PPrint P-filament 721 1.75mm 0.6kg The polypropylene (PP) filament 'P-filament 721' offers low warpage and shrinkage combined with an extremely high layer adhesion and can be printed with almost all common 3D printers. P-filament 721' and the prints made with it are very break resistant, have very good mechanical properties, high chemical and temperature stability, as well as low frictional resistance. Due to its low density, it is excellently suited for lightweight construction. Applications ranging from technical components to individualised decorative and art articles to toys can be realised. The food-safe nature of the PP starting material used opens up additional possibilities. Pre-treatment of PP-filament 'P-filament 721': 'P-filament 721' does not need to be dried before 3D printing and can be used without pre-treatment. Recommended print parameters: 'P-surface 141' as print substrate mandatory Extruder temperature: 200 - 220 °C Print bed surface temperature: 20 °C (50 - 70 °C during the first layer, 100 - 110 °C for non-destructive removal after completion) Build temperature: not necessary Storage instructions: To ensure consistent print performance, 'P-filament' should be used and consumed as soon as possible after opening. It is best to store opened material at a temperature of 15 - 25°C and in a plastic bag to prevent contamination with dust.
