Description du projet
Une nouvelle voie universelle de post-traitement basée sur le laser
Les méthodes de fabrication additive (FA) entièrement numérisées et basées sur le laser sont tellement polyvalentes qu’elles peuvent être mises en œuvre dans différents secteurs d’activité. La FA est plus économe en énergie et génère moins de déchets que la fabrication conventionnelle. Ces pièces nécessitent toutefois des traitements de surface supplémentaires, susceptibles de consommer de l’énergie et des matériaux, ce qui augmente les coûts et nuit à l’environnement. Dans ce contexte, le projet CLASCO, financé par l’UE, développera un post-traitement universel et numérisé basé sur le laser pour créer en FA des pièces fonctionnalisées de formes complexes. Alors que les pièces complexes seront produites par fusion laser sur lit de poudre, le polissage laser et la micro-structuration de la surface par laser à l’aide de l’interférence laser directe seront combinés dans un système de fabrication unique.
Objectif
In the coming years, the European industry must assume the challenge of adopting clean and climate-neutral industrial value chains, producing sustainable products. Adopting digital systems will radically change the industry with products and services through innovative production processes. In particular, fully digitalised laser-based additive manufacturing methods are very versatile and thus can be implemented in different industries. Furthermore, energy saves against conventional manufacturing and material waste but also by design optimization can be achieved. However, these parts also required of additional surface treatments, which are nowadays energy and material-consuming, increasing costs and harming the environment. In addition, new concepts for increasing the added value of AM parts must be developed, for instance, by producing advanced surface functionalities in critical applications. The main objective of the CLASCO project is to develop a universal and digitalised laser-based post-process route for creating functionalised AM parts with complex shapes.
While the complex parts will be produced by Laser Powder Bed Fusion, Laser polishing and laser surface micro-structuring using Direct Laser Interference Patterning will be combined in a unique manufacturing system. This route will substitute several resource-consuming processes, reducing the environment's negative impact. The implementation will allow substituting standard environmental non-friendly methods and even obtaining a better performance. In addition, different in-line monitoring methods, specifically plasma sensors and infrared cameras will be implemented. In this way, a virtual representation of the process for each part will be possible (digital twin), creating an entirely digitised product. The project's impacts will be analysed to optimise the sustainability of processes and products across the entire life cycle.
