Printing Settings- Nozzle: 215-230C, Bed: 50-60C, Speed: 60-600 mm/s(depends on layers). Ultra Fast Printing Speed- R3D High-Speed filament is engineered to help pros push the boundaries of their ingenuity and creativity. R3D High-Speed PLA filament is the first PLA filament to support 600mm/s* in 3D printing speed. Masterpiece Precision- Rapid heating at the hot end and swift cooling post-extrusion contribute to achieving a smoother and more detailed print model. Ultra Low Density- The R3D High-Speed PLA is crafted from innovative PLA pellets, and our unique formula empowers it to yield a remarkable 11% more printed material than standard PLA. Its low density additionally minimizes the shrinkage rate to the utmost extent. Design For AMS- The Clear GPPS spool and AMS are a perfect pairing for the ultimate 3D printing station. Featuring a 200mm diameter and a robust GPPS spool, our R3D High-Speed filament keeps rolling smoothly without any residue or breakage. Jam-F
