Application of LOM for freeform architecture

Additive Manufacturing (AM) techniques have been applied to many fields. Among them, the Fused Deposition Method (FDM) has been utilized in construction application with concrete paste instead of plastic resin. This paper presents feasibility study of applying Laminated Object Manufacturing (LOM) process especially for freeform architecture. We developed 3D printer of LOM technique equipped with sloped cutting capability. In that way, the surface quality can be improved even with thick laminated sheets. The feasibility of this novel approach was proved through building a freeform bench, and comparing its building time and manufactured freeform surface quality.
