Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from. We provide a 100% satisfaction guarantee on all filament we sell. If you have any problems, just send back the unused portion of the spool for a full refund. Check out our filament collection...
