Abstract
An automated method for the generation of curved layer toolpaths is demonstrated to produce 3D printed components with improved aesthetic and structural properties using fused filament fabrication printing. Three case studies are shown, which demonstrate the ability of the G-code generating algorithm to resolve concave and convex structures. The combination of conventionally printed layers and curved layers within a single print is also demonstrated by producing double skin curved layer sandwich structures with static z printed cores. Clear improvements in the surface finish of printed components using curved layer fused filament fabrication are shown visually.
Highlights
Additive layer manufacturing (ALM) is a term describing a variety of methods for constructing components from three-dimensional (3D) model data.[1]
A number of ALM methods make use of a bed of feedstock material on the build platform, which is solidified in selective regions through one of a number of methods
SLA printing requires a photocurable resin, which is exposed to laser light to cross-link the polymer, while SLS printing makes use of a laser to selectively sinter regions of material into a solid structure.[1]. As many of these methods rely on precisely calibrated optical systems to solidify the feedstock material, they exhibit some of the highest resolutions and lowest defect rates available with ALM
