3D Printer filament is generally expensive, but one Chinese company is not only offering affordable filament, but also filament with some innovative new qualities. Torwell Technologies is selling 1kg spools of a new color changing filament, both in PLA or ABS. The filament is priced at around $20 per kg spool, if 8 or more spools are purchased. They also offer other filaments, for as cheap as just $14 per kg. We have samples coming and will be testing it out shortly. We will be sure to post the results here. More details on the company and the filament can be found here: http://3dprint.com/10324/torwell-cheap-3d-filament/
