POLYPROPYLENE is our easy to print general purpose low-density Polypropylene. PP has been developed for optical clarity while maintaining mechanical performance and a superb layer adhesion. Polypropylenes high stretch ability, decent flexibility and chemical/fatigue resistance makes it suitable for a variety of household articles and containers. PP can also be used for engineering articles such as living-hinges and snap-fit fastener materials. Lastly PP can be used to print dishwasher & microwave safe objects. PP is a cost-effective all round filament suitable for a broad variety of needs.

Packaging:
PP is available in nearly any type of packaging and labelling. Ask our team to help you customizing your product.
Additional info:
PP does not adhere to any print sticker well enough to counteract warp on large objects, therefore we recommend a Polypropylene sheet (inexpensive). If you have a heated bed the recommended temperature is ≤85°C. Adherence improves when the first layer temperature is higher.
Printing with a raft improves bottom layer removability and evens out unconformities in the PP sheet.
PP can be used on most common desktop FDM or FFF technology 3D printers.
Storage:
Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
