ABSTRACT
This chapter deals with Additive Manufacturing processes utilizing sheet lamination processes in terms of its variants; laminated object manufacturing including its process description, materials, process variants, advantages, limitations and applications; ultrasonic consolidation including its basic principles, advantages, limitations and applications; and design and quality aspects. Sheet lamination has mainly two popular variants, i.e. laminated object manufacturing (LOM) and ultrasonic consolidation. The raw material used in LOM was copier paper which is coated with thermally activated adhesive on one side. A feed roll is used to enable movement of a layer sheet material adhesively coated from one side in the build area. Being a solid state process, ultrasonic additive manufacturing has several benefits over other additive manufacturing (AM) processes. Most of the metallic raw material-based AM systems, i.e. metal AM modellers, basically work at a temperature near to or above the melting point temperature of materials, which leads to poor mechanical properties.
