METHOD FOR MANUFACTURING A DRIVE WITH SHAPE MEMORY EFFECT (SME) Russian patent published in 2023 - IPC B29C64/10 B33Y80/00 F03G7/06 

FIELD: additive technologies.

SUBSTANCE: when manufacturing a drive with a shape memory effect (SME), by 3D printing, a predetermined external and internal structure of the drive is obtained from liquid photopolymer materials with a shape memory effect; moreover, in the 3D printing process, at least one channel is formed in the drive structure to accommodate an electrically conductive element of a predetermined cross-sectional shape, length and direction; and filling at least one channel with liquid metal to create an electrically conductive element. The resulting drive has improved performance due to the ability to create a drive of any predetermined geometric shape with controlled heating from the inside, which provides a purposefully changed process of activating the shape memory effect and a controlled increase in the mechanical load created by a 3D printed drive with a reliable electrically conductive element that does not crack over time, does not wear out, has no restrictions on the number of flexion / extension cycles, and also has the ability to bend in various directions without damage, elongate or shrink, or twist.

EFFECT: improved performance.
