4d printing is a new technology which is in its developing stage where scientists are trying to get a self assembled product in real time. 4d printing is combination of 3d printing and a feature that a material can assemble into a desired shape on its own with some stimulus, stimulus being a vibration, temperature changes in the environment etc. This is a very interesting way of creating things. It can also be custom made like toys for children which is fun to do like creating a spider man toy in green and superman toy in black and white and a batman toy in red and blue. Imagine a toy moving without any motors or battery, how cool would that be!.
This is useful in manufacturing processes where assembling a complex part may be tedious, time consuming, and labour intensive process. This eliminates this limitations as it does this by folding, bending etc. as it is programmed to do so. Now you might think how is this possible?. This is not possible by actual programming through coding. It’s programmed in its molecular level while it is manufactured using 3d printing process.
It can also be used to scare someone in the dark when a doll moves by itself just like in the movies Annabelle.
