Mesh Repair for 3D Printing
The mesh of a 3D model is made up of the vertices, edges, and faces that describe the shape of the object. Having a mesh with no holes, also known as a watertight mesh, is one of the critical steps to successfully 3D printing an object.
There are a number of different mesh repair programs available-some cost, other are free. Netfabb is one of the popular free mesh repair software.
