Winkle PP is a polypropylene filament made in Spain. This semi-crystalline thermoplastic combines low density, flexibility and mechanical strength. It is hydrophobic, resists chemicals and fatigue, and allows elongation of up to 200 % before break.
It comes in 1.75 mm diameter on a 700 g spool, in Natural or Black, for hinges, clips, containers, laboratory parts and components subject to repeated torsion.
Printing conditions
Winkle recommends a 0.4 mm nozzle, an extrusion temperature of 220 to 250 °C and a speed of 30 mm/s, with the first layer at 25 mm/s. Printing takes place in a closed enclosure, on a heated bed, with an adhesive to improve polypropylene grip. The low electrical conductivity of the material suits insulating parts.
