A Designer Grey PLA Authentic Robox SmartReel 3D printer cartridge (MPN: RBX-PLA-FS391) . SmartReel Cartridges are sealed in reusable ziplock bags with a silica sachet in order to maintain the low moisture content required for the best 3D printing. Robox filament has a filament diameter of 1.75mm and each SmartReel contains approximately 600grams of PLA, equivalent to 240m of filament.
Whats so special about the Robox Filament Cartridge?
Each reel houses and EPROM (erasable programmable read-only memory), which is re-writable memory board. This allows information about the contents of the robox filament spool to be included on the eprom which can then be updated as the contents of the spool change, for instance how much filament is left on the SmartReel or what the printing temperature should be.
The filament is compatible with any 3D printer that uses 1.75mm PLA but the eprom is only compatible with the eeprom reader attached to the Robox desktop 3D printer.
