Calculus 3D (three Dimensional) constructing method and device

Abstract

The invention relates to a calculus 3D (three Dimensional) constructing method and device. The calculus 3D constructing method mainly comprises the steps: carrying out unit partitioning on large and complex product moulds into small limited polyhedron units by using a mathematical calculus idea, respectively manufacturing the small limited polyhedron units and storing the small limited polyhedron units in a classifying manner, combining the small limited polyhedron units into a large product by a mechanical arm action executing mechanism under the control of a data processing system, and spraying a hot melting polymer on the surfaces of the small limited polyhedron units in the forming process so as to obtain products integrated into a whole. The calculus 3D constructing device mainly comprises an engine base, the mechanical arm action executing mechanism, a multi-freedom-degree bulb connecting device, a hot melting nozzle device, a manipulator executing end and the data processing system, wherein the machine base and the mechanical arm action executing mechanism commonly form a movement main body which is capable of rotating by 360 DEG, and the mechanical arm action executing mechanism is capable of reciprocating on the machine base horizontally. By adopting the method and the device provided by the invention, the processing and manufacturing time can be greatly shortened, the processing cost is lowered, and the labor intensity of an operator is lightened.

Description

technical field [0001] The invention relates to a calculus 3D construction method and device, in particular to a method and device for 3D printing and molding of large and complex plastic products. technical background [0002] At present, 3D printing is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Most of the existing 3D printers use hot melt nozzles, laser beams, light curing and other methods to accumulate and bond metal powder, plastic and other materials layer by layer, and finally superimpose and shape them to produce physical products. Compared with traditional manufacturing methods such as turning, milling, planing, and grinding, it has the advantages of low labor intensity, high speed, and low price. But the current 3D printing technology basically processes and manufactures small products, or assembles them into a whole by processing small parts first. Whe...
