Research On Manufacturing Method Of Avoiding Collapse In 3D Printing Complex Curved Surface Products Based On Fused Deposition Technology

Fused Deposition Manufacturing Technology 3D printing technology is one of the most widely used 3D printing technology.It has a simple equipment,low cost of economic advantages,so it is very high in the field of 3D printing.But with the development of technology and 3D printing technology is widely used,when used in practice,operator still often encounter products made by Fused Deposition Manufacture produce partial collapse,or the whole cannot print successful,In normal conditions,people are based on experience to propose the solution.When found a quality problem,the components has been finished.it not only wasted the material also delayed people's work plan in this process.Therefore,the paper deeply studies the principle of Fused Deposition Manufacturing process.On this basis,using the 3D printing technology,computer application technology and other related technologies.we studies the collapse deficiencies of 3D printing complex surface products based on Fused Deposition Technology by implement a large number of process experiments to proposed a theoretical basis that how to reduce the collapse deficiencies of complex surface product.The principle of multi-objective optimization is used to reduce the area of the product's inclined plane that is greater than the allowable angle,improve the forming quality and machining efficiency of the components by optimizing layer thickness and forming direction.Finally,by means of computer software technology,we detect the print scheme before printing to discover the printing quality of the component,to predict whether the success of printing It is very important to better popularize the fused deposition process 3D printing technology,reduce the economic cost and improve the quality of the technology.At the same time,it lays a foundation for further research on the synthesis system of detect deficiencies of 3D printing complex surface products based on Fused Deposition Manufacturing Technology.The main research work of the article is as follows:1)The principle of the collapse of the complex surface products produced by the fused deposition process is analyzed The collapse phenomena of three kinds of structural characteristics are summarized,And then make a brief mechanical analysis of it.A set of technological experiment scheme is designed to explore the limit condition of no collapse under the three corresponding characteristics.2)Aiming at the collapse problem of complex curved surface products produced by Fused Deposition Technology,On the basis of obtaining the limit inclination angle of the inclined plane Optimize the forming direction and layer thickness of the complex curved product,It plays an important role in reducing the inclined plane collapse and improving the forming quality and forming efficiency of the products.3)By means of computer application technology,Obtaining geometry information of the STL model of complex curved surface,and providing geometric data of product for optimization calculation;the STL model is layered and visualized by means of OPENGL graphical interface tool Thus,it can play an auxiliary role in adjusting the product process plan and detecting whether the product has the collapse defect.4)According to the principle of fused deposition manufacture and the Limit condition obtained by experiment,A method for detecting several collapse characteristics of complex curved surface products produced by fused deposition manufacturing is proposed,It can be used to judge the forming process plan of the product and check whether the collapse defect will occur,and the development of inclined plane feature collapse detection system has been completed.
