SOLUTION OF THE PROBLEM OF EQUIPMENT TYPE SELECTION FOR QUICK PROTOTYPING
Introduction. This article is devoted to solve the problem of choosing equipment for rapid prototyping of objects, based on the method of hierarchy analysis. This task is relevant, since with its help is possible to select equipment based on the preferences of the customer, without requiring him to dive into the information area of the subject. It is known that there is a huge number of different technologies that allow you to create a product, without using molds, only due to the 3D model, therefore it is necessary to have a consolidated idea of the availability of all these methods in the modern market. Data and methods. A mathematical model is used to describes the process of choosing priorities among alternatives in a simplified form in order to facilitate data processing. The main criteria are: print speed, print accuracy, maximum size of the finished product, support for multiple colors when printing, and the cost of equipment. To solve the problem, alternatives were also chosen among printing technologies: FDM, DLP, CJP, MJM. Estimates for criteria and alternatives were obtained by interviewing an expert, followed by data processing. The received results. Tests of the used model and algorithms was carried out at the manufacturing enterprises engaged in rapid prototyping and differing in the complexity of manufactured products. FDM equipment with given parameters is the highest priority for small-scale production. Direct alternatives are DLP and MJM. Conclusion. The model can be used to make decisions more efficiently organize the selection and procurement of equipment for rapid prototyping, and make the decision-making process more flexible and efficient.
