The Invention Of The Printing Press

Good Essays

The printing press invented by German goldsmith Johann Gutenberg in 1448 has been called one of the most important inventions in the history of humankind. When compared to the standard printing methods of the day, the printing press revolutionized how mass quantities of books were printed. The enlightenment in Europe and America were greatly affected by its invention. From its beginnings in 1448 the printer has evolved into today 's modern laser jet printers. One printer that most people don 't think of is the 3D printer. While the idea has been around for years, just recently within the past 10 years has it really taken off. The 3d printer uses the concept of printing a picture of a part, but instead of creating a 2D image, it prints a 3D object. This is a revolutionary manufacturing method that has changed how companies do business. Like the printing press, the modern 3D printer has the chance to revolutionize the world. While it may face challenges, the 3D printer has an enormous upside and a variety of uses.
3D printing is a foreign concept to many people, especially those not in the engineering field. Before I go into why it will revolutionize the world, we must first understand how it works. There are 4 basic types of printing: Extrusion, Granular, Steriolithography, Bio-printing. To start I will explain extrusion. Extrusion printing starts by taking a 3D Computer Aided Drafted (CAD) file and divide it into very small slices. The most common file is in the .STL file
