Transcript of 3D Printing
(3D print·ing) noun
1. a process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material.
History of 3D Printing
3D printing technology has been around since the 1980s
The first working 3D printer was created in 1984
How does it work?
3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes
What is the printed object made of?
For most personal 3D printers you choose between two types of plastic: acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). Some printers work with just one, other printers work with both.
-ABS is chemical-based and works at slightly higher temperatures.
-PLA is derived from natural sources, such as corn or sugarcane. It’s more rigid and glossy than ABS.
Higher end 3D printers also use brass, ceramic, steel and up to five types of plastic.
