Fig. 4From: The role of 3D technology in the practical education of congenital coarctation and its treatment—a feasibility pilot studyThe 3D printed hands-on training tool (HOSTT) assembly for practical training of CoA surgery. The bony thorax was manufactured by FFF and the aorta phantom was manufactured from an elastic resin by SLA. Alligator clips hold the both 3D-printed models in place. The model of the bony thorax was modified after additive manufacturing, by heating at the 3rd intercostal space with a heat gun. Thus the space required for the surgery was createdBack to article page
