1.1 Principle of AF

Unlike machining, which involves removing material from a block of material, additive manufacturing encompasses all processes that enable parts to be manufactured not from a block of material, but from raw raw material. Depending on the process, this raw material may be in powder, liquid, paste, sheet or filament form. It is transformed (bonded, solidified, conglomerated or fused) selectively during the manufacturing process, layer by layer, following a digital model to create the part while elaborating the material. By comparison, machining is referred to as subtractive manufacturing.
