What do you look for in 3D filament?

Name one thing that you value the most in 3D filament. And why?

[Steve]

We strongly recommend using the correct filament for the UP printers.
The filament must be round, and of a consistent diameter.
We have found lots of other products miss feed due to being inconsistent.

Also the melt temperature is critical as this cannot be adjusted within the up software.

Thank you Steve.
We agree. Perfect roundness & consistency are the key for filament quality.
We'll keep that in mind.
