The article focuses on the subject of 3D printing. 3D printing technology and currently used solutions are described. The materials used in printing with the use of a filament printer and a resin printer are discussed. The fused deposiotion modeling technique and the LCD-based stereolithography. Printing technology were presented. Samples were prepared using 3D modeling software. The software used to make the models is discussed. The designed models were printed on two types of printers, using different model orientations. Printouts were measured several times. The obtained data was analyzed and the conclusions, proposed solutions and possible improvements to 3D printing were presented at the end. The article deals with the subject of the possibility of accelerating 3D prints due to their location, but also the influence of warming up the printer during subsequent prints was checked.

Modern education opens up broad prospects for the use of the Internet and its applications. Global computer network helps us to cross all limits allowed for the development and transfer of knowledge and to stimulate and create personal skills. Time and distance are no longer an obstacle. Recently, it has also been popularized in the use of online tools for professional work and intellectual and to the education at all levels of education. In this way, teachers are able to adapt teaching tools to the students' individual needs. Moreover, the aspects of graphical visualization can be more efficient and interesting for students from previously used resources. This paper presents various methods of the Internet in education, and in particular the use of software to solve advanced problems in the art, for example, to calculate transient states. These tools are not only used for training skills or to solve specific tasks but also to shape attitudes and social behavior.

The article discusses the impact of vertical partition, technology on thermal insulation of the building, and the resulting savings and thermal comfort of residents. The study is carried out as an analysis of three selected design solutions including such materials as: aerated concrete elements, polystyrene, ceramic elements, concrete, mineral plaster. Simulation results of heat transfer in a multi-layered wall, are subjected to a detailed analysis by means of thermal visual methods. The study of existing structures, helped to identify the local point of heat loss by means of infrared technology leading to determination of U-value reduction by 36% in maximum for the described 3 types of structure.
