SLS - Selective Laser Sintering
An additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal).
The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part.
After each cross-section is scanned, the powder

3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
Basic principles

It is because we have an academic curiosity towards MPVA. We have wondered what kinds of problems, leadership styles and motivation would be occurred in the organization where young-aged groups
