7. FLEXI

Flexible materials are made from thermoplastic elastomers and soft rubbery materials that often include additional additives. TPE, TPU, and sometimes TPS are the most commonly used types. These filaments are predominantly soft and elastic, allowing them to withstand high levels of stress.

Flexibles enable a high level of detail and almost perfect surface finish. This technology facilitates the creation of very precise models or functional products where it's necessary to simulate the flexible properties of rubber or silicone. These materials can withstand temperatures up to 90°C.
