Current additive manufacturing methods present the potential to construct net-shape structures with complicated architectures, thus eliminating the need for multi-step processing and fasteners/joints. Combined with these features is the ability to ascribe material properties at the sub-millimeter scale, inspiring multi-material, functionally graded designs. These features make additive manufacturing an attractive option for composite materials development. In an effort to extend this family of technologies beyond nano-and micro-composites, we explore the additive manufacture of multi-directional composite preforms. This exercise has served to highlight the aspects of additive manufacturing critical to composite and general materials processing, as well as to demonstrate the high fidelity between modeled and additively manufactured structures. Within the scope of composites development, we review the state-of-the-art and discuss challenges facing the broad adoption of additive manufacturing for directionally reinforced composites processing.

“…Recent ideas and advances point in the direction of evolutionary materials that are capable of self-repair and adaptation to changing environmental conditions [21]. A pertinent example are urban water-supply systems where pipes self-adapt the flow capacity in response to local demand fluctuations in a city with evolving population density [20].…”

Transport networks are crucial to the functioning of natural systems and technological infrastructures. For flow networks in many scenarios, such as rivers or blood vessels, acyclic networks (i.e., trees) are optimal structures when assuming time-independent in-and outflow. Dropping this assumption, fluctuations of net flow at source and/or sink nodes may render the pure tree solutions unstable even under a simple local adaptation rule for conductances. Here, we consider tree-like networks under the influence of spatially heterogeneous distribution of fluctuations, where the root of the tree is supplied by a constant source and the leaves at the bottom are equipped with sinks with fluctuating loads. We find that the network divides into two regions characterized by tree-like motifs and stable cycles. The cycles emerge through transcritical bifurcations at a critical amplitude of fluctuation. For a simple network structure, depending on parameters defining the local adaptation, cycles first appear close to the leaves (or root) and then appear closer towards the root (or the leaves). The interaction between topology and dynamics gives rise to complex feedback mechanisms with many open questions in the theory of network dynamics. A general understanding of the dynamics in adaptive transport networks is essential in the study of mammalian vasculature, and adaptive transport networks may find technological applications in self-organizing piping systems.

“…An exciting new direction is the fabrication of objects that, upon printing, can evolve with time due to external stimuli (e.g., electricity, temperature or swelling), which has come to be known as 4D printing [54,55]. Despite the growing catalog of printable materials, its range is still limited, in particular for commercial products.…”

a b s t r a c tThe surge of modern techniques to fabricate structured materials paired with our ever deeper understanding of complex forms of matter present us with the opportunity to make and study dramatically new forms of designed materials and structures. This movement is being fueled by recent and rapid developments in a variety of fields, including soft matter, materials science, computer assisted design and digital fabrication. Here, we present an overview of these recent trends based on a multidisciplinary meeting on Designer Matter that we organized June 22nd-June 24th, 2015, at AMOLF, Amsterdam.
