Need something that’s, like, really transparent? Don’t like the yellow tint natural PLA gives you, but still want something that’s easy to print? Then Taulman’s T-glase is the filament for you!
T-glase is arguably one of the most iconic materials from US manufacturer Taulman, promising optically clear prints with strong, glass-like refraction, but still good printability. As a copolyester, it clocks in at a decidedly premium price of 71€ per kg. I printed it with a 20% part cooling fan setting, using a heated bed at 65°C covered in glue stick to make part removal easier, and the hotend set to 240°C.
The overhangs test scored only 3 out of 5 points, for some visible curling, but fine details and stringing were decent, with the bridges test not exhibiting sagged lines, but instead individual strands that snapped on one end, which are easy to clean up. The 3DBenchy shows off the mesmerizing optical properties, which can be improved even further by using a wider nozzle and a larger layer height.
Because t-glase is more than twice as flexible as PLA, and even quite soft compared to other copolyesters, one of the bend tests did not show a meaningful failure mode, and as such i’m inclined to use the scoring system intended for flexible filaments, which only factors in the two pull tests with the octagonal specimen. Either way, T-glase scores an ok, low mid-range score. Heat resistance is decent, with more strength retained than PLA, but less than ABS. In summary, t-glase is a great choice for its optical clarity and can even take a bit load if don’t mind the extra flexibility.
