Review on the Advancements to Additive Manufacturing-4D and 5D Printing

3D printing is established additive manufacturing technology in the Industry for quite a time. While the Additive Manufacturing industry is still discovering new applications, new materials, and new 3D printers, research is on for other technologies. 4D printing was started a year ago and recently 5D printing is being thought about and experimented. 4D printing has the ability to change the shape of 3D printed objects over time, which is the 4 dimension. 5D printing has the capability to print in 5 different axes thus printing the layers in any required layers and curves.
