Before we look at the specific controls required in FA, it's worth recalling a few fundamental aspects of additive manufacturing.
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.

Events
Numerous seminars and technical days are held every year on the subject of additive manufacturing. Sessions dedicated to AF are included in major events such as the aerospace show and the industry show. However, the two main national trade shows dedicated entirely to AF are held annually in Lyon:

French manufacturers of FA machines for industry
This list is intended to be as exhaustive as possible. The author apologizes for any unintentional omissions.
FA was launched almost simultaneously in France (July 1984) and the United States (August 1984). However, it was in the USA that it first flourished, thanks to the creation of 3D Sytems by Charles W. Hull. Since then, a...
Standards and norms
For AF to be widely adopted, it is imperative to define a normative framework. Only standards will promote acceptance of AF in the industry.
National standardization groups (UNM 920 for France, ASTM F42 for the USA... and international groups, CEN/TC438 at European level and ISO/TC 261 at world level) are very active in the field of AF. They have managed to work well together, respecting a...
