Abstract 4D printing has attracted tremendous interest since its first conceptualization in 2013. derived from the fast growth and interdisciplinary research of smart materials, 3D printer, design. Compared with static objects created by printing, allows a printed structure to change configuration or function time response external stimuli such as temperature, light, water, etc., which makes alive. Herein, material systems used are reviewed, emphasis on mechanisms potential applications....
The three-dimensional (3D) printing of flexible and stretchable materials with smart functions such as shape memory (SM) self-healing (SH) is highly desirable for the development future 4D technology myriad applications, soft actuators, deployable medical devices, electronics. Here, we report a novel ink that can be used 3D stretchable, SM, SH elastomer via UV-light-assisted direct-ink-write printing. An containing urethane diacrylate linear semicrystalline polymer developed...
Abstract Folding is ubiquitous in nature with examples ranging from the formation of cellular components to winged insects. It finds technological applications including packaging solar cells and space structures, deployable biomedical devices self-assembling robots airbags. Here we demonstrate sequential self-folding structures realized by thermal activation spatially-variable patterns that are 3D printed digital shape memory polymers, which materials different behaviors. The time-dependent...

Abstract Recent research using 3D printing to create active structures has added an exciting new dimension technology. After being printed, these active, often composite, materials can change their shape over time; this been termed as 4D printing. In paper, we demonstrate the design and manufacture of composites that take multiple shapes, depending on environmental temperature. This is achieved by layered composite with families memory polymer (SMP) fibers – digital SMPs - different glass...
Abstract The creation of reversibly-actuating components that alter their shapes in a controllable manner response to environmental stimuli is grand challenge active materials, structures, and robotics. Here we demonstrate new reversible shape-changing component design concept enabled by 3D printing two responsive polymers—shape memory polymers hydrogels—in prescribed architectures. This approach uses the swelling hydrogel as driving force for shape change, temperature-dependent modulus...

The available experimental data for the density and viscosity of liquid cadmium, cobalt, gallium, indium, mercury, silicon, thallium, zinc have been critically examined with intention establishing both a standard. All categorized into primary secondary according to quality measurement, technique employed presentation data, as specified by series criteria. proposed standard reference correlations are characterized percent deviations at 95% confidence level 0.6, 2.1, 0.4, 0.5, 2.2, 0.9, 0.7,...
Origami structures are of great interest in microelectronics, soft actuators, mechanical metamaterials, and biomedical devices. Current methods fabricating origami still have several limitations, such as complex material systems or tedious processing steps. We present a simple approach for creating three-dimensional (3D) by the frontal photopolymerization method, which can be easily implemented using commercial projector. The concept our method is based on volume shrinkage during...
Multistable mechanical metamaterials are materials that have multiple stable configurations. The geometrical changes caused by the transition of metamaterial from one state to another, could be exploited obtain multifunctional and programmable materials. As stimulus amplitude is varied, a multistable goes through sequence However, this (which we will call deformation sequence) unpredictable if consists identical unit cells. This paper proposes use small variations in cell geometry...

Self-folding origami is of great interest in current research on functional materials and structures, but there still a challenge to develop simple method create freestanding, reversible, complex structures. This communication provides feasible solution this by developing based the digit light processing technique desolvation-induced self-folding. In new method, flat polymer sheets can be cured field from commercial projector with varying intensity, self-folding process triggered desolvation...
Tensegrity structures with detached struts are naturally suitable for deployable applications, both in terrestrial and outer-space structures, as well morphing devices. Composed of discontinuous continuous cables, such systems only structurally stable when self-stress is induced; otherwise, they lose the original geometrical configuration (while keeping topology) thus can be tightly packed. We exploit this feature by using stimulus responsive polymers to introduce a paradigm creating...
Structures and devices with reversible shape change (RSC) are highly desirable in many applications such as mechanical actuators, soft robotics, artificial muscles. In this paper, we propose to use 3D grayscale printing method create self-folding structures. The pattern was used control the light intensity distribution of a UV projector digital processing printer that same photo irradiation time leads different curing degrees thus crosslinking densities at locations polymer during printing....
Multimaterial polymer printers allow the placement of different material phases within a composite, where some or all materials may exhibit an active response. Utilizing shape memory (SM) behavior at least one phases, composites can be three-dimensional (3D) printed such that they deform from initially flat plate into curved structure. This paper introduces topology optimization approach for finding spatial arrangement polymers (SMPs) passive matrix composite assumes target shape. The...
