3d printing technology is amazing. Just read about 3d printed violin and some interesting project which appeared.
Yes, it is possible that clothes will be part of the future. The future of 3D printing is quite wide, and there are many things that people are already making with a 3D printer. It has been argued that many people, including the US government are already researching the possibilities of using the printer to create a lot of things, and this also include clothes.
3D Printing has many years of being a very productive technology. It is not a technology that has been made for printing, even though it is called 3D printing. It is much more, because it makes objects out of more than hundred different materials, including liquid.
The 3D printing has different processes that ultimately print objects in three dimensions. It is also called additive manufacturing. It easily make these dimensional objects from a digital file. How 3D printed object is created depends on usage of various additive processes. This is because, in such additive process, the objects are created with a method that lays down different successive material layers, and it keeps going until the whole project has been created. Every layer can be interpreted as a horizontally slice thin cross-section of the eventual object.
