3D printing market’s higher CAGR
According to MarketWatch, “The 3D printing materials market size is estimated to grow from USD 1.5 billion in 2019 to USD 4.5 billion by 2024, at a CAGR of 25% between 2019 and 2024. 3D printing materials are used in different industries such as automotive, aerospace & defense, and healthcare. Metal 3D printing materials are projected to register a higher CAGR, in terms of value and volume, between 2019 and 2024.”
4D printing adopting 3D printing’s multi-material approach.
According to Qi Ge, and scientist from mechanics, mechatronic systems,” a simple and versatile multi-material 3-D printing approach to fabricate highly complex, hybrid 3-D architectures. They then used a self-built digital-light processing multi-material 3-D printer to form hydrogel-polymer hybrid 3-D structures. The team displayed a series of applications including a 3-D printed meniscus, 4-D printed cardiovascular stent and a 3-D printed ionic conductor, as advantages of the approach.”
