Metal Additive Manufacturing (MAF) is a very fast growing sector. Today's technologies require a great deal of expertise and very significant investments (~€1M), hindering the adoption of this process. More affordable processes are therefore required. New technologies, based on MIM (Metal Injection Moulding) technology, pave the way for the advent of much cheaper machines (€120k). The objective of the project is to develop a process with an overall investment of less than €30k, making it accessible to very small businesses and FabLabs. To switch from rapid prototyping to additive manufacturing, it is necessary to be able to predict defects in parts and control the process in order to predict the mechanical performance of the parts produced. FabricAr3v responds to this problem by designing a “low-cost” process and developing and validating dedicated simulation tools. The skills to be implemented are varied, making the formation of a cross-border consortium absolutely necessary. Thanks to the association with Sirris, it is compared to existing industrial processes. CRITT-MDTS' expertise in MIM allows it to be adapted for 3D printing. Finally, tools for dimensioning parts that are adapted to the processes will be created through collaboration between the CNRS, Centrale Lille and Cenaero. A training platform hinged around this technology is also being developed. However, the arrival of machines that make it possible to copy any metal structure at low cost will probably lead to a reconsideration of intellectual and industrial property. This renders it necessary to investigate the protection models that are compatible with this evolution. The project draws on the expertise of the University of Mons, the University of Lille and the CNRS.
