“…Tymrak et al 29 found little difference in the mechanical properties of components manufactured on different machines. Many methods for improving the mechanical properties of the components have been suggested, such as the use of curved layers, 30,31 design optimization, 32,33 and process parameter optimization. 18,19,34,35 Material choice is limited by the melting point achievable by the extruder and viscosity during extrusion.…”

“…In FDM the tensile strength of the extruded filaments is much stronger than the fused interfaces between the filaments. If the filaments can be deposited in 3D space instead of being restricted to 2D planes the part strength may be increased substantially (Singamneni et al, 2012). Figure 7 illustrates the difference between an arch-like part made using conventional flat layers and curved layer FDM (CLFDM).…”

Abstract:Additive manufacturing (AM) methods are currently utilised for the manufacture of prototypes and low volume, high cost parts. This is because in most cases the high material costs and low volumetric deposition rates of AM parts result in higher per part cost than traditional manufacturing methods. This paper brings together recent research aimed at improving the economics of AM, in particular Extrusion Freeforming (EF).A new class of machine is described called High Speed Additive Manufacturing (HSAM) in which software, hardware and materials advances are aggregated. HSAM could be cost competitive with injection moulding for medium sized medium quantity parts. A general outline for a HSAM machine and supply chain is provided along with future required research.

“…Singamneni et al [5] evaluated curved layer deposition, with an investigation into toolpath generation for curved layers, and demonstrated improved surface quality and mechanical properties of a curved beam; the compressive load of the curved part under 3-point bending increased by 40% over the traditional 2.5D layered design. Multi-Directional Layered Deposition (MDLD) was explored by Singh et al [6], where overhangs, which typically require support structures, were eliminated through changing the angle of the slicing plane relative to the build surface.…”

Abstract. Fused Deposition Modelling (FDM) is a manufacturing process to build components in a layer-by-layer approach through extrusion of polymers from a movable nozzle, allowing for significantly higher degrees of complexity over machined parts. Current FDM systems typically use actuation provided through a gantry or delta structural layout, operating through depositing successive planar layers in a 2.5D process; it has been shown in numerous studies the bonding between layers has significantly lower strength than the homogeneous material or in-plane properties -an issue which can be mitigated through the deposition of curved layers. This paper compares four differing structural layouts of FDM systems (gantry, delta, Stewart Platform, and arm-based) to identify the key advantages of an arm-based method as the increased workspace and manipulability enabling "Additive Finalisation" of components, and suitability for curved layer FDM. Details are then presented of the open-source implementation and evaluation of a 6 degree-of-freedom arm-based FDM printer at the University of Bristol.
