Recent research using 3D printing to create active structures has added an exciting new dimension to 3D printing technology. After being printed, these active, often composite, materials can change their shape over time; this has been termed as 4D printing. In this paper, we demonstrate the design and manufacture of active composites that can take multiple shapes, depending on the environmental...
Abstract Owing to the success of three-dimensional (3D) printing in biomedical applications, latest addition technology is four-dimensional (4D) printing, which has gained tremendous interest since 2012. 4D being considered as an upgradation and extension 3D that includes time a fourth dimension with utilization smart biomaterials, upon application any external stimulus, shape size printed stru...
We describe an approach to print composite polymers in high-resolution three-dimensional (3D) architectures that can be rapidly transformed to a new permanent configuration directly by heating. The permanent shape of a component results from the programmed time evolution of the printed shape upon heating via the design of the architecture and process parameters of a composite consisting of a gl...
Over the past decade, 3D printing technology has been leading manufacturing revolution. A recent development in field of added time as a fourth dimension to obtain 4D parts. fabricated design created by is static, whereas capable altering its shape response environmental factors. The phrase “4D printing” was introduced Tibbits 2013, and since grown popularity. Different smart materials, stimulu...
