MakerBot PLA filament is the best and most consistent filament for the MakerBot printer. MakerBot PLA filament is a bioplastic derived from corn. Every filament color is comprehensively quality tested at both 100-micron and 200-micron layer resolutions on the MakerBot Replicator 2 to verify that the filament will perform every feature that MakerBot MakerWare and MakerBot desktop software offer. If you're better to 3D printing, MakerBot PLA filament is a good material to start with because it's easy to use and performs well on most prints.
