Colour Printing



First attempt at two colour printing, not the most astonishing object but you can see the potential.
The print has been done on a BfB V3 machine fitted with twin extruders. The two single colour objects were printed together from one file, the two colour object by swapping heads through the build, changes triggered by G_Code.
You can see the potential for running support material along with the main print, swapping seamlessly back and fourth between the two.

The wall is single filament thickness so alignment has to be reasonably good between the heads. The object is far from perfect as its only the third print of a new machine fitted out with the twin head.
More to follow on this.

Comments:
first it all, where you get that cool blue and red plastic ?
 
Nice.
A Software calibration value could compensate for differences in the physical head position.
 
about time someone's gotten back to multi-head printing! well done.
 
The ABS came from BfB, they have several colours available:
Red, Blue, Green, Yellow, White, Black.

Murray, Yes I use a calibration var for the head position, this was the first test so its not dialed in yet, needs about another 0.5mm adjustment to nail it.
 
Smooth arcs too; are those gcode arcs, or just many segments? Nice work!
 
Hi Wade,
The G_Code has been generated by Skienforge so the arcs are made up of many segments
