“…Kanabec et al [3] used 3 rd order Bezier curved surface to calculate the control points based on the continuity conditions and then established the tool path based on the control points. Saito and Miyoshi [4] and Kondo et al [5] used the 3-D measuring data to generate the tool path directly. The generation of the tool path is the final stage before RP machine fabrication of a product.…”

Two sets of optical sources with different laser beam diameter are integrated into a rapid prototyping system for increased machining speed in this research. The smaller laser beam is used to scan the object contour to obtain an accurate machining surface and the larger laser beam is used to quickly scan the inner part of the contour without precision control limitation to save machining time. The fabrication parameters of this system are investigated based on product quality and accuracy of practical implementations. The path planning of the inner part and the outer contour are discussed. The userfriendly man-machine interface is developed using the Visual Basic program.

This study aims to build a triangular-mesh model directly from scanned 3D data points, which then generate the stereolithography (STL) file, thus avoiding the troublesome task of producing a CAD model. Accuracy of the triangular-mesh model is achieved because the pitch between data points is generally very small. In addition, the paper proposes a multi-nozzle path algorithm to increase both spraying efficiency and part accuracy. The processing procedure includes: (1) Establishing the triangular-mesh model from scanned data points, which are retrieved by means of contact-or non-contact type measuring machines as well as developing the algorithm to add the radius of the probe automatically.(2) Equally slicing the triangular-mesh solid model and plan spraying paths. (3) Determining the amount and diameter of nozzles appropriate for each slice to generate multi-nozzle spraying paths.
