Query: A framework for adaptive width control of dense contour-parallel
  toolpaths in fused deposition modeling   3D printing techniques such as Fused Deposition Modeling (FDM) have enabled
the fabrication of complex geometry quickly and cheaply. High stiffness parts
are produced by filling the 2D polygons of consecutive layers with
contour-parallel extrusion toolpaths. Uniform width toolpaths consisting of
inward offsets from the outline polygons produce over- and underfill regions in
the center of the shape, which are especially detrimental to the mechanical
performance of thin parts. In order to fill shapes with arbitrary diameter
densely the toolpaths require adaptive width. Existing approaches for
generating toolpaths with adaptive width result in a large variation in widths,
which for some hardware systems is difficult to realize accurately. In this
paper we present a framework which supports multiple schemes to generate
toolpaths with adaptive width, by employing a function to decide the number of
beads and their widths. Furthermore, we propose a novel scheme which reduces
extreme bead widths, while limiting the number of altered toolpaths. We
statistically validate the effectiveness of our framework and this novel scheme
on a data set of representative 3D models, and physically validate it by
developing a technique, called back pressure compensation, for off-the-shelf
FDM systems to effectively realize adaptive width.
