Settings: Makerbot Replicator 2 on .3mm/low with custom knot slicing settings. The knot requires almost no support material if you print it end-up instead of flat on its side.
Technical notes, spiral flavor: It isn't known whether or not all knots have a spiral representation. As of the time of this blog post we know that eight of the fifteen knots through seven crossings are spiral. The spiral notation S(n,k,(....)) denotes that the knot can be represented as an n-strand braid periodic knot with k repetitions and over/under spiral pattern determined by the vector in parentheses.
- 3_1 is a torus knot so has two spiral representations: S(2,3,(1)) and S(3,2,(1,1))
- 4_1 has spiral representation S(3,2,(1,1))
- 5_1 is a torus knot so has two spiral representations: S(2,5,(1)) and S(5,2,(1,1,1,1))
- 6_2 has spiral representation S(5,2,(1,1,1,-1))
- 6_3 has spiral representation S(5,2,(1,1,-1,-1))
- 7_1 is a torus knot so has two spiral representations: S(2,7,(1)) and S(7,2,(1,1,1,1,1,1))
- 7_6 has spiral representation S(5,2,(1,1,-1,1))
- 7_7 has spiral representation S(5,2,(1,-1,-1,1))
