What is the Polypropylene, or PP, HP material?
PP (Polypropylene) or HP 3D High Reusability PP is developed by BASF. This 3D printing material is an industrial-grade polypropylene. PP provides a high reusability ratio, producing functional parts batch after batch. The goal of this material is to be more sustainable and produce at higher volumes.
Polypropylene has always been highly used in industrial manufacturing due to its good mechanical properties. Using this material for additive manufacturing is now opening a wide range of new possibilities, and accelerating the shift of many companies to digital manufacturing. PP can be used by designers, engineers, and businesses to produce advanced 3D printed prototypes, but also final parts. This PP 3D printing material is manufactured using Multi Jet Fusion (or MJF) technology on the HP MJF 5200 printer.
What are the possible applications for this material?
PP 3D printed using Multi Jet Fusion technology can be used by the automotive, industrial, medical, or consumer goods sector. This industrial-grade material is perfect to manufacture automotive parts found on the interior and exterior parts for the automotive / transportation industries.
The formula of this PP powder developed by HP and BASF offers great chemical resistance, high elongation at break, but also durability and low moisture absorption. PP 3D printing material is perfect for industrial uses, from pipes to machinery, but also to create reservoirs for due to its chemical resistance properties.
Using additive manufacturing to create reservoirs or packaging will allow to produce parts with intricate shapes, perfectly adapted to the whole design of your devices.
With its excellent chemical resistance, low moisture absorption, and long-term durability, PP is ideal for piping, fluid systems, and containers. For example, automakers will be able to use the same PP for prototyping and production of final parts found in vehicles’ interior, exterior, and under-the-hood.
What are some companies working with HP PP?
HP is jointly developing entirely new PP applications with partners, parts providers, and customers including Extol, specializing in plastics engineering and innovation with industry leading plastic assembly technology, custom automation, and engineering services; GKN Powder Metallurgy/Forecast 3D, a provider of advanced industrial 3D printing, short-run manufacturing, and high-volume production; Henkel, a leader of high-impact adhesives and engineering solutions; Oechsler, a leading additive manufacturing parts provider; and Prototal, one of Europe’s most experienced parts manufacturers.
