Research And Implementation Of Task Management Platform For Desktop 3D Printing

3D Rapid Prototyping,also known as 3D Printing Technology,has been developing quickly and widely applied to many fields,recognized as the important symbol for the Third Industrial Revolution.“Made in China 2025” has particularly highlighted the importance of 3D Printing Technology.Due to the advantage of its low price and cost and easy operation,Desktop 3D Printing has been widely adopted in the fields of industrial design,mould manufacturing and cultural innovation.Desktop 3D Printing majorly targets the public users with its features of various types,wide distribution and high administration.With the purpose of utilizing the Desktop 3D Printing resource of their owners in a wide environment and providing a better service interface for the uses with demand of processing 3D Printing,this paper studies the management model based on the 3D Printing tast and resource and designs a corresponding management and service platform.Major content are listed as follows:(1)The paper analyzes and designs the demand of management platform focusing on the demand of users and the system.The analysis of the demand of users is based on three perspectives of printing resource owners,printing resource consumers and platform managers.The demand of users forms the demand of the system.The paper later designs a management platform structure based on the above two demands and the features of 3D Printing,studies the systematic structure,functional structure and control model of management platform and designs the major functional modules of the database.(2)The paper researches into the task distribution methods of 3D Printing.The paper applies the concepts of distributed management,combinatorial auction and tendering and bidding into the order task distribution of 3D Printing,designs a distribution model based on tendering and bidding and divides the order task distribution into several procedures such as task division,resource match and task issue,affirmance of the bid and evaluation of the bid as well as tendering and bidding,and the task distribution evaluation.The model also introduces and improves genetic algorithm to evaluate the bid,selects the best combination with lowest cost and distributes the task to its corresponding printer resource owners.The paper adopts the actual examples to analyze the methods in a simulation experiments and prove the effectiveness of the methods.(3)The paper explores the task dispatching methods.A task dispatching method suiting technical and artistic features of 3D printing is designed by probing into the dispatch of printing tasks within the 3D printing workshops of printing resource owners,combing the features of once-forming and multiple types of tasks of 3D Printing tasks and aiming at reducing the processing time and cost.The dispatch method is further optimized by Improved Evolutionary Algorithm.The paper adopts the actual examples to prove the effectiveness of the dispatch method.(4)The paper aims to achieve a 3D Printing management platform.Major modules of the platform is achieved by using SSH development framework to construct a developing environment,adopting Mysql to design the database of the platform and combing the functional demand of the platform.Major modules of the platform enables the registry and management of users and resource and the issue,distribution and dispatch of the task.
