14.2 Convergence Dual Extruder
The extruder although has similar size of a single extrusion extruder but essentially it
is two extruders made into one. The Convergence dual uses a direct extrusion
design and has 2 gearbox-stepper motors build into it. It has two cooling fans, one
for cooling the hotend and the other is a toolpath coupled fan for cooling printed
models.
Convergence Dual Extruder
Convergence Dual is a patented technology by Tiertime.
The Convergence hotend has two channels “converge” at one nozzle opening, the
two channels can extrude different materials alternately. Since the two extrusions
share a single nozzle, there is no need for nozzle alignment calibration. The two
material will always be aligned perfectly.
