    Design and Additive Manufacturing of a Flat Form Tool
    Rahman, Shahbaz; Bodzás, Sándor; DE--Műszaki Kar
    The focus of this in-depth study is largely on the application of additive manufacturing in the creation of a flat form tool; an integral component utilized in several engineering applications. The study progresses with a holistic approach where each stage lends itself to the more broad-scope objective of reimagining the process of tool production through advancements in 3D printing technologies. Initially, the study embarks upon an in-depth analysis of the flat form tool, from both a constructional and analytical perspective. Essentially, this aspect lays the basis for the forthcoming design stages and the actual production methodologies. Furthermore, this study encircles the creation of CAD models for both the tool and the workpiece. The entire layout procedure enlists sophisticated modelling patterns tailored specifically to enhance precision and maximum functionality to develop models. Thus, paving the path for an efficient production process attuned to accuracy. Following the design phase is the actual operationalization of additive manufacturing of the tool. The Ultimaker 3, 3D printer is pressed into service, using PLA (Polylactic Acid) material, for manufacturing the tool. The Ultimaker Cura Slicer Software has been utilized to transform intricate digital blueprints into precise physical entities, with efficient material usage. Lastly, a finite element analysis (FEA) is performed on the produced tool to gauge its performance amidst operational situations. The results of this evaluation offer vital understanding of the tool’s mechanical idiosyncrasies, thereby aiding the ratification of design selections and corroborating functionalities along with resilience. Overall, this thesis proves conclusively that additive manufacturing holds viability and obvious benefits when it comes to producing tools tailored for unique requirements. Ultimate power of 3D printing in transforming tool production shouldn’t be neglected as it offers flexibility, waste minimization and heightened productivity. The study marks a potential ground breaker in its domain, revealing an all-encompassing mechanism to tool formation and manufacturing. By doing so, this study opens doors to future developments and potential advancements in additive manufacturing application in an extensive spectrum of industries.

    The Geometric Effect on the Tensile Behaviour of an Additive Printed Material
    Kumar, Jatin; Huri, Dávid; DE--Műszaki Kar
    The present thesis investigates the intricate relationship between geometrical changes and rubber-like materials tensile behaviour. Additive manufacturing technology has made fabrication a different game altogether, affording unbelievable freedoms not only in design but also choice of materials. The use of rubber like materials whose mechanical properties are unique in the field of flexible and resilient materials that provide a systematic way of “unravelling the geometric effect” on tense behaviour hold great potentiality. Using additive manufacturing techniques, many similar shape specimen samples but various geometric configurations was produced. These test samples subject to uniaxial tensile capture the material response to mechanical stresses. The post-processed measurements yielded accurate stress strain curves, elucidating the material behaviour in varying load settings. This study will compare stress, strain curves for samples with different geometry. It encompasses a wide array of geometric variables such as the aspect ratio, curvature, and density of infill. Through this study we are able to detect the complex and sometimes non-linear influence of geometrical parameters in a tensile load of an additively manufactured component. This is the reason why outcomes of such study contribute into deepening our basic knowledge about physical science and highlight the fact of how geometry influences tensile behaviour regarding potential additive manufacturing application. The study constitutes an enabler to enhancing the designs and manufacture process in additive manufacturing. Such an insight is of vital importance for use in areas such as soft-robotics prosthetics and flexible electronics as materials deployed within them need a very high degree of flexibility.
