The present disclosure provides a powder composition for three-dimensional printing, which comprises a first type of polymer particles having a glass transition temperature of less than 80 °C, and a second type of polymer particles having a glass transition temperature of 80 °C or more, the first type of polymer particles and the second type of polymer particles being different from each other and each independently comprising at least one of an initiator, catalyst or accelerator for a free radical polymerization reaction, wherein the powder composition comprises from 1 to 15 wt.% of the first type of polymer particles and from 1 to 25 wt.% of the second type of polymer particles, based on the total weight of the powder composition, and wherein the powder composition further comprises at least one additional type of polymer particles, which differs from the first and second types of polymer particles. Such powder composition 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.

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.
