The present invention provides a full-automatic cell production line, comprising a culture region and an operation region. The culture region comprises a B-stage platform body, and the B-stage platform body comprises a culture area, a refrigeration area, and a robot provided with a motion track. The motion track of the robot is linearly arranged. The culture area, the refrigeration area, and a manual delivery window all surround the track, and are all located in the operation region of the robot. The operation region is integrated with a liquid storage table, a cell factory liquid changing device, and a centrifugal bottle liquid changing device. The delivery window is used between the culture region and the operation region to deliver a material. The technical solution of the present invention is mainly used for full-automatic batch production of cells.

The present disclosure provides a method for photo-curing 4D printing of a multi-layer structure with an adjustable shape recovery speed, and a multi-layer structure printed thereby. The multi-layer structure printed by the method for photo-curing 4D printing of the multi-layer structure with the adjustable shape recovery speed includes a plurality of deformation units sequentially connected in series, and each of the plurality of the deformation units includes two slow layers, a fast layer, and a transition layer; and the fast layer is arranged between the two slow layers, and the transition layer is arranged between at least one of the two slow layers and the fast layer. In the present disclosure, a low cross-linking layer is doped with a nanocarbon light-absorbing material to solve the problem that the low cross-linking layer is prone to over-curing when a high cross-linking layer is printed on the low cross-linking layer.

The present invention relates to the field of 4D printing, and particularly to an electro-responsive folding and unfolding composite material for 4D printing, a method for manufacturing the same, and a method for regulating shape memory behavior thereof. In the process of layer-by-layer printing, conductive layers are embedded into a pre-designed shape memory polymer matrix through spray-coating and laser-irradiation nano-fusion welding, to manufacture a folding and unfolding structure with electro-responsive shape memory behavior. The distribution and range of heat affected zones in the electro-responsive shape memory folding and unfolding structure are controlled by adjusting the number of electric heating layers energized and the value of an energizing voltage. The speed of shape recovery and the degree of shape recovery of the structure are regulated according to a magnitude relationship between a shape recovery force Fand a resistance Fto shape recovery of the structure.
