Beschreibung
Zusammenfassung:	The present disclosure provides a material system for three-dimensional printing, which includes (a) a powder composition comprising polymer particles and (b) a liquid binder comprising a material polymerizable by free radial polymerization and a trivalent phosphorous compound. Such material system enables to prepare articles by 3D printing which have good green body strength and form stability upon curing at elevated temperatures. The final cured three-dimensional articles have mechanical properties, which render them suitable for end use applications.
