SUNLU Silk TPU Flexible 3D Printer Filament - Light Blue, 1.75mm, 1kg

SUNLU Silk TPU combines the flexibility of TPU with a distinctive silky, satin-gloss surface finish. Unlike regular matte TPU, prints come off the bed with a subtle sheen that makes flexible parts look as good as they feel. This 1kg spool of light blue Silk TPU is ideal for decorative yet functional flexible parts - watch straps, phone cases, fashion accessories, toys and cosplay pieces.

Every spool is produced with laser-monitored diameter control and held to a tight 1.75 ± 0.02 mm tolerance, keeping extrusion smooth and consistent through long prints. SUNLU's fully automated winding lays the filament 100% neatly on the spool - no knots, no tangles, no mid-print failures.

Key Features

  • Silky satin finish: a smooth, lightly glossy surface unique among flexible filaments - no post-processing needed.
  • Genuinely flexible: over 950% elongation at break with Shore 98A firmness - soft-touch parts that hold their shape.
  • Impact and abrasion resistant: stands up to daily wear, oils and weather.
  • Precise 1.75 ± 0.02 mm diameter: laser-monitored for smooth extrusion and clean layers.
  • 100% neatly wound: automated spooling means no knots or tangles.
  • Wide compatibility: works with most 1.75mm FDM printers, direct-drive recommended.

In the box

  • 1 x Silk TPU filament spool, Light Blue, 1.75mm, 1kg net weight

Good to know

  • The silk sheen shows best at slightly higher nozzle temperatures and moderate speeds. Keep retraction low to avoid stringing.
  • TPU absorbs moisture faster than PLA. For the best surface quality, dry the spool at 55-65°C for 4 hours before printing, and store it sealed with desiccant.
  • A PEI sheet or glue stick helps both adhesion and easy release of flexible parts.
