Properties of SLS materials
This page lists the available SLS materials and presents their mechanical properties, as they are relevant for application of design rules.
Polyamide PA12 PA2200
Source EOS
Polyamide PA2200 is the basic material for SLS technology. The property profile of durable white parts made from PA 2200 is very balanced: such parts are characterized by strength, rigidity and good chemical resistance. They are also biocompatible and certified for contact with foodstuffs.
