... the cost of the filling operation increases with the number of scan line segments, as is the case in numerically controlled machining, layered fabrication and computer graphics applications, then it is desirable to select a direction that minimizes this number. In this paper we provide a method...

...Georges M. Fadel; Chuck Kirschman Rapid prototyping systems are controlled by a computer which uses the CAD representation to build parts according to an additive plane layering process. The computer controls a laser beam or a print head, or any process that leads to the formation of a slice...
