Polypropylene (PP) is a very versatile material, semi-transparent, light, recyclable and with good organoleptic properties.
The pieces printed with the PP Polypropylene filament offer flexibility, excellent mechanical and chemical resistance, as well as an excellent resistance to bending that make it ideal for a large number of industrial applications.
The pieces made with PP filament stand out for their resistance to abrasion and for their ability to absorb shocks (resistance to impact), resistance to fatigue (Hence, it is used in hinges) and also has a relative rigidity and flexibility. On the other hand, one of the main drawbacks is its sensitivity to UV rays. While there is already a material in 3D printing to alleviate this weak point of most plastics that is the ASA filament.
