Technological watch

The present invention belongs to the technical field of biomedical engineering. Disclosed are a volumetric three-dimensional bio-printing apparatus and bio-printing method. The volumetric three-dimensional bio-printing apparatus comprises a medium chamber, a rotation unit, a focusing unit and a control unit, wherein the medium chamber is used for accommodating bioink; the rotation unit is used for bearing the medium chamber and rotating same at a preset speed; the focusing unit is used for enabling an energy beam to pass through at least one preset position in the medium chamber, such that preset positions of the bioink can be cured to form three-dimensional objects at the same time; and the control unit is electrically connected to the rotation unit and the focusing unit, respectively. The volumetric three-dimensional bio-printing apparatus provided in the present invention realizes the characteristics of simultaneously forming three-dimensional objects, preventing biological pollution, realizing a high printing speed, being applicable to the printing of complex structures, forming three-dimensional objects, which have smooth surfaces and have resolutions of 50 ?m, and being suitable for industrial popularization and application.
