylinder is lowered by a layer thickness distance, and the powder feeding mechanism is flattened to feed the powder and compact it, and the next layer is sprayed and bonded. Due to the low strength of the binder and other factors, this molding technology has the following defects: 1. The strength of the parts is low, and only conceptual models can be made; 2. Most of the formed parts need to be post-processed, and the process is complicated. [0003] The LOM method usually sends the thin material c...
