The combination of durability, sandability and ease of painting make CosPLA version B the perfect choice for your next cosplay 3D printing project. Compatibility In Mind - Polymaker CosPLA Version B is compatible with a wide range of3D printers and works well with many common printing surfaces and a 30 - 60°C heatedbed. Jam-Free™ technology - Polymaker CosPLA Version B is manufactured with PolymakersJam-Free™ technology which improves the heat stability of the filament with softeningtemperatures over 140°C and leads to excellent printing quality with zero risk of nozzle jams caused by heat creep [1].Uncompromised Quality - Manufactured with Polymakers industry leading compounding and extrusion systems, Polymaker CosPLA Version B filament is made with the highest quality ingredients and formulated to deliver a reliable 3D printing filament for cosplay and prop applications.[1] Heat creep is the the process of heat spreading irregularly throughout the hot end, one common example is with all metal hot end designs. Once heat creeps towards the cold end, the PLA filament softens prematurely in the cold end and expands resulting in a jam. Polymakers Jam-Free™ technology increases the heat resistance of the filament itself (not the printed part) to 140°C which prevents the filament from prematurely softening in the cold end and can still melt
