Ultimaker R&D - We want your ideas!

[eldrick 65]

I've been contemplating dual-extruders, but not for multi-color prints with poor quality, or for supports, but as an Alternate extruder:

- I'd like to be able to switch nozzle sizes for speed vs. precision, perhaps .35mm on one, and a .5 or even .7mm nozzle on the other,

- Reserve one nozzle for ABS and the other for PLA, to avoid the inevitable clogging that seems to go with switching materials on the UM2.

If intermixed extrusion was not required, perhaps the cost could be lower if only a single extruder/motor were used, with a method to easily switch Bowden tubes to change from one material or nozzle to the other.

I´ve only used Um2 for about 3 weeks now.

I think cura is a great program, easy to use/learn.

Some suggestions:

- implement auto off in cura when program is finish as an option

- Auto save position of part when reloading model

- Change the noisy fan

- 2 extruders, one for supportmaterial to get better support=flatter and smoother underside? just dreaming on last one but maby it is possible..
