Currently, several principles of 3D printing are known which procedure have been gradually developed and improved. The most commonly used is the FFF (Fused Filament Fabrication) or FDM (Fused Deposition Modeling) method. The principle of this method is that the filament is fed into the nozzle and the resulting melt is applied on the pad in repeated thin layers until a three-dimensional object of desired shapes and dimensions is created. The materials used for filaments are predominantly polymeric materials differing in their mechanical and thermal properties (e.g.

A small Slovak company is nowadays the only producer of balance weights for automotive sector in Slovakia. Nowadays, the company has 15 employees and is on the market since 1990. The products of this company are used in personal motor cars and small utility vehicles. The products of the company are from zinc with a special anticorrosive surface finishing. This is the reason why the company is looking for a zinc alloy, which could be used in manufacturing of their products.

Contamination of water is a global problem. Among the most frequently occurring contaminants in water are heavy metals such as arsenic, antimony, cadmium, mercury, chromium ions, nickel, lead and others, as well as waste products from various industrial productions. The proposed technology represents highly effective and inexpensive method of removal of such contaminants.

A team of inventors from an established Slovak scientific and research institute and an established Slovak university have developed unique technology of information about the increase of electric charge of water droplets in a cloud. Nowadays, several methods exist for prediction of storms with electric discharges. They mostly use technologies based on evaluation of radar and temperature data. Those that work in the radar mode determine the shape of droplets, which in this case serves as an indicator of presence of an increased amount of electric charge.
