3. Controls required in AF
3.1 Raw material
Raw material control mainly concerns powders. However, control of carbon black content and ash content for liquids, phase change temperatures for filaments, flatness, roughness and crimp for foils may also be required.
-
In order to guarantee good repeatability and reproducibility of the manufacturing process, and to obtain parts of good quality (predictable and reproducible), the characteristics of the powders must meet certain criteria, which need to be assessed by means of controls. Ultimately, the results of these checks will provide the correlation between the characteristics of the powder and the material being manufactured. In fact, the characteristics of the material will depend not only on the machine parameters,...

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:
Directory
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...
