Review on Fused Materials 3D Printer Cleaning Filament by Simo Ramsey

Basically: not possible. Doesn't stick to the bed, even with gluing or welding. The thread is stiff and brittle, it breaks into short pieces. They then get stuck in the extruder and are not pulled back when changing filaments between layers. These bits then mess up your print and cannot be easily removed. Heed the warning that leaving the printhead in the printer without fully cleaning it could damage it. This is an awful product. If you like having a reason to get angry and swear, then this product is for you!
