Question 1

Where do FilamentFacts temperatures come from?

Accepted Answer

They are copied from the Open Filament Database dump 2026.10.13. Dataset imported 13 October 2026. SpoolmanDB filled a missing nozzle temperature on 19 products and a missing bed temperature on 19, and only when the brand, material, and product name matched. That date is the dataset generation date, not a lab measurement.

Question 2

Why is a temperature left blank?

Accepted Answer

If a number is not in our current sources, the cell is an em dash. FilamentFacts does not estimate a nozzle or bed range from the material family.

Question 3

Do crawlers see a different deal price than visitors?

Accepted Answer

The page HTML includes the email field and the checked price. A script shows one of them. Without that script, the email field stays visible.

Question 4

How does the printer filter decide whether a filament fits?

Accepted Answer

It compares the listed nozzle and bed temperatures with that printer's maximums. Partial means the printer cannot reach the full recommended range. Outside limits means the listed minimum is already above the printer maximum. Enclosure and a hardened nozzle are checked when those records exist. A missing nozzle or bed temperature is not called a fit.
