Silk PLA PETG ABS TPU Silk 3D printing filament
Quality controlled
We controlled filament quality and tolerance as below five steps.
Step 1: 58um Stainless steel filters to ensure no impurities
Step 2: Online observation and warning.
Step 3: Control diameter. we have patents to controlled tolerance under +-0.03mm.
Step 4: Filament Quality inspection by QC.
Step 5: Printing test for each order and colors.
Patent control is important: Controlled line diameter +/-0.03mm,filament should be testing on the producing. if tolerance is over +/-0.03mm, filament can pass hole 1.78mm and warning and production automatic stopped.
So all filament controlled +/-0.03mm 100% quality.
