Method for making rock bedding structure model based on 3D printing technology

Abstract

The invention provides a method for making rock bedding structure model based on a 3D printing technology. The method includes the following steps that N rock stratum three-dimensional models of the same property are designed with CAN software; the obtained three-dimensional models are subjected to layered processing and saved in the format of STL; data are transmitted to a computer, and N printing parameters and printing raw materials are selected; N models are printed continuously with a 3D printer, control software controls a printer nozzle to melt the materials according to layered information, spraying is conducted point by point, one layer of printing is completed, and the printer controls a software control platform to ascend along the Z axis to continue curing of subsequent printing layers till the model is obtained. According to the method, the 3D printing technology is utilized to rapidly make the rock bedding structure model stratum by stratum, rock stratums representing different density, composite particles and particle arrangement modes are concentrated into one model, defects existing in the stratums are printed accurately, a rock prototype can be adjusted according to research requirements, and time and economic cost of a small number of customized models are reduced.

Description

technical field [0001] The invention relates to 3D printing technology, in particular to a method for making a rock bedding structure model based on 3D printing technology. Background technique [0002] In the production of small batches, custom molds are required, resulting in increased costs, complicated processes, and extended processing cycles. The traditional model manufacturing technology uses the process of removing manufacturing, and the manufacturing of complex structures inside the model cannot be realized by traditional technical means. . 3D printing technology has the advantages of high precision and fast forming, which avoids the above problems; based on the process of additive manufacturing, it can accurately print the internal structure of rocks, which is obviously superior to traditional manufacturing processes in terms of model manufacturing. [0003] Fused deposition (FDM) technology is also called fuse molding. It uses thermoplastic materials. Under the c...
