RD1: Manufacture of carbide cutting tools
Presentation
The aim of this demonstrator is to prove the viability of the “3D printing farm” concept for highly demanding ceramic materials such as carbides. To achieve this, we are adapting low-capex (low investment cost) 3D printing technology from the Interreg FabricAr3v project to enable it to process these highly abrasive materials using a hybrid pellet extrusion and machining process. The aim is to offer a reliable industrial solution that is much more agile than traditional processes for the production of tools in small and medium-sized series.
Examples of WC/Co parts printed by material extrusion
Promising initial results:
- 98% relative density after sintering.
- 1250 MPa flexural strength.
Partners
The partners collaborating on this demonstrator are CRIBC (Belgium), Centrale Lille (France), and CNRS (France).
