Beschreibung
Zusammenfassung:	Compounds and compositions are provided which are useful in additive printing, particularly additive printing techniques such as stereolithography (SLA), wherein a composition of one or more photocurable compounds, such as a compound with multiple ethylenically unsaturated groups and a compound with multiple thiol groups, is photopolymerized, optionally in the presence of two or more thermocurable compounds which are reactive with one another and are subjected to thermopolymerization, to form a manufactured article in solid form. L'invention concerne des composés et des compositions utiles dans l'impression additive, en particulier dans des techniques d'impression additive telles que la stéréolithographie (SLA). Selon l'invention, une composition d'un ou plusieurs composés photodurcissables, tels qu'un composé comportant de multiples groupes à insaturation éthylénique et un composé comportant de multiples groupes thiol, est photopolymérisée, éventuellement en présence d'au moins deux composés thermodurcissables pouvant réagir entre eux et étant soumis à une thermopolymérisation, afin de former un article manufacturé sous forme solide.
