PETG-HT is an enhanced version of PETG, specifically designed to withstand high temperatures and exhibit excellent mechanical properties.
Material Details
PETG-HT (High Temperature) is a modified version of PETG filament that is specifically engineered to have an increased glass transition temperature (Tg). The glass transition temperature is the temperature at which the material transitions from a rigid to a soft and pliable state. PETG-HT is designed to withstand higher heat environments compared to standard PETG filament.
Due to its higher Tg, PETG-HT is suitable for applications that involve exposure to elevated temperatures, such as functional prototypes, automotive components, mechanical parts, and industrial tooling. It offers improved dimensional stability, reduced warping, and enhanced resistance to heat deformation compared to regular PETG filament.
PETG-HT retains many of the desirable properties of PETG, including good layer adhesion, low shrinkage, and resistance to chemicals, making it a reliable choice for a wide range of 3D printing applications.
