FIELD: physics.
SUBSTANCE: proposed composition comprises meta-acrylic oligomers and initiating system. Said meta-acrylic oligomers represent a mix of multifunctional meta-acrylic derivatives of hydroxyl-containing oligo-ether(meta)-acrylates, while photoinitiator comprises compounds from the group of α-hydroxy ketones, α-amino ketones, α-di-ketones, aryl-alkil ketals, alkoxy aryal alkyl phosphine oxides.
EFFECT: higher efficiency of laser stereolithography units.
