Abstract
To use Additive Manufacturing (AM) to its full potential, besides an expert user, a good Computer-Aided Manufacturing (CAM) tool for process planning is paramount. The main AM process planning steps are: build setup, responsible for defining orientation, positioning, and scaling of the 3D model; slicing; support calculation; filling and machine data generation. Several decisions that will affect cost, quality, and manufacturing time need to be taken in this process. The AM and tooling group (NUFER) has been developing a CAM for AM called Rapid Prototyping Process Planning (RP3) for over a decade, and it is now in its third generation. The main objective is to develop research to improve AM process planning. RP3 can work with the main AM categories and offers complete control of the methods to perform the process planning tasks. This paper presents the main features and some of the late implementation of RP3. The highlighted contributions are an optimal slicing method, mesh topology, tool-path optimization, and many filling strategies to generate porous structures. As it has been developed as a modular, easy-to-adapt software, different methods for the same task can be designed and easily integrated, becoming an ideal framework for research and development in this area.
