Prusa Research Releases PPCF and PETG Magnetite 40% Filaments
PPCF offers high chemical and heat resistance, while PETG Magnetite 40%’s “paramagnetic” properties hold a ton of potential for both professional and hobbyist use.
Prusa Research has launched two new filaments: PP Carbon Fiber (PPCF) and PETG Magnetite 40%.
PPCF is, of course, a Polypropylene-carbon fiber blend: a durable and lightweight material – so much so that Prusa mentions drone and aircraft-related applications – with high heat and chemical resistance. Automotive parts, as well as containers designed to hold oils or chemicals, are other examples of potential use cases here.
The material comes at an opportune time for Prusa, which recently announced its carbon fiber filaments to be safe after extensive testing, while some commentators have compared carbon fiber filaments to asbestos. Additionally, PPCF can conveniently be used with Prusa’s new PP Sheet, which is specifically designed for Polypropylene materials and should help users avoid adhesion issues. PPCF is priced at $69.99 USD for a 650 gram spool.
Prusa’s PETG Magnetite 40% filament boasts “paramagnetic” properties, meaning it can stick to magnets, but is not magnetic itself, making it a good choice for switches – or anything else that needs to open or close, then stay that way – as well as hobbyist applications like toys or anything “that can be attached to a magnet”.
A 1 kg spool of PETG Magnetite 40% costs $46.99 and requires a hardened nozzle to print.
Prusa’s blog post introducing the two materials contains a great deal more information, including a useful chart that documents PPCF’s resistances to various substances and solvents, and a deeper dive into the science behind PETG Magnetite 40%’s (para)magnetic properties.
