Embodiment Construction

[0035]The meshed rapid prototyping proposed by the present invention is also based on the principle of discrete or stacked forming, and can also be regarded as a rapid prototyping technology; the RP technology in the general sense discretizes the model into a sheet structure, while the meshed rapid prototyping 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 perfection of existing RP technology. The grid-based rapid prototyping method can also be regarded as a layered manufacturing method of space surfaces.

[0036] In general, the surface accuracy of RP formed 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 RP forming efficiency of large parts is often relatively lo...

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 gridded rapid prototype manufacturing method. Background technique [0002] Rapid prototyping technology (referred to as RP technology) is an advanced manufacturing technology developed in the late 1980s. Unlike traditional material processing methods such as "deformation forming" and "removal forming", RP technology is based on discrete or accumulation forming The principle of new digital forming technology, the basic principle is to discretize the three-dimensional solid model into a series of two-dimensional sheets with a small thickness in a certain direction. The rapid prototyping machine uses specific materials to manufacture sheet entities, and through fusion, polymerization , bonding and other means to make it pile up layer by layer into one, so as to complete the rapid prototyping of the designed new product sample, model or mold, or even the entire entity. ...
