Modifications can be made easily and the size of the 3D sculpt can be changed instantaneously with a single click. This is more useful than you can imagine - depending on the final production material and method, shrinkage occurs when creating a mold from a 3D print - 5 to 6% in the case of a Slush Casting mold. With 3D, we can not only check the actual size of the printed prototype but also increase the 3D model size by 5% before printing again to create the final molds.
