“…In this regard, the stiffness of a compliant system can be modified through the implementation of specific cellular arrays in the flexible parts of the system. Tailoring stiffness has become more relevant with the emergence of modern manufacturing processes such as additive manufacturing techniques, capable of fabricating complex topologies and shapes [72][73][74][75]. Some studies [76][77][78] showed how the stiffness in beams can be customized by using different types of cellular structures while obtaining minimum weight designs.…”

Cellular Materials and Topology Optimization use a structured distribution of material to achieve specific mechanical properties. The controlled distribution of material often leads to several advantages including the customization of the resulting mechanical properties; this can be achieved following these two approaches. In this work, a review of these two as approaches used with compliance purposes applied at flexure level is presented. The related literature is assessed with the aim of clarifying how they can be used in tailoring stiffness of flexure elements. Basic concepts needed to understand the fundamental process of each approach are presented. Further, tailoring stiffness is described as an evolutionary process used in compliance applications. Additionally, works that used these approaches to tailor stiffness of flexure elements are described and categorized. Finally, concluding remarks and recommendations to further extend the study of these two approaches in tailoring the stiffness of flexure elements are discussed.

“…However, there are a few problems in the AM process, such as, slow mass production and limited material use, which restrict it in several applications. AM has very selective material applications [18][19][20], since the additive manufactured materials are largely found only as a prototype model [21]. In this regard, the multiple printing head technique has been developed where composite materials can be created using controlled material combinations and properties [12].…”

“…Furthermore, sandwich structure made from a mixture of polymer combinations, such as lightweight interior components for automobiles, has long been believed to be a suitable way to obtain a diversity of material properties for customized items. The outer skin of composite materials made of high-strength material sandwich the inner core of a lightweight material, which is covered with sandwich structures [21]. The inner core is usually made up of a wave structure because of its weight.…”

This work investigated the effects of heat treatment on the tensile behavior of 3D-printed high modules carbon fiber-reinforced composites. The manufacturing of samples with different material combinations using polylactic acid (PLA) reinforced with 9% carbon fiber (PLACF), acrylonitrile butadiene styrene (ABS) reinforced with 9% carbon fiber (ABSCF) were made. This paper addresses the tensile behavior of different structured arrangements at different% of densities between two kinds of filaments. The comparison of the tensile behavior between heat treated and untreated samples. The results showed that heat treatment improves the tensile properties of samples by enhancing the bonding of filament layers and by reducing the porosity content. At all structure specifications, the rectilinear pattern gives higher strength of up to 33% compared with the Archimedean chords pattern. Moreover, there is a limited improvement in the tensile strength and modulus of elasticity values for the samples treated at low heat-treatment temperature. The suggested methodology to evaluate the tensile behavior of the pairs of materials selected is innovative and could be used to examine sandwich designs as an alternative to producing multi-material components using inexpensive materials.
