W artykule odniesiono się do nowych wyzwań jakie niesie ze sobą trwająca czwarta rewolucja przemysłowa. Pokazane zostały wydzielone obszary technologiczne tworzące Przemysł 4.0. Syntetycznie opisano obszar technologii – druk 3D stanowiący jeden z dynamicznie rozwijających się filarów Przemysłu 4.0. Na wybranych przykładach omówiono wdrożone i zastosowane w zrealizowanych projektach OBRUM sp. z o.o. podzespoły wykonane techniką druku 3D. W podsumowaniu podkreślono wagę problematyki i koniecznych przemian w polskich zakładach przemysłowych i systemie kształcenia.

This article discusses some new challenges posed by the ongoing fourth industrial revolution. The technological areas that make up Industry 4.0 are shown. One of these areas of technology, 3D printing, which is one of the dynamically developing pillars of Industry 4.0, is synthetically described. Examples are given and described of components made in 3D printing technology in the course of OBRUM’s completed projects. The importance of the issues and necessary changes in the Polish industry and education system is accentuated in the summary.

We present the design and first results of a real-time search for transients within the 650 sq. deg. area around the Magellanic Clouds, conducted as part of the OGLE-IV project and aimed at detecting supernovae, novae and other events. The average sampling of about four days from September to May, yielded a detection of 238 transients in 2012/2013 and 2013/2014 seasons. The superb photometric and astrometric quality of the OGLE data allows for numerous applications of the discovered transients. We use this sample to prepare and train a Machine Learning-based automated classifier for early light curves, which distinguishes major classes of transients with more than 80% of correct answers. Spectroscopically classified 49 supernovae Type Ia are used to construct a Hubble Diagram with statistical scatter of about 0.3 mag and fill the least populated region of the redshifts range in the Union sample. We investigate the influence of host galaxy environments on supernovae statistics and find the mean host extinction of AI=0.19±0.10 mag and AV=0.39±0.21 mag based on a subsample of supernovae Type Ia. We show that the positional accuracy of the survey is of the order of 0.5 pixels (0.13'') and that the OGLE-IV Transient Detection System is capable of detecting transients within the nuclei of galaxies. We present a few interesting cases of nuclear transients of unknown type. All data on the OGLE transients are made publicly available to the astronomical community via the OGLE website.
