SUNLU PP Filament
SUNLU PP filament combines low weight with exceptional toughness and chemical resistance. It is up to 27% lighter than PLA and allows for the production of stable yet flexible parts with reduced material consumption. Thanks to its food safety, outstanding resistance to acids and solvents, and excellent fatigue resistance, it is ideal for functional, everyday, and industrial applications that require safety, durability, and reliable performance.
The printed product is lightweight (PLA has a density of approx. 1.23 g/cm³, while PP has a density of approx. 0.9 g/cm³), making it about 27% lighter. SUNLU PP filament creates lightweight yet stable parts, reducing material consumption while maintaining high performance – ideal for functional prints and everyday projects.
SUNLU PP filament is food-safe and suitable for printing containers, kitchen utensils, storage boxes, and other applications where reliability and safety are essential.
SUNLU PP filament has been developed with superior chemical corrosion resistance. Polypropylene filament withstands the effects of acids, alkalis, and solvents, ensuring stability and long-lasting performance in demanding environments.
With its exceptional toughness, elasticity, and fracture resistance, the SUNLU PP 3D printing filament offers impact resistance and flexibility, making it perfect for durable, resilient parts.
[Printing Tips]
To ensure optimal first-layer adhesion, use a print surface specifically designed for PP materials. Apply PP adhesive, set the part cooling fan to only 10%, and print in an enclosed chamber to minimize warping. To improve adhesion between the print and the platform, it is recommended to add skirt structures around the print. To avoid warping caused by the crystallization of the PP material, you should avoid dense and rectangular infill patterns.

Are our filaments (such as PLA, PLA+, etc.) food-safe?
Are our filaments (such as PLA, PLA+, etc.) food-safe?
PLA is a food-safe material, but toner is added to the filament during the production process, and it can also become contaminated by the print nozzle during the printing process. Therefore, we recommend that you do not use PLA for printing tableware.
