Veeology dual-color filament is a dual-color filament extruded with two different colors and substrate mix, which has great strength and toughness, and is environmentally friendly, smokeless and odorless, with low material shrinkage, and can print double-sided models of different colors with dazzling effects. The wire diameter 1.75mm PLA filament is manufactured with advanced and precise diameter measurement. The dimensional accuracy is +/- 0.03mm. In addition, fully mechanical winding and strict manual inspection ensure neat and less tangled threads, thus avoiding possible breaks and thread breakage, and you can enjoy smooth printing during the whole process. PLA printed filament is completely dried for 24 hours before packaging and vacuum sealed in a transparent bag with desiccant to protect the filament from moisture. You can get a perfect packaging and reliable filament with the recommended PLA filament extrusion/nozzle temperature of 180-210°C. No heating raft is required and the printer requirements are low.
