SUNLU continues to expand its 3D printing filament portfolio with PETG 2.0 and Silk 2.0, two materials developed to address common challenges faced by makers while improving the overall printing experience.

PETG 2.0: Designed for More Consistent Printing

PETG is one of the most used filament on the market and in the same time sensitive to moisture. When exposed to humidity, water molecules can penetrate the material and interact with its molecular structure, causing problems such as stringing, bubbles, and poor layer adhesion. Our PETG 2.0 has been developed to remove the moisture concern from the head of the users, helping them to achieve more consistent printing results straight out of the box.

Our testing demonstrates how moisture content can influence print quality over time. In controlled testing, PETG 2.0 maintained normal tower-tip printing even after being left in the open for 15 days, while other filament brand would experience stringing,bubbles and failures. The testing also highlights the importance of proper filament storage and drying to maintain consistent performance.

The testing further demonstrates the benefits of drying PETG 2.0 before printing. After drying at 65°C for 12 hours, the filament was tested again after being exposed to different conditions, allowing us to evaluate how moisture levels affect printing performance.

Silk 2.0: A More Refined Silk Finish with Improved Performance

Alongside PETG 2.0, We are also introducing Silk 2.0, developed to improve upon the visual qualities traditionally associated with silk PLA while addressing some of the performance limitations users may experience with silk filaments.

Silk 2.0 delivers a high-gloss, eye-catching surface finish, making it particularly suited to decorative models, display pieces and other projects where appearance is important. SUNLU's testing includes comparisons with existing silk filaments and competing products using brightness measurements to evaluate the visual finish.

However, Silk 2.0 is designed to go beyond appearance alone. We highlights its improved notch impact performance, providing an advancement in mechanical performance compared with conventional silk filament. This development addresses a common concern with silk PLA, which can be more prone to brittleness and breakage.

With PETG 2.0 focused on more consistent moisture-sensitive printing and Silk 2.0 combining a striking silk finish with improved toughness, We continue to develop materials designed to meet both the functional and creative needs of today's 3D printing community.
