    Additive manufacturing technology
    (University of Žilina, 2025) Domaniková, Ivana; Blatnický, Miroslav; Dižo, Ján; Slušňák, Patrik
    The article presents an informative overview on the challenges of additive manufacturing technologies. It highlights various methods and their practical applications. Additive manufacturing offers an innovative approach to producing a wide range of objects by depositing material layer by layer according to a digital model. The article describes the fundamental operating principles, commonly used materials, and key areas in which additive manufacturing is implemented. We will describe the benefits of using this manufacturing method, including product customization, reduced material waste, and shorter production times. Our aim is to acquaint the reader with the technology of additive manufacturing and the principles underlying its operation.

    Návrh kompaktnej dosky plošných spojov pre presné snímanie analógového vstupu
    (University of Žilina, 2025) Bučko, Martin; Samaš, Vladimír; Slušňák, Patrik
    The article deals with the design and implementation of a measurement system intended for accurate detection of linear displacement in the braking mechanism during brake lining testing. The measurement is carried out using the analogue sensor Larm LS501, whose output, due to the mechanical design, utilizes 40% of the available measurement range. The signal from the sensor is converted into digital form using a 16-bit ADS1115 analogue-to-digital converter, which allows obtaining approximately 13,107 measurement increments over a total displacement of 400 mm. The resulting measurement resolution is approximately 0.0305 mm per increment. The system is controlled by an ATmega328P processing unit implemented as an Arduino Nano module, which provides data processing and communication via the I²C interface. The electronic part is realized on a two-layer printed circuit board with dimensions of 90 × 45 mm, which, in addition to the processor and converter, includes power and filtering components, input connectors, and four additional analogue channels available in 10-bit resolution. The proposed solution provides a compact, easily serviceable, and cost-effective system for precise linear displacement measurement in a brake inertia test stand.
