Finally we summarize the current and future applications of 4D printing.Īdvanced polymers have occupied centerstage in material science extending conglomerated benefits leveraging multifaced industrial applications. The basic principle of 4D printing with multi material structure is to create precisely controlled localized internal stress with in a printed construct, which upon subsequent stress release can undergo further 3D shape shifting in a predictable manner In this review, we look into the main factors composing 4D printing technology such as smart materials and design. recently, rapid advances in printing process and materials development for 3D printing have allowed the printing of smart materials or multi-materials designed to change function or shape. In this context ,although similar to 3D Printing technology,4D printing technology adds the fourth dimension of time.4D printing allows a printed structure to change its form or function in time and response to stimuli such as pressure, temperature, wind, water and light. With a great potential to change everything from our daily lives to the global economy, significant advances in 3D printing technology have been made with respect to materials, printers and processes. This isn’t to say that 3D printing will be made obsolete, as one of the largest producers of industrial 3D printers, Markforged, recently announced the closing of a lucrative deal that aims to see its technology produce objects on a scale comparable to regular mass production.D Printing has been recognized as a disruptive technology for future advanced manufacturing system. The team believes that these breakthrough materials could lead to better shock absorption, morphing aeroplane or drone wings, soft robotics and tiny implantable biomedical devices. The materials can be reshaped for a wide variety of purposes and can be temporarily transformed into any deformed shape, and then returned to their original shape on demand when heated. The new ‘metamaterials’ created by the team demonstrate pretty unusual and counterintuitive properties not found in nature, with their stiffness capable of being adjusted more than 100-fold in temperatures between 22 degrees Celsius (room temperature) and 90 degrees Celsius. “We believe this unprecedented interplay of materials science, mechanics and 3D printing will create a new pathway to a wide range of exciting applications that will improve technology, health, safety and quality of life,” said senior author of the study, Howon Lee. Unlike 3D-printed objects, those made in 4D can change shape with environmental conditions such as temperature acting as a trigger, and the fourth dimension – time – allowing objects to change shape. However, a number of new flexible, lightweight materials produced by the Rutgers University team have shown themselves to be even more capable. Its ability to create objects of incredibly intricacy for a multitude of uses – particularly in aerospace and medical sectors – has been heralded as being vital to a number of breakthroughs. In a standard 3D-printed design, an object is built from the ground up using a gradual additive process. New research published to Materials Horizons by a team from Rutgers University has shown that the 3D-printing revolution was just a starting point for what we now call 4D printing. 3D printing has promised a revolution in manufacturing, but 4D printing could usher in something truly extraordinary.
