Recently, I have been developing some 3D models using a 3D modeling tool. The intention was to ‘print’ these models using the 3D printer that my company recently bought.
As part of the experimentation, I noted the difference between using a solid modeler and a simple 3D editor. With the solid modeler, it is possible to easily perform a Boolean operation like subtraction, for operations like embossing. This is because a solid modeler ‘understands’ solid geometry and fills up gaps created by the intersection of objects. A simple 3D editor only works at a mesh (or triangle) level and hence leaves gaps on performing such an operation.
