nGen Flex was developed with Eastman chemical company. Based on their work with co-polyesters, nGen Flex makes a very compatible material with other Amphora grade materials (nGen, XT, HT). This means you can expect to mix both materials with good adhesion properties to truly form a dual-extruded model. With just the right amount of flex, nGen Flex is best described as a semi-flexible material.
Flexible and Tough
Printed in single perimeters and with very little or no infill, objects will feel quite flexible. When printed with multiple perimeters and more infill, objects will be very firm and tough. The material is rated at a shore hardness of 95A.
nGen Flex is temperature resistant to about 130C. That means 3D printed objects can be steam sterilized at 121C, which is a great asset for medical and laboratory environments.
