Working with two nozzle is not as simple as Single Nozzle. While working we experienced some facts that are not published well. People Just know dual nozzle use to get print dual color or soluble support. However without knowing the fact about its operation, demanding dual nozzle is not wise choice. Here is some of the practical constrain about dual nozzle which we believe you may get aware.
1 .Oozing other Nozzle – While one nozzle is printing , other nozzle oozing due to high temperature. When 2nd nozzle start printing, its plastic ooze stuck with object wall, which affect the object appearance.
4. Shifting of both the color – Generally distance between nozzle need to add in the firmware. If the distance is not accurate or disturbed, both the color do not print in proper alignment, and it seems shifting of both color. This cause the object weakened at the boundary of the colors.
JAK Machinery have now developed the single nozzle dual color extruder, which takes two color as input but extruder from the single nozzle. All the above problem solved
