Development of an optimised pressure sintering route for sinter-based additive manufacturing

Objective

The aim of the project is to develop a pressure sintering route for producing sinter-based AM components (MEX/M and MBJ). To achieve this, a holistic approach will be employed, consisting of debinding, sintering, and post-densification, to produce high performance components within a combined heat treatment.  A methodology will be developed to create a closed porous surface layer through the local addition of sintering additives to which pressure can be applied. Innovative approaches for computational fluid dynamics (CFD) based on the GPU-based Lattice Boltzmann method will be employed to guide this development process. This will produce predictions of sinter distortion and optimal furnace loading with scalability and performance not available until now, enabling more efficient and time-saving implementation of optimisation steps. From the results obtained and the existing expertise in the field of pressure sintering, PVA will develop retrofit kits to adapt existing pressure sintering systems to the requirements of the AM pressure sintering process.
