This category of 3d printing filament feels just like rubber. TPE is a copolymer which means it has both elastic and plastic properties. TPE filaments are used in prototypes which need parts that require bending or flexibility.
The layer to layer adhesion is impressive in elastomer TPE, so there are minimal chances that your print will separate after cooling.
It is heavily used in commercial applications such as automotive parts, medical supplies, shoe soles, weather sealing for doors and windows, electrical insulation, smartphone covers, and wristbands.
It has good weather, ozone, and UV resistance.
This extremely flexible 3D printing filament will allow you to create prints which have properties of a soft rubber, making it even more elastic than PLA. Since it is quite flexible, speed needs to be slow during the printing process because these filaments can bind to the extruder. The printing temperature needs to be between 225-235C.
TPE is not soluble, but it is ideal for making toys, novelty items, belts, caps, bumpers, etc.
