STUDY INTERNAL MICROSTRUCTURE BY FUSING FRAGMENTS FOR IMPLEMENTATION OF TECHNOLOGY RAPID PROTOTYPING

 

Purpose. The widespread use of technology «Rapid Prototyping», which is the basic component of the process of laser alloying powder composition is due to rise in price of raw materials, energy , minimizing the time spent on the introduction of new products. The possibilities of this technology through the use of laser technology as a tool to significantly expand the range of materials used, as well as to obtain products with complex geometric configurations . So the developers are issues of productivity and quality of items formed from powder materials. Design/Metodology/approach. In this work shows the author's method aimed at improving the performance of products kochestvennyh derived technology of laser fusion of the powder material. The task was implemented metalograficheskim analysis conducted followed by the results of experimental data using statistical techniques, namely the construction of a mathematical model of continuity of the second order with the subsequent optimization of the response function. Findings. Developed in the paper, the method allows to control quality parameters of the process of laser fusion of the powder material. Thus, the results of the studies cited in this article are of both scientific and practical interest. Originality/value. The author shows the possibility of applying statistical techniques to control the quality parameters of the process of laser fusion of the powder material.

Keywords: continuity, geometric configuration, the internal microstructure, fused fragments.
