Notes on printing with Ninjaflex

Always use at least a minimum of 30% infill, the higher the better. Print at a slow speed: 20-30mm/sec (1200-1800mm/min for simplify3d). Extrude at a temperature between: 210-225°C. Not really needed, but you can have the platform bed temperature set to: 20-50°C. To reduce stringiness, set retraction for 1.75mm filament, to 2-3mm. Go with the lower amount if using an Ed3. Another option is to turn on the… View More
