    Analysis and Testing of 3D models and infills
    Gillani, Syed Musa Hassan; Balogh, Gábor; DE--Műszaki Kar
    In the thesis work, you will be learning about the general effects of Infills. Measurements of each infill such as the general stress and strain have been calculated. Anycubic Kobra 3D printer and Anycubic 3D PLA filament are used for the tests. Furthermore, each infill in the software Ultimaker Cura has been used. Ever since the start additive manufacturing has faced many problems. Some of them include an overhang layer, materials not bonding together properly, and not enough knowledge of the infills and the effects, such problems affect the print quality and have increased defects. The main purpose of this thesis is to understand the effects of each infill where they can be distributed and used in different objects. This can help us reduce the amount of material we use and, in some cases, infills can also reduce the time taken for something to manufacture. The 3D printing technologies with defined infills and uses can expand easily, and such infills can further be integrated into multiple software and help in part optimization. To understand the effect properly, I designed 2 Tests with different properties. The properties included layer heights, wall layer counts, infill density, and top and bottom layer thicknesses. These properties were changed for the tests and the results were observed for differences. After reducing the layer counts and allowing the infill to have more space in the test sample the results were observed. A tensile testing machine with an integrated optical image camera to measure the accurate strength and strain of the materials was used. The final results were compared and the infill effect. The effect of walls was also observed in each test where reducing the wall count more space was available for the infills and a larger difference with results completely dependent on the infills was observed.

    Designing a 3D printer
    Egbi, Daniel Bofa-Okim; Nemes, Dániel; DE--Műszaki Kar
    This thesis investigates the theoretical development of a 3D printer with exceptional accuracy, with a specific emphasis on virtual modelling, simulation, and optimisation methods. The suggested printer is designed to overcome the inherent difficulties of traditional 3D printing, with the goal of achieving unsurpassed precision in the creation of complex three-dimensional objects.The research commences by conducting a thorough examination of current 3D printing technologies, with the aim of identifying their constraints and potential areas for enhancement. Using sophisticated modelling tools, the thesis introduces an innovative conceptual design to improve accuracy and address typical printing problems.In addition, the conceptual design is situated within the wider scope of additive manufacturing, investigating potential uses in several sectors like medicine, aerospace, aviation, and mass customisation. The theoretical framework outlined in this thesis provides a roadmap for future academics and engineers aiming to transform these principles into physical technology.Ultimately, this research introduces an innovative and original blueprint for a 3D printer that achieves exceptional accuracy, thereby paving the way for progress in the field of additive manufacturing. The provided theoretical framework provides a clear plan for practical applications, hence creating new opportunities for precise engineering in three-dimensional printing.
