4.  a process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material  This process is call additive manufacturing which is creating an object by creating layer after layer

5.  Price of a 3D printer can range from $400 to close to $60,000  Cost of basic printing material for printing is $50 for a single cartridge

6.  Select or create a design ◦ Using CAD to create your design ◦ Many open source designs available  Send the design to the printer as.STL file  The printing material gets ready ◦ Materials available include rubber, plastics, paper, polyurethane-like materials, metals, and more

7.  The material is dispensed in 100 micron ( or micrometer) layers until the object is completed ◦ This process can take hours to days depending on the size of the object ◦ 100 microns is equivalent to 0.1 millimeters

8.  Multi-material printing  Medical field  Food
