Food-Grade Polypropylene Filament for 3D Printers
(3Ders.org) It’s now possible to 3D print plates, cups and other food containers as well as children’s toys using food-grade polypropylene (PP) filament. Available at German RepRap, the new PP filament is made of semi-crystalline thermoplastics and is being produced according to US FDA regulations and the relevant EU standards.
Similar to plastic food storage containers, PP-based models have a soapy surface and high level of flexibility. For the best results, printer temperature should be set to at 210°C. The PP filament can be used with all printers that have a 3mm hot-end. It is available in black and a 2.1kg spool costs 99.95 EUR. Th 750g spool goes for 54.95 EUR.
