    Common challenge

    Additive Manufacturing (AM) is the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. A major challenge for the industry is to move this emergent technology forward from its prototyping history into a true manufacturing capability. The process has the potential to revolutionise design, production and supply of parts, but exploitation has been limited, especially for AM of metal parts, because the post processing of AM manufactured parts is too costly in terms of time and energy. 

    Main Achievements

    In 2017, the research performed resulted in the definition of the state of art of the different post processing steps and the requirements for integration of post processing. 

    Based on the results in 2017, the focus in 2018 was on the development of the post processing solution (WP2). After finishing Workpackage 1, Design, integration of post processing and 3d metal printing proved to be an IT and interfacing challenge. Each process step has its own, unique requirements, in which data integration of CAD, CAM, scanning and CNC milling is key in creating a flexible post processing procedure. An algortihm was developed, generating a specific machine code, the NC-post. Through this algortihm the CAM NC-code is adjusted by considering the optimal fit and its scanned orientation, resulting in the specific NC post which allows to directly mill the clamped object to its net shape. This algorithm is an universal and flexible post processing solution, fitting most existing CNC machines. 

    In 2018, the partnership succesflly presented the project and results during the RapidPro and Prototype fair, resulting in an increase of targets groups and two extra user cases. 

    The application of the Fast Prototyping Approach resulted in a request for modification of the Application Form. This request was submitted in December 2018.
