The Sunlu TPU Silk Filament is a high-quality, flexible filament ideal for a range of 3D printing applications. Known for its vibrant, silky finish, this filament combines the elasticity of TPU with an eye-catching shine, making it perfect for both functional and decorative prints.
Key Features: Material: Thermoplastic Polyurethane (TPU) with added polyester for enhanced flexibility and strength. Diameter: 1.75mm Weight: 1kg Color Options: Black, Cream White, Light Blue, Dark Blue, Burgundy
Print Recommendations: Near-end Extrusion: Optimal within 50mm/s with retraction or 60mm/s without retraction. Distal Extrusion: Ideal within 20mm/s without pumping back, or 30mm/s without pumping back. Softness Focus: No filling and wall thickness between 0.8mm to 1.2mm. Elasticity and Hardness: Increase filling to 5-15% and maintain a wall thickness of at least 1.2mm. This filament is environmentally friendly and ideal for various applications such as flexible brackets, high-grip robot wheels, and decorative items with a soft, shiny finish. For best results, avoid printing hollow models or those with excessive overhangs. This filament is a versatile choice for makers looking to add a touch of elegance and flexibility to their 3D-printed projects.
Safety Precautions:
Always print in a well-ventilated area.
Avoid breathing the fumes while printing.
Do not touch the nozzle, heated bed, or printed object right after printing — let it cool down first before handling.
Keep the printer and filament away from children and pets.
Unplug the printer when not in use.
Store the filament in a cool, dry place to avoid moisture.
Wear gloves and a mask when sanding, cutting, or handling printed parts.
Keep away from open flames — most filaments are flammable.
TPU / TPE (Flexible Filaments)
Print with basic ventilation.
Let flexible prints cool down before removing from the bed to avoid burns or deformation.
