Resident 3D-printing expert at Hubs, Robin Brockötter, highlighted how 4D printed textiles will push the boundaries of design and functionality in the fashion industry. The potential benefits of this technology could provide a competitive edge to athletes. Designed to adapt to users' unique foot shape and movement patterns, these shoes will offer a superior fit, cushioning, insulation and breathability. Several researchers and brands including Adidas are currently exploring the development of 4D-printed shoes. Shape-morphing systems would enable designers to craft clothing and accessories that adapt to both environmental factors and the wearer's preferences. "I believe 4D printing could be particularly intriguing in applications where an electric current is applied to the object, instead of heat or light,” said Nordtomme “This is especially relevant for the automotive, aerospace, and maritime industries, where there's a keen interest in manipulating structures for aerodynamic purposes." Beyond that, 4D-printed materials can help develop lightweight, flexible structures for satellites and spacecraft, ultimately lowering the costs and complexity associated with space missions.Īdrian Nordtomme, director of APAPTA LTD, said that the benefits of 4D printing won’t be confined to aerospace, but will also affect other transportation industries. As highlighted by Concordia University research, 4D-printed drone wings, which bend up to 20 degrees in response to stimuli, can significantly improve efficiency. Shape-morphing components can enable aircraft to adapt to various flight conditions, reduce air drag, and enhance performance and fuel efficiency. The aerospace industry stands to benefit greatly from 4D-printing technologies. This technology may prove to be a lifesaver for heart patients who require timely access to medicine. These hydrogels can react to changes in a patient's vitals such as body temperature, pH levels, blood pressure, or the presence of specific enzymes, and release medications when and where they're needed. The impact that this will have on medicine will be monumental."Īs outlined in this research paper, scientists are already developing 4D-printed hydrogels designed for stimuli-responsive and targeted drug delivery. He said, "This technology can be used for controlling the release of a drug in the body with extreme precision. Robert Jones, a manufacturing engineer at Nissha Medical Technologies, is confident that the advantages of 4D printing will extend beyond implants. For instance, doctors could print dental implants that expand and contract to create the perfect fit for a patient's jawbone. With shape-morphing abilities, these implants can potentially adapt to a patient's body over time. This is where 4D printing can make a difference. Here's what they had to say about shape-morphing systems and the industries this technology could potentially transform.Ĭonventional implants often have limitations due to their rigid structures. To gain a better understanding of its potential, we consulted with a range of experts in the additive-manufacturing field. While 4D printing is still in its infancy, it's easy to envision the huge impact it could have on various sectors. Imagine a smart textile that adjusts its breathability based on humidity or a plumbing system that expands or contracts in response to temperature fluctuations. By employing responsive materials that react to external elements like heat, light, moisture, electric current, or pressure, 4D-printed objects can undergo changes in shape or properties. 4D printing-this emerging technology, also known as shape-morphing systems, adds the dimension of time to 3D printing.
