L'acciaio Inox AISI 316L è una lega a base di ferro resistente alla corrosione.
Il materiale è ideale per oggetti destinati ai consumatori come orologi, gioielli, montature per occhiali, decorazioni ed elementi funzionali nell'elettronica di consumo.
Le doti di resistenza alla corrosione lo rendono adatto agli impianti industriali e al settore Automotive e Aerospace come materiale entry level per l'uso della tecnologia SLS.
Le parti in acciaio inox AISI 316L possono essere lavorate tramite impianti CNC, sottoposte a micropallinatura e lucidati.

[1] Mechanical stability is dependent on geometry (wall height etc.) and application.
[2] Due to the layerwise building, the surface structure depends strongly on the orientation of the surface, for example sloping and curved surfaces exhibit a stair-step effect. The values also depend on the measurement method used. The values quoted here given an indication of what can be expected for vertical surfaces.
