Basic guidelines for printing with TPU and Flex filaments include setting the heatbed temperature in the range from about 20°C to about 80°C. The nozzle temperature should be set in the range from 210°C to 240°C. 3D printers capable of printing from TPU and Flex materials can be successfully used to print accessories for mobile devices (e.g. cases), toys, and everyday items. In addition, the TPU and Flex thermoplastic material is perfect for printing various types of tools.
