1. To enhance the gloss of your print’s appearance, it’s recommended to slow down the Outer wall printing speed. No need to worry about the reduced adhesion found in generic PLA Silk—Bambu PLA Silk+’s improved layer bonding fully supports this adjustment.

2. Although PLA Silk+ is thoroughly dried and vacuum-sealed prior to shipping, variations in transport conditions may affect its moisture level. We strongly recommend drying it right after opening and storing it in a sealed container with desiccant or AMS. Repeat drying and moisture-proofing before each long-term storage period.

3. Dry before use to ensure the best print quality and consistent finish. Drying conditions: In a blast drying oven: 55°C for 8 hours; On an X1 printer’s heatbed: 65°C to 75°C for 12 hours. Store in a dry environment after use. For more details, please refer to: Filament drying instructions on WIKI.

4. Concentric top surface pattern can optimize the print quality of top shells
