SUNLU PP Polypropylene 1.75mm Filament 0.8kg Spool

Lightweight, Flexible, and Chemically Resistant – Perfect for Functional Prototypes

The SUNLU PP (Polypropylene) filament offers a unique balance of flexibility, toughness, and chemical resistance, making it ideal for practical engineering applications and functional prototypes. PP is known for its low density, giving printed parts excellent impact resistance and fatigue strength while remaining lightweight.

Key Features:

• Extremely lightweight – perfect for weight-sensitive designs
• Outstanding chemical resistance to most acids, alkalis, and solvents
• High impact and fatigue resistance for durable parts
• Low moisture absorption – resists warping and deformation
• Excellent layer adhesion for strong, semi-flexible prints
• Good transparency – ideal for visual or translucent models

Specifications:

• Filament Diameter: 1.75 mm ± 0.02 mm
• Spool Weight: 0.8 kg net
• Print Temperature: 220 – 250 °C
• Bed Temperature: 80 – 100 °C (use polypropylene build plate or PP tape for best adhesion)
• Print Speed: 30 – 60 mm/s
• Enclosure: Recommended for optimal layer bonding
• Packaging: Vacuum-sealed with desiccant to prevent moisture absorption

Ideal For:

• Functional prototypes and mechanical components
• Containers, caps, and fluid-handling parts
• Automotive and household items
• Hinges, clips, and flexible mechanisms
• Lightweight enclosures and low-friction parts

Note: Polypropylene has a low surface energy, which makes it challenging to adhere to standard build surfaces. For best results, print on a PP build plate, PP tape, or with an adhesion-promoting surface such as a glue stick formulated for PP.
