● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

General Process of 3D printing
FDM - Fused Deposition Molding
FDM works on an "additive" principle by laying down material in layers.
The model is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle.
The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism
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
