Special Issue Information

Dear Colleagues,

Additive Manufacturing (AM) has been regarded as a potentially disruptive and promising method in fabricating various products with specific shapes and performances. However, the current knowledge on the AM process obtained from physical experiments is still quite limited, largely due to the lack of available measurement techniques. The lack of proper control over such processes leads to a significant drop in the quality of the final product. Numerical modelling provides an effective alternative and powerful tool to understand the fundamentals and applications of the AM techniques by providing full-scale particulate information.

To learn how products can be better designed and manufactured via AM, this Special Issue aims to collect the innovative work of AM and corresponding applications to highlight the current and future developments in the field. Both original research and review articles summarizing the state-of-the-art of the numerical modelling work concerning AM are welcome. Topics of particular interest include, but are not limited to, the use numerical modelling to optimize material components and AM processes and the proposal of new concepts and applications. At last, related experimental work on AM is also more than welcome in the current Special Issue.

It is well established that the introduction of additive manufacturing in various domains has produced significant technological leaps due to the advantages over other manufacturing techniques. Furthermore, additive manufacturing allows the design of parts with complex internal structures (e.g., lattice, honeycomb) to achieve lightweight or other mechanical properties. This paper presents a computational model (integrated into a programable algorithm) designed to generate complex internal structures, using tree-like fractals, for components (mechanical parts) whose designs are achievable by additive manufacturing. The computational model is presented in detail, starting from the mathematical definition and the properties of the proposed tree-like fractals. The fractal data are computed and arranged unequivocally using table representations. Based on the fractal data, the structures are generated inside CAD parts (which are given as inputs in the algorithm). The proposed computational method is applied in different case studies to illustrate their functionality. The generated CAD components (with fractal internal structures) are intended for manufacturing (using selective laser melting) and laboratory (mechanical) testing and for finite element analysis, which in turn can validate the use of tree-like fractals as interior structures for mechanical components.
