GIVEN THE SCENARIO IN WHICH THE PLANET FOUND ITSELF DURING THE COVID-19 PANDEMIC, ADDITIVE MANUFACTURING (AM), WHOSE USE IN THE HEALTH AREA HAD BEEN ON THE RISE, ACTED AS A STRONG ALLY IN THE MANUFACTURE OF PPE AND VARIOUS MEDICAL DEVICES, SUCH AS OF MECHANICAL VENTILATORS NEEDED TO TREAT COMPLICATIONS ARISING FROM THE CORONAVIRUS. THUS, THE AIM OF THE STUDY WAS TO PRESENT AM AS A VIABLE MANUFACTURING PROCESS FOR A Y-CONNECTOR FOR MECHANICAL VENTILATORS DUE TO THE DEMAND OF COVID-19 IN A HOSPITAL IN THE CITY OF CAMPINA GRANDE. THIS IS A SCIENTIFIC RESEARCH OF AN APPLIED NATURE AND A QUALITATIVE APPROACH, USING THREE-DIMENSIONAL (3D) TECHNOLOGIES THROUGH CAD/CAM SOFTWARE TO DEVELOP AND OBTAIN A Y CONNECTOR FOR A MECHANICAL VENTILATOR, USED AS AN INTERMEDIARY IN DOUBLE BRANCH BREATHING CIRCUITS, DEVELOPED IN 3D TECHNOLOGIES LABORATORY - LT3D.
