PC of the Future: 3-D Printers

Mechanical Engineers Construct Printer and Create 3D Objects

July 1, 2011

Mechanical engineers designed and constructed a 3D printer that creates real objects of your choice. The printer uses materials like stainless steel, plastic and even cookie dough to create various small objects that can be used for function, decoration or even eaten! The object is designed on a computer, which then communicates with the printer nozzle to apply small amounts of the materials in repeating layers, until a complete object is built. A printer can be built for about 2,300 dollars, or can be ordered online, fully assembled.

WHAT IS INJECTION MOLDING? Injection molding is a process used to shape material into a desired form. This process most often uses plastic, but can use other liquid materials, even molten metals. First, a moldmaker creates a mold of the desired shape from a metal. Then, the liquid material can be forced into that mold, where it cools and solidifies into the end product. This process is used in manufacturing to create an extraordinary variety of items.
