[3dem] LaB6 question

[Marcus FISLAGE]

Hi,

I do not have a problem with my LaB6 filaments that I buy up to one year in advance.
That way I am always sure to have one on stock in case of an unexpected failure of the current filament.
I leave it in the vacuum seal, however.

Cheers
Marcus

Hello,



Yes, our engineers strongly advise against it. They prefer that we order the filament just before installing it.

Hi,



Does anyone worry about keeping a spare LaB6 filament for several years before using it?
