3D printing or additive manufacturing is the construction of three-dimensional objects from a model. It can be done in a variety of processes in which material is deposited, joined, or solidified under computer control, with plastics, liquids or powders being fused, typically layer by layer. More than 10 percent of all manufactured products will be 3D printed within 10 years, according to estimates. One research team in this area aims to simultaneously develop new chemistries and new 3D printing techniques to reimagine how plastic automotive parts are designed, manufactured, and recovered at the end of their useful life.
