What is a 3D printer? • 3D printers are not your average printer • They bear little resemblance to today's document or photo printers, • They can build objects from scratch—or rather, from a CAD or 3D scanner file—out of a variety of materials.
How does it Work? • A typical 3D printer is very much like an inkjet printer operated from a computer • It builds up a 3D model one layer at a time, from the bottom upward, by repeatedly printing over the same area. • The printer creates a model over a period of hours by turning a 3D CAD drawing into lots of two-dimensional, cross-sectional layers • Most 3D printers essentially works by extruding molten thermoplastics (mostly ABS) through a tiny nozzle that it moves around precisely under computer control. • Is not necessarily need to print in 3D with plastic: in theory, you can print objects using any molten material that hardens and sets reasonably quickly • ABS has a whiteish-yellow color in its raw form, but pigments can be added to make it virtually any color
Uses of a 3D Printer • Product Cost Reduction • Marketing Tools • Product Mockups • Competitive Advantage • Medicine/Science
Uses of a 3D Printer - Medicine • A new technique has been created that prints out artificial blood cells • Designed by scientists at Germans' Fraunhofer Institute • The technique involves printing artificial biological molecules with a 3-D inkjet printer, and then zapping the those molecules with a laser that forms the material into the shape of blood vessels. Like real blood vessels, the artificial vessels have two layers and can form complex branching structures.
