CO-REACTIVE MATERIALS AND METHODS OF THREE-DIMENSIONAL PRINTING Russian patent published in 2018 - IPC B29C64/10 B33Y10/00 B33Y70/00 

FIELD: printing.

SUBSTANCE: invention relates to three-dimensional printing methods and co-reactive printing compositions, in particular, to the use of three-dimensional printing compositions containing co-reactive components. Composition for three-dimensional printing includes the first component containing the first connection, having at least two first functional groups, as well as a second component containing a second compound having at least two second functional groups, where the second functional groups can react with the first functional groups. At the same time, at least one of the first functional group and the second functional group includes a saturated functional group. And each of the first and second components has a viscosity at 25 °C and a shear rate of 0.1 s^-1, from 5,000 centipoise (cP) to 5,000,000 cP as measured using an Anton Paar MCR 301 or 302 rheometer with a gap of 1 mm to 2 mm.

EFFECT: technical result of the invention is higher quality of products.
