nGen Flex gives best results on a heated build platform, 80 °C to about 100 °C. A BuildTak plate is recommanded for better adhesion. When removing a part from the buildTak plate we advice to cool down completely and reheat to 80 °C. To increase plate adhesion use the brim feature, removal after printing is very easy, the brim peals right off after making an initial cut.

The suggested 3D print speed is around 30-50 mm/s. To reach higher speed / output of material, you might need to increase temperature. The material handles higher temperatures very well. 

Printed in single perimeters and without infill or very little, objects will feel quite flexible. Printed with multiple perimeters and more infill, objects will be very firm and tough. It’s also important to adjust the minimum layer time when you want to print without cooling for best layer adhesion.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider our tips as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
