In this episode of STEM Revolution, we explore three-dimensional printing– a subcategory of additive manufacturing.  There are many types of three-dimensional printing.  A few examples are ceramic, stainless steel and laser additive manufacturing.  Three-dimensional printing wastes very few resources because unused materials can be recollected and used again.  It also allows users to produce personalized designs.  This is especially useful in the medical field and the creation of prosthetics.  Three-dimensional printing is being used in countless areas, such as the aerospace, automotive and biomedical industries.  Despite the large energy cost, three-dimensional printing has the ability to revolutionize our world because of the incredible flexibility it allows.

The following podcast takes on the form of an episode of a talk show called Science Today.  In the episode, two specialists in the field of nanotechnology are interviewed about methods of microfluidics and MEMS development.  Microfluidics deals with the behavior, control, and manipulation of fluids on a nanometer scale.  The importance of these technologies lies in the evolution of healthcare, specifically with the development of point-of-care diagnostics.  MEMS stand for microelectromechanical systems; they are small devices that integrate mechanical and electrical components.  Photolithography is one fabrication method of a MEMS device, as you can see illustrated in the graphic above.
