Abstract: The Fully Dense Freeform Fabrication (FDFF) process utilises an adaptive layering method for predefined sheets and uses slices cut by an abrasive waterjet cutter or laser cutter machine for manufacturing functional parts through smart layer alignment and compatible bonding materials. Under pressure and heat, layers are attached and form a 3D prototype from a fully dense material. This paper presents an integrated alignment and compression bonding mechanism that is functional for a variety of complex parts. It also explores the benefits of using induction heaters to reach the brazing quality layer bonding heat for the metallic parts. Finally, feasible settings for producing functional metallic parts for variety of geometries and materials are presented.
