Designed for the Dreamer, Inventor Series, and Adventurer 3 3D printers, the gold 1.75mm Ultra-Strong Pearl PLA Filament from FlashForge is a high-gloss PLA and polyester blend filament designed to produce high-quality models with a silky pearl finish. Due to the added polyester, it is less brittle than PLA. Pearl also maintains several of PLA's printing qualities such as low odor, high detail, and low warpage. This 1.75mm filament operates at print speeds ranging from 60 to 90mm/s and printing temperatures of 374 to 428°F.
