A group of inventions relates to biotechnology. Disclosed are a printing head and a printing device with fabric spheroids. The printing head includes a system of channels containing input and output channels, upper and lower channels for separation of nutrient medium, as well as a channel for a supporting plunger. Inlet channel has diameter providing movement of spheroid on it only by one. Output channel has diameter not less than diameter of inlet channel, includes input hole for input of printing tool and outlet hole for output of spheroids. Separation channels are made with possibility of connection of nutrient removal device with outlet channel through system of microchannels. Device includes a printing head, a device for feeding spheroids with a nutrient medium into an inlet channel, a device for removal of nutrient medium, a supporting plunger, a printing tool, a system for recording position of the spheroid in the output channel and a computing device for control. Inventions provide higher accuracy of positioning of spheroid on printed surface, improved quality of production of three-dimensional structures and faster printing.
