TPE (Thermoplastic Elastomer) is a highly durable polymer that combines both thermoplastic and elastomeric properties. What makes this material so attractive for manufacturers is its ability to return to its original shape without damage after being moderately stretched. That is only possible due to its rubber-like characteristics, which also make 3D printing in TPE the ideal choice for applications that need to be resistant to impact and vibration.

Besides, TPEs exhibit great chemical stability, and resistance to abrasion, fatigue and tear. These unique material properties and benefits are one of the reasons why 3D printing in TPE is becoming more popular and even replacing traditional rubbers. The main difference to TPUs is that TPEs are softer. TPUs are a type of TPE but with different hardness levels.

Another advantage is that TPEs are usually heat resistant allowing it to be sterilized. Parts that are 3D printed with this rubber-like material are suitable for many industrial and medical applications as well as functional prototypes.
