To maximize the shine and quality of prints with PLA Silk+, it is recommended to reduce the printing speed of the outer wall. Thanks to the improved layer adhesion of Bambu PLA Silk+, this speed reduction does not compromise the strength or bonding of the layers, ensuring an elegant and professional finish.

It is essential to dry the filament before use to ensure a uniform finish and avoid problems during printing. Recommended methods include: in a drying oven at 55°C for 8 hours or on the bed of an X1 printer at 65°C–75°C for 12 hours. After use, it is advisable to store the filament in a dry environment to maintain its quality and consistency. For more detailed instructions, you can consult the filament drying guide available in the WIKI.

For the best quality on the top surface of the parts, it is suggested to use a concentric pattern on the top layers. This setting optimizes the appearance of the outer layers, providing a smoother and more uniform finish, ideal for decorative models and parts requiring high aesthetics.
