DUAL EXTRUDERS IN THE area OF ONE STEPPER motor

The new hotness in 3D printers is – as well as has been for a while – double extrusion. With two extruders as well as the requisite filament supply, it’s possible to print objects in two colors or two different materials. There’s a issue with this setup, though: each extruder needs a separate motor, greatly decreasing the print area ought to you want to print in two or much more colors. [Carl] as well as [Brian] believe they have the service to this with their double extruder that is powered by one stepper motor.

As you can see from the picture above, the concept is fairly simple. two strands of filament are fed past one gear connected to a stepper motor. Each strand is moved into the hot end with two idler gears as well as side of the extruder feeds into the hot end is identified by the rotation of the motor. It’s truly one of those, “why didn’t I believe of that” ideas.

[Carl] as well as [Brian] are likewise providing a quad extruder, a dual-sized extruder able to pump four different filaments onto a printer bed. With this, we expect some people to try out CMYK (or CMYW) prints, really turning any type of 3D printer into a device that prints full color parts.
