Design and analysis of equipment intended for the production of prototypes

Abstract

Abstract The article deals with the design of a device working on the principle of Fused Deposition Modeling - FDM and its peripherals. Among the most important performing activities of the designer is the analysis of the proposed model with regard to the strength and the resulting accuracy of the created three-dimensional object. The input requirements that the proposed device should meet were defined. Based on these criteria, a numerical and strength analysis was developed using the FEM finite element method. The simulation was carried out on the basis of the hypothesis of shear stress transformation work, which is among the most accurate for the tough materials used. The analysis monitored and evaluated the deformations in the extreme positions where the largest deformations were expected to occur.
