Help / Troubleshooting

Why is my filament brittle or snapping in the spool?

Either it absorbed moisture, or it was stored hot and humid. Both have fixes.

Two causes. One: it has been sitting open in humid air for weeks — dry it. Two: it is old or stored hot — PLA hydrolyzes when stored above 30 °C with humidity. Forgely spools are vacuum-sealed with desiccant; brittle out of the bag means it is a manufacturing or shipping issue and we will replace it.
