1. All of our 3D printer filaments are 100% virgin material, never use recycled material or regrind material, and all had achieved the latest REACH certificate.
2. Before mass production, our engineer always does the test to make sure that each batch of new raw materials must be printed by a 3D printer.
3. The Laser diameter runs automatically to control the diameter of the filaments and keeps it in the right range of 1.75/3.0mm, and our engineer will adjust it immediately when it alarms to indicate of wrong size, and this unqualified filament will be cut off and never use it.
4. To keep the filaments dry, each roll of filament is packed in a vacuumed polybag with a desiccant inside of it.
