What is 3D-Printing?

subtracive 3D printing or Additive manufacturing is a process of making a three dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes)

An Incredible New Technique For 3-D Printing Metal In Midair

We can 3-D print myriad plastic goods, fabric for apparel, burritos, candy, and perhaps in the not-so-distant future, human organs. Metal–the material that forms the skeleton of any city, building, or car–has been less accessible. Now, a collaboration between Dutch designer Joris Laarman and software company Autodesk has yielded something groundbreaking: an affordable technique for printing large metal structures, called MX3D-Metal
