Filament
http://www.plastic2print.com/eu/175mm-fep-filament-0-75kg.html FEP, FEP (Fluorinated Ethylene Propylene) is a high grade material with a long list of truly some remarkable properties. Here are some highlights: outstanding chemical resistance; high thermal stability (service temperature rating up to more than 200 °C); extremely low flammability. As with most things in life, it comes at a price: the high melting temperature of 260 °C means that you will need a all-metal hotend to handle this. And because it is just release from our factory, we do not have in-depth guidelines on how to get the best results. But if you need the above material specifications, there is no real alternative.
 * Nozzle temperature	280-320°C
 * Heated bed temperature	+/- 140°C
