Diameter of filament

[punpunm 2]

Is it possible to use 1.75mm filament?

I want to try the wood filament, but I bought the wrong one. Should I try to open and print it?

Does any one have try to use 1.75mm on Ultimaker 2?

Return it.

It's possible but not worth the trouble. Ideally you have to replace the clear bowden tube, replace the nozzle and the peek part leading to the nozzle and modify the feeder so that it can clamp onto 1.75mm (this last might not be necessary).

In practice you can sometimes get away with it but if you print at reasonable speeds the pressure is too high and melted PLA shoots back up the nozzle into the upper chamber of the print head and cools there and causes horrible blockages.

So you will have to print at 10mm/sec. So a 1 hour print will now take 10 hours.

Just return it. You can get the new filment faster than your second print finishes.

Oh - ultimaker 2? It's even worse as I dont' think the feeder can close all the way and modifying the UM2 is not as fun as modifying the UM Original.
