The global 4D printing market is projected to witness a CAGR of 40.30% during the forecast period to reach a total market size of US$152.782 million by 2022, increasing from US$28.103 million in 2017. 4D printing is an extension of 3D printing technology which allows the customers and end users enhanced efficiency, quality, and performance capabilities over existing manufacturing techniques.
The demand for 4D printing is projected to grow on account of providing extensive choice of product design, better utilization of resources, and making manufacturing processes simpler. However, high initial investment requirement and potential safety hazards are likely to restrict the growth of 4D printing market.
INCREASED PRODUCT DESIGN FREEDOM
4D printing has the ability to offer the state of design freedom. It goes one step beyond the design of static objects by adding dynamics and performance capabilities into the material itself. Further, 4D printing will allow parts to adapt their geometry and structure, on-demand, as forces and requirements change, further increasing material efficiency. Moreover, with 4D printing, the manufacturing processes become even simpler than 3D printing. Extremely simple structures can be printed and then activated by external stimulus to change into complex functional structures and systems.
HIGH INITIAL COST
The major challenge for 4D printing technology is the high initial cost as only few companies are currently involved in its research and development Moreover, the development of this technology requires extremely skilled labor, apart from the sophisticated materials. The most common materials used in 4D printing are shape-memory polymers, which normally require going through five steps to make them into adaptable objects. Apart from this, hydrogels are also used however, they cannot be utilized for rigid structures. The cost of these materials is high and as such high initial investment is required for the development of 4d printing technology.
GLOBAL 4D PRINTING MARKET BY INDUSTRY
