t-glase is taulman 3D’s version of PETT which is meant to be a direct 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 an ultimate tensile strength when printed of 4500PSI and 7.8%+ elongation to break which outperforms ABS. However, it has a lower glass transition temperature of 76C compared to the 90C Tg of typical FDM ABS filaments. 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 taulman’s t-glase is the optical properties of the specialty PETT material. When printed in clear, t-glase is partially transparent, clouded only by the interfaces between layers.

If optical clarity is the goal in your design, we recommend printing at layer heights measuring approximately 80-90% of your nozzle diameter, slicing at a larger nozzle size, running your printer slow, and applying XTC-3D solution to the part after it finishes printing.

Since it has such good layer adhesion, brim removal can be difficult. Also due to it’s layer adhesion and properties, parent support material can be very difficult and complex models can be a nuisance trying to print.

Our preferred extrusion temperature for t-glase is 235C with our build plate heated to 45C. t-glase prints well at slower speeds of 50mm/s off a 0.6mm E3D nozzle. Layer settling times are particularly high on t-glase (and other PET based materials). We recommend using active print cooling as you would with PLA.

t-glase material comes in multiple color variations direct from taulman 3D.
