HP 3D polypropylene (PP) is a material designed for 3D printing using HP’s Multi Jet Fusion technology, based on thermoplastic polypropylene. The low density and minimal moisture absorption of PP, in addition to its chemical resistance, are just some of its outstanding qualities.
3D printing with PP is ideal because the high isotropic mechanical properties of polypropylene mean that printed parts have the same strength throughout their entire volume. As a result of this quality, functional prototypes made of polypropylene, as well as PP fixtures and components can all be successfully produced.
Where the material is used
The non-flammable 3D printing PP material has a high chemical resistance, so it does not change its properties when interacting with various chemicals or materials.
Automobile industry
The material is used to create functional polypropylene prototypes of automobile parts, such as fairings, instrument panels, ventilation grilles and internal components. The PP filament’s properties allow the final products to withstand the required loads and chemical influences.
Electronics
3D printing with PP can be used to create enclosures and fasteners for electronic devices, such as panels, connectors, and holders. The chemical resistance of PP for electronics and device enclosures ensures that components will be protected from external factors.
Industrial manufacturing
PP is useful for creating fixtures, tools, and parts for industrial manufacturing. Functional PP prototypes have sufficient strength and durability to withstand the demands of the manufacturing environment.
Packaging
3D printing using HP 3D polypropylene is used to produce boxes, containers, lids, and pallets. PP has sufficient strength and resistance to external influences to make it suitable for use in the transportation and storage of goods.
Post-processing
Black coloring for printed parts
After printing, parts have a gray, rough-textured surface. To enhance their appearance and durability, we offer black coloring. This is a fast and cost-effective way to achieve a high-quality, uniform finish.

High physical characteristics
Products made of PP have a gray coloured surface. The layers of this material are thoroughly sintered, making the final products strong and highly resistant to abrasion.

Because PP products have a non-porous structure, they do not need to be impregnated with epoxy resins. The material can be used to print pipelines and hermetically sealed containers.
The properties of PP end-use products and fixtures will be preserved after long periods of contact with chemicals. Parts will be durable even when interacting with greases, solvent, gasoline and alkaline media.
HP 3D polypropylene does not contain carcinogenic PAHs, heavy metals, bisphenol A, or phthalates. It can safely interact with intact human skin. The material’s biocompatibility is confirmed by USP Class I—VI certification, while its low hazardous substance content is confirmed by RoHS and REACH, “Composition Safety Statement” and PAHs certification.
PP is suitable for parts that do not come into contact with open flames, as evidenced by UL 94 and UL 746A documents.
PP for 3D printing is environmentally friendly and does not require special storage conditions. Excess powder can be reused after the product has been printed.
