Smartbuy 1.75mm Black ABS 3D Printer Filament - 1kg Spool (2.2 lbs) - High Precision +/- 0.05mm - Perfect for 3D Printing, DIY Projects & Prototyping

I have printed a dozen items with this filament now and it has worked well the entire time. I use a ROBO 3D and have experienced no jams, no nozzle plugs and no other problems. This represents over 50 hours of total printing time. Seems like a very good filament for the price.
