Strength: 4,516 PSI • Elongation: 7.8% • Tg: 76°C

T-glase is a version of PETT which was developed to directly substitute for any material currently being printed in ABS. It has improved layer to layer bonding properties which allow it to achieve a higher tensile strength than typical ABS prints. T-glase has a tensile strength when printed of 7080PSI and 7.8%+ elongation to break which outperforms ABS. However, it has a lower glass transition temperature of 76C compared to the 105C Tg of ABS. This is perfectly suitable for outdoor applications, but may be a concern if placed in operation next to machinery generating significant heat.

Another interesting benefit to T-glase is the optical properties of the specialty PETT material. When printed in clear, T-glase is semi-transparent, clouded only by the interfaces between layers.


• High tensile strength

• Good substitute to ABS

• Most transparent material available

• Available in multiple colors


• Lower glass transition temperature than ABS

• Prints slower than standard materials

• Doesn’t work well with support or complex models
