Title
(EN) OPTICALLY ACTIVE BUILD MATERIALS FOR 3D PRINTING
(FR) MATÉRIAUX DE CONSTRUCTION OPTIQUEMENT ACTIFS POUR IMPRESSION 3D
Abstract
(EN)
uild materials for 3D printing applications are described herein which, in some embodiments, comprise a dye component operable to alter spectral characteristics of the printed part over the course of the build cycle. In some embodiments, for example, the dye component can provide desirable light penetration depth during article printing and sufficient optical clarity during final light curing processes.
(FR)
L'invention concerne des matériaux de construction pour des applications d'impression 3D qui, dans certains modes de réalisation, comprennent un composant colorant utilisable pour modifier les caractéristiques spectrales de la partie imprimée au cours du cycle de construction. Dans certains modes de réalisation, par exemple, le composant colorant peut fournir une profondeur de pénétration de lumière souhaitable pendant l'impression d'article et une clarté optique suffisante pendant des traitements de durcissement à la lumière finaux.
