Over the next couple of weeks we will have a series of guest posts in which we go through the knot conformation models created by the five James Madison University students in the course: Jonathan Gerhard, Gregory Houchins, Kirill Korsak, Taylor Meador, and Patrick Moran. Here is the abstract for the project:
3D Printed Conformations of Knots through 7 Crossings
Knots are embeddings of circles in 3-dimensional space, but they are typically studied in terms of their projections into 2-dimensional space. We can use 3D printing to study knots in a more 3-dimensional way. In this series we present 3D printed conformations of the fifteen knots through seven crossings, including stick, Lissajous, lattice, torus, petal, and pretzel conformations. Constructing a 3D model that is actually printable can challenging; to 3D print the knot conformations through seven crossings, we used a combination of Mathematica, Blender, Tinkercad, Knotplot, SeifertView, and OpenSCAD.
And here is the full set of printed models, where each of the 15 knots through seven crossings is printed in both a standard conformation (in white) and one other interesting conformation (in color, directly below its white counterpart):

Settings: All of these knots were printed on a MakerBot Replicator 2, with various choices of settings depending on the conformation design.
