description	The present disclosure provides a material system for three-dimensional printing, which includes (a) a liquid binder comprising a material polymerizable by free radical polymerization and (b) a powder composition comprising a first type of polymer particles and a second type of polymer particles, which are different from each other and each comprise an initiator for a free radical polymerization reaction, wherein the first type of polymer particles are swellable or dissolvable in the liquid binder at room temperature and thereby release contained initiator for a first free radical polymerization of the polymerizable material, and wherein the second type of polymer particles release additional initiator upon contact with the liquid binder at elevated temperatures above 40°C for a further radical polymerization of the polymerizable material. 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. La présente divulgation concerne un système de matériau pour une impression en trois dimensions, qui comprend (a) un liant liquide comprenant un matériau polymérisable par polymérisation radicalaire et (b) une composition de poudre comprenant un premier type de particules polymères et un second type de particules polymères, qui sont différents l'un de l'autre et comprennent chacun un initiateur pour une réaction de polymérisation radicalaire, le premier type de particules polymères pouvant gonfler ou se dissoudre dans le liant liquide à température ambiante et ainsi libérer l'initiateur contenu pour une première polymérisation radicalaire du matériau polymérisable, et le second type de particules polymères libérant un initiateur supplémentaire au contact du liant liquide à des températures élevées supérieures à 40 °C pour une autre polymérisation radicalaire du matériau polymérisable. Un tel système de matériau permet de préparer des articles par impression 3D qui présentent une bonne résistance d'ébauche crue et une bonne stabilité de forme après durcissement à des températures élevées. Les articles tridimensionnels durcis finaux présentent des propriétés mécaniques qui les rendent appropriés pour des applications dans des utilisations finales.
