SKU: Pegasus PP-HGS25 Ultralight

Pegasus PP-HGS25 Ultralight is most likely the lightest PP filament in the world!
Pegasus PP-HGS25 is a PP filament that is enhanced with hollow glass nanotechnology, which makes this 3D printer filament 20% lighter than virgin PP filaments.
The modification with 25% hollow glass microspheres made from soda-lime borosilicate glass not only make Pegasus PP-HGS25 an extremely lightweight filament,
but also significantly stiffer than normal PP filament. The inherent properties of the added hollow glass microspheres provide a number of unique performance advantages,
such as weight reduction, dimensional stability, thermal insulation and a lower dielectric constant.
This makes Pegasus PP-HGS25 an extremely versatile 3D printer filament for various applications such as automotive, drones, floating applications,
and applications that require lightweight, wear resistant and durable parts.

General printing guidelines *

Nozzle size: ≥ 0.4mm Layer height: ≥ 0.1mm Flow rate: ± 104%
Print temp: ± 215 – 245° C Print speed: Low Retraction: Yes ± 5mm
Heat bed: ± 0 – 100° C * Fan speed: 50-100% Experience level: Intermediate

*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends and printer offsets that it is extremely difficult to give an overall one-size-fits-all setting.

*) Large Pegasus PP Ultralight prints can be printed on an unheated 2mm or 3mm PP plate, which can be attached to the print bed. Smaller prints can be printed on standard PP packaging tape.
