Disclosed are a method and an apparatus for manufacturing a radiation intensity bolus. The method comprises the steps of: (a) calculating, by a radiotherapy treatment planning unit, a received 3D radiation dose distribution, planning a bolus to be manufactured, and outputting radiation intensity modulation information； (b) receiving, by a bolus design unit, the radiation intensity modulation information, generating a conversion file for manufacturing bolus, and outputting information about a 3D structure of the bolus to be manufactured； (c) receiving, by a bolus manufacturing unit, the conversion file for manufacturing bolus, verifying a type, location, and size of the bolus to be manufactured, sending the verified data to a 3D printer, and manufacturing the bolus； and (d) obtaining, by an accuracy verification unit, information about a 3D structure of the manufactured bolus and evaluating manufacturing accuracy by comparing the information about the 3D structure of the manufactured bolus with the information about the planned bolus.
