PPprint GmbH, the German specialist for 3D printing polypropylene (PP) for professional, technical and medical technology applications has announced its partnership with Rever Industries, one of India’s leading filament manufacturers, to offer their product portfolio to the Indian 3D printing market.
Nashik-based Rever Industries is not only one of the authorised PPprint resellers, but will also offer polypropylene 3D printing services to customers across India.
Polypropylene (PP): The material of choice
Polypropylene (PP) is one of the most important polymers worldwide, combining outstanding recyclability with superior mechanical, chemical, and biocompatible characteristics. PP is therefore already used in a wide range of production technologies and also offers enormous potential in additive manufacturing, especially in extrusion based (FDM/FFF) 3D printing. PPprint pursues the mission to establish the material PP with its unique product portfolio globally for 3D printing for industrial applications.
For a successful extrusion-based 3D printing of polypropylene, three critical components are necessary
- The printed material itself should have low warpage and high interlayer bonding strength.
- The 3D printing build surface has to allow reliable 3D printing of PP parts and a non-destructive and residual-free removal of the finished part without any additional chemicals.
- A support material is required to print complex structures with overhangs and openings which can be easily removed from the finished part.
PPprint GmbH – the specialist for 3D printing polypropylene solved these three challenges. Their current product portfolio includes the PP filament product line ‘P-filament 721’ which is available in the diameters of 1.75mm and 2.85mm. In addition to natural, white, and black, ‘P-filament 721’ is commercially available in 8 different colours. The filaments offer low warpage and very high interlayer bonding strength. Furthermore, 3D printed parts of ‘P-filament 721 natural’ are certificated for biological safety according to DIN EN ISO 10993-5.
Additionally, PPprint developed a special 3D printing build surface ‘P-surface 141’, which enables reliable and reproducible printing of PP. The 3D printed parts can be easily and defect-free removed from the ‘P-surface 141’ at elevated temperatures.
With ‘P-support 279’, PPprint GmbH launched the world’s first break-away support material specially developed for polypropylene in 2021, which enables the 3D printing of highly complex and sophisticated structures like bridges, overhangs, and. The support material ‘P-support 279’ enables 3D printing of even more intricate designs and can be conveniently and cleanly removed manually from the printed part at elevated temperatures after the 3D printing process.
