The one concern of the previous design http://www.thingiverse.com/thing:2195351 was that multiple filaments couldn't be driven at the different velocities. Using the CVTs for the each filament feeder allows to tune-up the relative…
The Joined PiNion Extruder, proposal for the multi/fullcolor printing. Many concepts are based on the Bowden extruders. One drawback of the Bowden is a slag hysteresis when extrude/retract. This makes the accurate color mixing difficult.…
I wonder if something like this might work. Possible to either machine in two parts or even one block? The PTFE tubes enters the into nozzle (like in MK10) but the nozzle acts also the heating block. Obviously the tricky part is to drill…
The previous version of the concept got the massive rate of the interested. After sleeping over the night I thought the there is still many expensive components. Here are two new concepts! The drive has two options 1) normal gear pull but…
