Filament Evaluation Object

I use this to evaluate the baseline condition of filament if it has been unused for a while, or if it is new.

Here are a few of the things you can learn from examining the results:

1. Detect filament diameter variability, hollow filament, and bubble voids.

A rough surface, with streaks and pits will indicate these type of conditions.

2. High Moisture Content

The straightness of the wall edges and surface, rising from the base, and the absence of splitting are desireable, and found if the filament is dry.

3. Ideal bed temperature

Warping in the first 10 mm might indicate the bed is too hot.  Peeling away at the base, then too cold.

4. Ideal Hot End Temperature.

Even though the part is very thin, it should resist a 30° bend without splitting. If you need something to compare too, split the lip of a Dixe cup, and tear.  It shoulf feel at least that strong.
