Additive Manufacturing (AM) represents a maturing collection of production technologies also known as rapid prototyping, manufacturing and three-dimensional printing. One the most promising aspects AM is possibility to create highly complex geometries. Despite growing body knowledge concerning technological challenges, there lack methods that allow designers effectively deal with new possibilities. This article presents literature survey on impact can have design. The was focused...

Microbes offer designers opportunities to endow artefacts with environmental sensing and adapting abilities, unique expressions. However, microbe-embedded present a challenge of temporal dissonance, reflected by "time lag" typically experienced humans in noticing the gradual minute shifts microbial metabolism. This could compromise fluency interactions may hinder timely attending microbes living artefacts. In addressing this challenge, we introduce Cyano-chromic Interface, which...

Abstract Durable interfacing of hard and soft materials is a major design challenge caused by the ensuing stress concentrations. In nature, soft-hard interfaces exhibit remarkable mechanical performance, with failures rarely happening at interface. Here, we mimic strategies observed in nature to efficient interfaces. We base our geometrical designs on triply periodic minimal surfaces (i.e., Octo, Diamond, Gyroid), collagen-like triple helices, randomly distributed particles. A combination...

3D printing techniques such as Fused Deposition Modeling (FDM) have enabled the fabrication of complex geometry quickly and cheaply. Objects are produced by filling (a portion of) 2D polygons consecutive layers with contour-parallel extrusion toolpaths. Uniform width toolpaths consisting inward offsets from outline produce over- underfill regions in center shape, which especially detrimental to mechanical performance thin parts. In order fill shapes arbitrary diameter densely require...

Biomimetic composites are usually made by combining hard and soft phases using, for example, multi-material additive manufacturing (AM). Like other fabrication methods, AM techniques limited the resolution of device, hence, setting a minimum length scale. The effects this scale on performance hard-soft not well understood. Here, we studied how affects fracture toughness behavior single-edge notched specimens using random, semi-random, ordered arrangements with five different ratios to...

Abstract Lattice structures have been widely used in various applications of additive manufacturing due to its superior physical properties. If modeled by triangular meshes, a lattice structure with huge number struts would consume massive memory.
