Hello,

I put my homemade 3D printer in the garage when I moved 2 years ago, the filaments I had were maybe 2 years old and worked well.

I bulk bought them on aliexpress or maybe alibaba.

Now, the printer needs a refreshing, a bit of all kind of electrical & mechanical stuff and also figuring out how to run it from my new computer, and I wonder if I should buy some new filament so that I won’t have to care about any old filament problems or what do you think? Is my filament dead or maybe ok?

Thanks!

Edit: thank you all!

I’ll go with buy a new high quality one to get everything up and running, and then I’ll check out the quality of the old spools. Who are stored open, but in a airtight box with a kilo of, now grey, alibaba deciccant pellets.

    Definitely go first with a new spool of well-known filament. Though I have had very good experiences with old filament, I recently had an issue with a spool of PET that would not adhere to the bed, and I tried drying it out for several hours. Mind you, this same spool had worked wonderfully in the past but I don’t know what happened to it. Imagine that you tried to use a spool like that to calibrate your first layer!
