Design Process<\/h2>\n\n\n\n

For my first shape, I tried to replicate the ‘flexible design’ that we saw in class and from this paper: https:\/\/handandmachine.org\/publications\/Extruder_Turtle.pdf. I used their method of adding perpendicular movement to the turtle’s path, and applied that to a sine wave.<\/p>\n\n\n\n

My next design uses the concept of ‘bridging’, where you stretch a single piece of filament across a gap. The way my code works is it first prints out a circle, then creates the bridges one by one. Only some layers have bridges and the number of them changes with each layer. <\/p>\n\n\n\n

My last design was a bit of an accident. I was originally just testing to see if I could create loops with filament in the same way as with clay, but I ended up creating this ring with an interesting surface texture instead. Each of the ‘ridges’ comes from the printer doing a quick z-hop while also increasing the amount of extrusion. I used the functions “set_extrude_rate” and “forward_lift” to create these shapes:<\/p>\n\n\n\n

The first two designs are unique from sliced designs from their use of single filament movements. The third design’s quick changes in extrusion rate and diagonal movements mean that it would not be possible to create with a slicer. <\/p>\n\n\n\n
