The article presents the development of a laboratory device for producing combined nanofibrous structures using DC electrospinning (DCES), AC electrospinning (ACES), and electrohydrodynamic printing (EHD printing). The objective was to assess the applicability of these techniques for preparing multilayer and hybrid structures and to design a device concept that enables their implementation.Experimental work focused on identifying key parameters influencing process stability and fibre quality. The effects of applied voltage, capillary-to-collector distance were investigated. In addition, simulations of the electric field were carried out to provide a basis for optimising electrode geometry and the arrangement of functional components.Based on experimental data and simulation results, a device concept integrating the three techniques into a single system was proposed. The article describes the configuration of individual modules and their adjustment options. Initial tests are presented, showing the preparation of nanofibrous structures with different morphologies and properties depending on the selected process parameters.The findings indicate that combining DCES, ACES, and EHD printing is suitable for the fabrication of composite nanostructures. The proposed device concept provides a foundation for further development aimed at applications in tissue engineering, functional coatings, and biomedical materials.
