nGen is a great all-round 3D printing filament for everyday use. Another co-operation with Eastman Chemical Company, nGen is made with Eastman Amphora AM3300 3D Polymer. It has good flow properties through the printer nozzle – even at lower temperatures than some other polymers require. These properties make nGen more workable at a wider breadth of temperatures, producing reliable results and resulting in less waste. nGen exhibits advanced overhang ability, excellent looks, and large printing temperature range — empowering users to create durable and useful items. Material: colorFabb nGen Diameter Tolerance: ± 0.05 mm Density:1.20 g/cm3 Glass Transition Temperature: 85C Advised 3D printing temperature: 220-240C Advised 3D print speed: 40 – 70 mm/s Advised Heated bed: 75-85C Build platform: nGen gives best results on a heated build platform, 75C to about 85C is usually needed for proper adhesion to a glass plate. Printing on a cold bed is possible but you’ll need some adhesion tools to minimize warping. Magigoo can do the trick.
