REFILL is a non-spool cartridge compatible with the reusable spool MASTERSPOOL standard, which anyone can print by themselves using the RichRap's free and all-available project. This solution is more ecological and slightly cheaper in comparison to the filaments offered on disposable spools. Fiberlogy is one of the first few companies in the world that has decided to add the solution to its range.
The application is the same as in the case of filament spools. The only difference is that the refill does not have a spool. This makes it environmentally friendly and there is an extra win. Because the shipment is lighter it is also cheaper.
