Embodiment Construction

[0035]The grid-based rapid prototyping manufacturing proposed by the present invention is also based on the principle of discrete or accumulation forming, and can also be regarded as a rapid prototyping technology; the RP technology in the usual sense discretizes the model into a lamellar structure, while the grid-based rapid prototyping manufacturing technology The model is discretized into triangular meshes, so there is an essential difference between meshed rapid prototyping and RP technology in the usual sense, which can be regarded as the expansion and improvement of the existing RP technology. The grid-based rapid prototyping manufacturing method can also be regarded as a spatial surface layered manufacturing method.

[0036] In general, the surface accuracy of RP forming parts directly depends on the thickness of the sheet. Therefore, in order to improve the accuracy of the part, the thickness of the sheet is usually very thin. Limited by the manufacturing principle, the...

Abstract

The invention relates to a meshed rapid prototyping method. The meshed rapid prototyping method comprises the following steps of: (1) acquiring the three-dimensional model of an object to be processed; (2) dispersing the three-dimensional model into meshed units and carrying out simulation analysis, wherein the meshed units are basic manufacturing units, and the basic manufacturing units comprise sheet pieces and rod pieces for connecting with the sheet pieces; (3) cutting plate materials and wire materials to respectively form the sheet pieces and the rod pieces of the basic manufacturing units; and (4) connecting the sheet pieces with the rod pieces in the basic manufacturing units to finish the rapid prototyping of the object to be processed. The invention provides the meshed rapid prototyping method through which the rapid prototyping of large-sized structures can be finished, the rapid prototyping can be truly achieved, and the effect of the rapid prototyping of large-scale molds or parts is achieved.

Description

technical field [0001] The invention belongs to the technical field of rapid manufacturing, and relates to a method for manufacturing a grid rapid prototype. Background technique [0002] Rapid prototyping technology (RP technology for short) is an advanced manufacturing technology developed in the late 1980s. Different from traditional processing methods such as "deformation forming" and "removal forming", RP technology is based on discrete or accumulation forming. The basic principle of the new digital forming technology is to discretize the three-dimensional solid model into a series of two-dimensional sheets with tiny thickness in a certain direction. , bonding and other means to make it stack up layer by layer into one, so as to complete the rapid prototyping of the designed new product samples, models or molds, and even the entire entity. RP technology can greatly shorten the processing cycle, reduce the cost of product development, and play a positive role in promoti...
