Zusammenfassung:	Radiation curable compositions for additive fabrication processes, the components cured therefrom, and their use in particle image velocimetry testing methods are described and claimed herein. Such compositions include compounds which induce free-radical polymerization, optionally compounds which induce cationic polymerization, a filler constituent, and a light absorbing component, wherein the compositions are configured to possess certain absorbance values at wavelengths commonly utilized in particle image velocimetry testing. In another embodiment, the compositions include a fluoroantimony-modified compound. Such compositions may be used in particle imaging velocimetry testing methods, wherein the test object utilized is created via additive fabrication and is of a substantially homogeneous construction. L'invention concerne des compositions durcissables par rayonnement pour des procédés d'impression 3D, les éléments ainsi durcis, et leur utilisation dans des procédés de test de vélocimétrie par images de particules. Ces compositions comprennent des composés qui induisent une polymérisation par radicaux libres, éventuellement des composés qui induisent une polymérisation par cations, un constituant de charge et une composante d'absorption de lumière, les compositions étant conçues de manière à posséder certaines valeurs d'absorbance à des longueurs d'onde couramment utilisées dans les tests de vélocimétrie par images de particules. Dans un autre mode de réalisation, les compositions incluent un composé modifié par de l'acide fluoroantimonique. Ces compositions peuvent être employées dans des procédés de test de vélocimétrie par imagerie de particules, l'objet de test utilisé étant créé par impression 3D et ayant une construction sensiblement homogène.
