Abstract
Fused Deposition Modeling (FDM) is an extrusion based additive manufactur-
ing (AM) process in which thermoplastic material is extruded through a nozzle.
The nozzle deposits material along a two-dimensional path to create a layer. Suc-
cessive layers are stacked together to create a three-dimensional object. Although
initially developed for rapid prototyping, advances in FDM technology have rapidly
increased the breadth of application. However, the FDM process has inherit disad-
vantages such as poor surface nish (commonly referred to as stair stepping), severe
anisotropic mechanical properties, and increased build time for higher resolution
parts. All of which are a result of the layer by layer manufacturing process. To
remedy these issues, Curved Layer Fused Deposition Modeling (CLFDM) o ers a
new building paradigm for FDM, where material is deposited in curved, non-planar,
layers. The purpose of this paper is to implement a curved layer toolpath genera-
tion algorithm and quantify the bene ts that curved layered methodology has over
traditional planar layers.
