t-glase (PETT) t-glase is a high quality Polyethylene terephthalate polymer. It is modified to provide a 5% higher amount of reflectivity making it more equivalent to a glass polymer. t-glase is also processed using the same techniques taulman3D developed for nylon. Full processing allows for a polymer that easily prints at 232C - 242C. A temperature easily obtained by all FFM 3D Printers. t-glase is also a high strength polymer meant for industrial applications. The major advantage of t-glase to all other polymers, is layer to layer bonding. Because the polymer bonds so well, there is no need to smash a large number of thin layers together to accommodate a good bond. Industry uses layer settings that are 70% to 100% of the nozzle dia with excellent results. t-glase has a very low shrinkage factor and is best printed on acrylic or glass print beds heated from 50C to 80C depending on part size. As with nylon 645, 680 and 910, the clarity of t-glase supports industrial non-destructive evaluations. In addition, t-glase is a directly printable polymer for glass clear jewelry. Users should watch the blogs for new 3D Printing jewelry designers to start advertising. And due to the additional reflectivity, t-glase is considered the only high transmission light-pipe polymer. Due to it's chemical make-up, light transitions easily along the path of a printed thread. This allows the designer to draw and print a light-pipe with any path required. t-glase can not be colored with standard dyes. Instead, special dyes are injected at the output master die during manufacturing.
Temperature - Optimum temperature is about 235c to 240C, but will print down to 212C and up to about 248C.
FDA approved – t-glase is specifically made of FDA approved polymers for direct food contact/containers. This includes cups and other liquid storage parts as well as utensils. We are working with the chemical company to provide you with FDA related documentation so you may sell your printed parts that meet FDA requirements. These documents will be posted below when available.
Environmental - While t-glase is not biodegradable like PLA, it is a material that’s considered 100% reclaimable. Thus the new “struders” that convert failed prints back to usable line work perfectly with t-glase. If you have a “struder”, you can actually mix in 12% of the total weight in discarded clear water bottles. Please keep in mind, that the polymer used in most water bottles, has a slightly higher melt temp and that adding them to the mix, may increase print temp a few degrees. Clarity – t-glase is considered colorless per industrial classifications. t-glase is considered "water clear" as it will not degrade to a color in multiple layters of applied thickness. t-glase’s clarity supports industry’s requirements for non-destructive evaluation of 3D Printed parts.
Shrinkage - Very low shrinkage makes printing large flat surfaces a breeze. And it easily prints to acrylic, glass, Kapton and other platforms.
Bridging - Those of us that have printed with acrylics and poly carbonates are always envious of their bridging capabilities due to glass temperature. And the new t-glase is very impressive at bridging.
Fumes - Unlike some lines, there are no odors or fumes when 3D Printing with t-glase.
