Cover story successful or fail. These prototypes can be produced at a low production quantity, which won’t then cost a company or client significantly more to create modifications to design files on the fly. 3D-printed textiles in fashion Wearable smart fashion is already a significant growth market and was a major topic of discussion at the 10th LOPEC (large- area, organic and printed electronics convention) conference in Munich, Germany this past March. Exhibitors from all over the world had the opportunity to showcase new technologies, products and printed components. Smart textiles were some of the 0prototypes showcased. Smart textiles are wearable articles of clothing that have integrated technologies, which provide an increase to the overall functionality of the garment. The technology incorpor- ated in smart garments can range from chemical, thermal or even electrical. Some familiar forms of these smart textiles consisted of accessory pieces such as jewelry and shoes. File creation of components with woven interlocked polygon patterns for 3D fashion mirror similar chainmail armor-making techniques dating back to medieval times. Although 3D print in the fashion industry is not mainly textiles, some materials and products are being tested to push the limits and proper- ties to create prototypes that emulate similar characteristics of fabrics. With the increased use of 3D printing in the fashion industry, the customization of garments or accessories is more preva- lent. Utilizing 3D technologies within the fashion world caught on like wildfire several years ago with the start of printed accessories to pair with runway looks. Athletic brands such as Reebok and Nike are marketing high-performance, custom- ized footwear made using 3D printing. Research is being done to develop 3D-printed textiles that use thermal technology to regulate the temperature of a gar- ment to provide personal comfort to the user. With the integration of boron nitride (an additive compound often used in cosmetic products) into the fibres of the textiles when printing, the textile gains excellent thermal and chemical stability. There is also research being done to further develop these textiles on a molecular level with nanotechnologies. There are multiple structural forms of boron nitride, each having unique benefits. There has been recent industry dis- cussion and literature released in regards to future expansion of these technologies into textiles that line the floors and walls of buildings to reduce heating and cooling costs. Some 3D-printed textiles can regulate the temperature of a garment are light-up pieces, or garments that incorporate screen displays. Additive manufacturing over the last couple of years has spread into the fashion industry as more materials have been created that contain flexible properties. The practicality of 3D-printed fashion comes down to the comfort of a garment when worn. There is a differentiating line between fashion art and fashion wear. Considerations regarding comfort are usually integrated during two phases of the entire output process. During the digital creation of the garment via CAD software, polygon placement and sizing is critical as the print geometry used to interlock polygons can affect the structure of the printed piece. There is some visual stereotypes associated with 3D-printed runway textiles, from geometric shapes to large protruding accessories. Once upon a time 3D-printed fashion only All photos courtesy of LOPEC convention in Germany @graphicarts Universities such as the Massachusetts Institute of Technol- ogy have done research on the future of inventing fabrics. With the collaboration of multiple faculties from mechanical engineering to fashion design majors, students are discussing what 3D textiles mean for the future. It is safe to say we have come a long way from the creation of the mood rings and necklace glow sticks. With all the research and development being put into the 3D world, ideas are being brought to life not just by large com- panies but also by individuals in their own homes. The future is full of 3D-printed possibilities and will showcase an increase in product development. As if there isn’t already too much choice when purchasing products, the 3D world will open up the ability to customize these products to create one-offs to tap into new markets as samples or test pieces. With the increase of positive thoughts that these technologies can help businesses create from concept to executable products more markets will open their minds further to the idea of using 3D printing as a solution or new process. Natalie Mainville has a background in 3D printing, working as a 3D specialist for The Printing House and teaching 3D print labs at Ryerson University. She has attended conferences in Toronto as well as internationally at Universities in Ghent in Belgium, and Utrecht in The Netherlands. GRAPHIC ARTS MAGAZINE | October 2018 | 23
