FilamentSwitch

I think a filament switch could be a good way to print in multiple materials. Repetier should tell a snipper when to cut the fill when it is needed to end one material, then introduce the next. any ideas on clever mechanisms that could feed filament through the rocker arm?

a tube with two inputs, (or however many materials you want) and one output. one extruder, a snipper on the ‘V’ output, and two stepper motors.

one stepper motor, a switch that moves a gear to the roller that feeds the appropriate fillament.

the switch is probably a solenoid,

servo

This is the first of parts for a filament switch to cut and feed new filament into one extruder on a printer.

the main stepper motor could stay, that grips the fill after the cutter. two small motors, one on each branch need only turn on to start the feed to the main motor.

no idea how to wire the motors so that repetier says when to switch filaments.

two stepper motors, one extruder, ; maybe the program can be controlled to retract the filament instead of cutting it…

why not?

You should check out this Kickstarter project. : https://www.kickstarter.com/projects/mosaic3d/the-palette-3d-printing-evolved/description

They have something cool developed already

Cheers

I just swap out colors as the print is going, Or dye the white filament with sharpie marker

Robo 3D stopped by the TCT booth at CES 2015 to talk about its two new 3D printers and working with Spectrom.

the link is an automatic way of full color

In your extruder allows pull out the filament, you counl user the pause print in the Cura plugins ant Z height to make a puse, maintaining the extruder temp.

Something like this? but double. http://www.thingiverse.com/thing:610866

thanks, right, that’s not right

E3D made something sort of like that. I think it was a dual motor/dual filament input sort of a Y that fed into the nozzle. The filaments retracts and extrudes from one or the other, as needed. It would be a little bit messier that two nozzles, but it looked promising

Thanks for reties, I’m thinking the color palette is good. Curious how it times what color to advanced, when the different pigment is on the same layer. But I’ll research. Thanks.
