Abstract
Adaptive slicing in Rapid Prototyping Manufacturing (RPM) allows selection of the layer thickness based on the desired quality of the final product. This paper proposes an improved adaptive direct slicing technique for rapid prototyping where Computer Aided Design (CAD) model is directly expressed in standard Initial Graphics Exchange Specification (IGES) format. Using the developed computational platform, the IGES file is sliced based on the user defined allowable surface error factor and the layer thickness range of the RP machine. The total surface error is computed with the developed error function to verify slicing efficiency with respect to cost, production time and accuracy. Variety of experiments was conducted to find the accuracy of the developed procedure and the cost effective surface error factor.
