    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.
