This is a ramp of ABS Filament, 175mm Change Colour Filament (Green to Yellow) printed with dual extrusion in a surround to try get a sense of the medium's ability to change colour vs thickness. Depending on the results there may be some hidden uses for this ability to change colour due to heat.print at .1 layers with spare filament as the surround and ABS Filament, 175mm Change Colour Filament (Green to Yellow) in the centre.I was fortunate to receive some of this ABS from BilbyCNC.com.au to have a play with and I'm so excited by the possibilities I've been hesitant to use it for anything as yet. So c'mon Thingiversees.. let see what we can do with this new medium!!!
