Evaluation of attenuation of envelopes produced in a 3D printer for measurements with dose calibrator

Due to the increase in procedures performed at the Nuclear Medicine Services (NMS), concern about the perfect functioning of the dose calibrators used daily became inevitable. The safe, efficient and effective practice of using the equipment involves the integration of several processes. The objective is the design and development of new envelopes through prototyping using a 3D printer. The materials chosen were PLA and ABS. Accuracy and accuracy tests were performed by varying the printing parameters and the dimensions of the wrapper. The results showed that it is possible to customize the wrappers, improving the results and reducing the uncertainties in the quality control of this equipment
