Military Engineering Services (MES)

Consider the following statements:

  1. Recently, Indian Army’s Military Engineering Services (MES) constructed two houses using 3D Rapid Construction Technology.
  2. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes.
  3. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.
