This paper analyses the role of intellectual capital (IC) as a factor of the financial performance of entrepreneurial firms, which are recognized as the main drivers of economic growth and employment.

The sample consists of 188 business owners from Serbia. The primary data are collected using the questionnaire, while the secondary data come from the annual financial statements of their companies. The elements of IC as independent variables are grouped into three components: human, structural and relational capital; sales revenue and operating profit CAGR (5y) are used as dependent variables, while company size and industry type are used as control variables. Statistical analysis involves factor and regression analyses.

The results reveal that IC components contribute to the long-term financial performance of entrepreneurial firms. Specifically, the following elements have positive effects on financial performance: knowledge of the entrepreneur, process improvement and organisational culture. On the other hand, entrepreneurs’ social skills and tenacity were found to have a negative impact on revenue and operating profit growth, while support from informal networks had a negative effect on the growth of sales revenue.

This study aims to fill a gap in the literature on the impact of IC on the financial performance of entrepreneurial firms.

The impact of the application of hollow structures through variations of infill patterns and their density on the tensile properties was considered. The mechanical properties of the parts have a significant influence on the behavior and reliability of the parts in exploitation.

In this paper, the mechanical properties of the additively manufactured ABS material were investigated depending on the FDM printing parameters, which relate both to process parameters such as printing velocity and layer thickness, but also to coupled influence with the change of specimen orientation, that is raster angle. A standard tensile test was applied so that the specimens were prepared according to the ASTM D638 standard.

The results of the conducted experimental research enable the identification of the optimal choice of printing parameters for additively produced ABS materials with the highest values of strain at break and tensile strength. The significance of the obtained results is reflected in the recommendations for the selection of appropriate combination of process parameters for additive manufacturing of ABS parts using FDM technology.

This paper evaluates influence of FDM printing parameters on the tensile strength of parts and therefore on the reliability of the parts.
