Quality Control :
1, All of Our 3D Printer Filament are 100% virgin material, never use recycled material or regrind material,
and all had achieved the latest REACH certificate.
2, Before the mass production, our engineer always do the test to make sure that sure that each batch of
new raw materials must be printed by 3D printer.
3, The Laser diameter runs automatically to control the diameter of the filament and keeps it in a 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, We to keep the filaments dry, each roll of filament is packed in a vacuumed poly bag with a desiccant
inside of it.
