ABSTRACT
3D printing is a modern manufacturing technique based on the layer-by-layer deposition of material. The technological conditions of printing are of high importance to the resultant function properties of the manufactured components. Other than the function properties the economical footprint of the latter is also of high importance to manufacturers. Due to this it is highly important to find the optimal printing conditions such that the cost of printing is the lowest without compromise on the functional, and particularly the mechanical, properties of the components. In the present work, multiple different components were produced using different infill densities in order to determine the economical-technical-functional relationship and find the best printing conditions. Based on the obtained results three different optimal choices were formed – 10 %; 50-60 %; 95-100% infill density. Increasing the infill density increases the mechanical properties significantly, but also increases production costs. The choice of an optimal infill density has to be made by the component designer emphasizing either mechanical strength or production costs. An infill density of 50-60 % offers a medium ground between both considered component parameters.
