Ubis 13 stainless steel nozzles...

Postby DonaldJ » 2016-May-Sun-10-May

Got a pleasant surprise with the Ubis 13 nozzle six-pack I received last week. Although the .75mm and 1.0mm nozzles are brass, the rest of them appear to be stainless steel (non-magnetic, too heavy and wrong color for aluminum).

Another stealth upgrade from Printrbot?

I believe they are nickel plated. Ni provides a hard coating with a higher lubricity than the brass.

SS is an upgrade if you're going to use abrasive filaments like ColorFabb XT-CF20, but it has a lower thermal conductivity than brass, so print quality can be compromised.

I'm not sure...I hit it with a small triangular diamond file and I see no hint of yellow color indicating brass.

In any case, this type of nozzle is performing very well.

Interesting!

The reason I said Ni plated was because Brook mentioned that to me at last year's Bay Area Maker Faire.
