I may be late to the party with any discussion on this. Is there any commercial upgrade kit available, to turn a UM2+ into a dual extrusion machine? I haven't found anything but it seems like the print head is designed to take another heater block assembly. Thanks in advance.

Thanks guys. Xile6, where did you buy your hotend from? Yours looks different from mine with the spring setup inside.

The old style olsson block. They use to use springs. Then switch to a solid cylinder. The spring allow you to adjust the height of each nozzle.

I order them from aliexpress also done a 1.75 filament conversion. But they do sell it in 3mm also so it will be a direct swap.

Ive seen that and does look nice. Just more involved that I want to get lol.

 

Ok, that is fine. But if you want to modify your Ultimaker 2 to dual extrusion, and only printing a new print head housing and docking station (almost all other parts are included in the available extrusion train upgrade if I'm not mistaken)  is too much work I am afraid that you will have to significantly compromise in reliability. Making something reliably dual extrusion takes far more into account than just installing a second nozzle.

lol..

I do alot ,built over a hand full of printers modified firmwares etc... Been around since pretty much the start of them pretty much. MY printer also has some other upgrades. 1.75 filament, titan extruders, all aluminum fan shroud, octoprint.

 

My dual upgrade simply needed the heat block, nozzle, heater and temp sensor. Vs buying a whole new hot end and everything else.

Was simply my choice. It works just good. There is some oozing which can be dial in setting. But it does what it needs to. Never had a reliability problem. And most of the time i just use 1 nozzle. So i keep different filament in each one, so i dont have to unload and change all the time. Normally pla in one and petg in the other.

Also have a palette 2 coming which will do 4 color/materials single nozzle no oozing.

 

So no need for the mark2 upgrade to me. It doesnt have anything over my current setup for me.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
