Polypropylene Filament - Polypropylene (PP) filament is a new semi crystalline thermoplastic used in Fused Filament Fabrication (FFF). PP filament is a homopolymer and has wonderful properties that make it a useful plastic. Polypropylene has a high level of flexibility yet has great toughness meaning it is elastic without being too soft. Polypropylene is resistant to many chemicals and has a high resistance to electricity making it useful in electronic components. The versatile polypropylene is a plastic used in our everyday lives in the form of packaging, labeling, lab equipment, stationery, and more. One of the most beneficial uses of polypropylene is to create food safe containers because polypropylene is odorless and nontoxic. Although polypropylene is recognized as FDA safe for food, the inherent process of creating printed objects from current 3D printing standards are most likely not FDA safe. Most extruders have brass heads that may leach 3D printers such as those based off of the RepRap model will leave printed objects with a porous structure, a perfect growth site for bacteria. Some users have dabbled in sealing printed objects in Polyurethane, but that still wouldn’t solve all of the issues with producing food safe products in current 3D printing standards. Another issue would be the dangers from extruder nozzles. If the nozzle is made of brass, then lead might leach into the print. Extrusion temperature for polypropylene filament is 230-260°C the build plate should be heated between 60°C to 110°CIf any queries you can contact us on 9969555777
