Nowadays, many industries are involved with weight reduction as a key factor in the design and development of materials and components. Therefore, one of the technologies is employment of Lightweight structures for this purpose. However, these structures present challenges: they need to be light but also safe, durable and easy to maintain. How can this be done? There is a triangle which its apexes show interaction between various processes, namely, the interaction between shape design, base material and manufacturing. The evidence gained from both successes and failures demonstrates that the interaction between these three elements is crucial for successful designs and end products.
