Three-dimensional printing is a method of converting a virtual 3D model into a physical object. 3D printing is a category of rapid prototyping technology. 3D printers typically work by 'printing' successive layers on top of the previous to build up a three dimensional object. 3D printers are generally faster, more affordable and easier to use ...
Later developments in printing technology include the movable type invented by Bi Sheng around 1040 [4] [5] and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern ...
The global spread of the printing press began with the invention of the printing press with movable type by Johannes Gutenberg in Mainz, Germany c. 1439. [1] Western printing technology was adopted in all world regions by the end of the 19th century, displacing the manuscript and block printing.

A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink.It marked a dramatic improvement on earlier printing methods in which the cloth, paper, or other medium was brushed or rubbed repeatedly to achieve the transfer of ink and accelerated the process.
The art of printing goes back to around A. D. 175, where it was employed by the Chinese, who cut impressions into blocks of wood, applied ink, laid paper over the block and pressed the two together, leaving the inked impression on the paper. This crude method of printing took root in other parts of the world, but didn't change much until the 1100s.
Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. [2]
The world's first movable type printing technology for paper books was made of porcelain materials and was invented around 1040 AD in China during the Northern Song dynasty by the inventor Bi Sheng (990–1051). [1]
