Plastic doodling

Heat-extruding plastic strands and drawing them in 3D is one of the great new technologies we have. There are already several competing platforms; one of the high-profile ones is 3Doodler.

Lord knows how many different things this can be used for... But as usual one of those which interests me most is the fine art application. And I've already seen several different drawings/sculptures which I thought actually was mighty fine fine art.
Some of it from Rachel Goldsmith, she is a really good artist. (And she is not afraid of work.) Here is a 3Doodler feature article on her.
