SUNLU TPU Silk B filament pre 3D tlačiareň 1,75 mm 1 kg čierna

SUNLU TPU Silk B is a thermoplastic polyurethane filament that combines flexibility with a striking silk finish. This black 1.75 mm filament is engineered for FDM 3D printers, offering a Shore hardness of 95A and excellent elongation at break of 500%, making it ideal for functional parts that need to withstand bending and compression.

Highlights

• Premium TPU with a glossy silk surface for high-quality prints
• 1.75 mm diameter with a tight tolerance of ±0.02 mm for consistent extrusion
• 1 kg spool, vacuum sealed with desiccant to keep moisture out
• Print temperature range: 200–230 °C
• Heated bed optional (50–80 °C) for better adhesion
• Bubble-free material for smooth, reliable printing

In daily use

This filament is perfect for creating flexible parts like gaskets, phone cases, straps, and wearables. The silk texture gives your prints a premium look, while the material's elasticity ensures durability and resistance to impacts. We recommend a print speed between 20 and 50 mm/s, and a direct drive extruder for best results. For optimal layer adhesion, keep the printing environment free of drafts and use a heated bed if possible.
