"&lt;p&gt;Taulman T-Glase PET Co-Polymer&lt;/p&gt;\r\n&lt;p&gt;Ttaulman3D has released another high strength material.  One for those users that print mostly with PLA or lower temperature 3D Printers.  This new material is called \u201Ct-glase\u201D  (tee glass) short for tough glass.   \r\n&lt;/p&gt;\r\n&lt;h3&gt;The main features of t-glase&lt;/h3&gt;\r\n&lt;p&gt;&lt;b&gt;Strength&lt;/b&gt; - Specifications on the strength of t-glase will be posted as \r\nsoon as the data is returned from the test labs. We have started using a local \r\ntest lab along with the lab's at a few universities to accumulate data. The \r\nprocess involves printing several &amp;quot;test bars&amp;quot; These are bars printed at 5&amp;quot; x .5&amp;quot; \r\nx .25&amp;quot;. The setup for printing these is 1 perimeter and 100% solid layers.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Temperature&lt;/b&gt; - Optimum temperature is about 212c to 224C, but will print \r\ndown to 207C and up to about 235C. &lt;br&gt;\r\nNOTE: A feature of t-glase was to select a polymer that easily sticks to heated \r\nacrylic and glass print tables for the smoothest bottom surface possible. While \r\nt-glase meets this requirement, it results in a low glass transition \r\ntemperature. The effects of a low TG is that parts printed in t-glase, should \r\nnot be exposed to high temperature use or applications. The measured TG of \r\nt-glase is 78C.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;FDA approved&lt;/b&gt; \u2013 t-glase is specifically made of FDA approved polymers for \r\ndirect food contact/containers. This includes cups and other liquid storage \r\nparts as well as utensils. We are working with the chemical company to provide \r\nyou with FDA related documentation so you may sell your printed parts that meet \r\nFDA requirements. These documents will be posted below when available.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Environmental&lt;/b&gt; - While t-glase is not biodegradable like PLA, it is a \r\nmaterial that\u2019s considered 100% reclaimable. Thus the new \u201Cstruders\u201D that \r\nconvert failed prints back to usable line work perfectly with t-glase. If you \r\nhave a \u201Cstruder\u201D, you can actually mix in 12% of the total weight in discarded \r\nclear water bottles. Please keep in mind, that the polymer used in most water \r\nbottles, has a slightly higher melt temp and that adding them to the mix, may \r\nincrease print temp a few degrees.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Clarity &lt;/b&gt;\u2013 t-glase is considered colorless per industrial classifications. \r\nt-glase is considered &amp;quot;water clear&amp;quot; as it will not degrade to a color in \r\nmultiple layters of applied thickness. t-glase\u2019s clarity supports industry\u2019s \r\nrequirements for non-destructive evaluation of 3D Printed parts.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Shrinkage &lt;/b&gt;- Very low shrinkage makes printing large flat surfaces a \r\nbreeze. And it easily prints to acrylic, glass, Kapton and other platforms.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Bridging&lt;/b&gt; - Those of us that have printed with acrylics and poly \r\ncarbonates are always envious of their bridging capabilities due to glass \r\ntemperature. And the new t-glase is very impressive at bridging.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Fumes&lt;/b&gt; - Unlike some lines, there are no odors or fumes when 3D Printing \r\nwith t-glase.&lt;/p&gt;\r\n&lt;p&gt;t-glase is very strong, yet different from our nylons as it\u2019s stiff, like PLA \r\nand ABS. And based on our first industrial trials, meets all the requirements \r\nfor the three industrial customers that had an applicable need. To these \r\ncustomers, the clarity was a significant advantage for their quality control \r\ndepartments. &lt;/p&gt;\r\n&lt;p&gt;First, t-glase is made from the highest optical quality PETT material and is \r\ncurrently only available from two chemical plants. Unlike other polymers, some \r\nPETT, including t-glase are not considered \u201Ctransparent\u201D. Instead, it belongs to \r\na group of polymers that are considered \u201Ccolorless\u201D and or \u201Ccolorless with a \r\npercentage of reflectivity\u201D. t-glase is also considered \u201Cwater-clear\u201D and \r\n\u201Coptically correct\u201D. The term \u201Coptically correct\u201D simply means that if you have \r\na lens based die and injection mold precision reflective PETT into the die, the \r\nresulting lens will be relatively close to the same lens made from glass. While \r\nthere is no formal definition of \u201Cwater-clear\u201D, in optical engineering, it\u2019s a \r\nreference to how high quality plate glass seems to disappear when placed in \r\nwater. When a clean piece of high quality glass is placed in water, the water \r\nnegates the flat surfaces as a reflective surface, thus making the major surface \r\ninvisible. However, the edges of the plate glass will still redirect or reflect \r\nlight in a different direction, thus making them viewable even in water. This \r\nwater-clear property is why some of products we buy are displayed in \r\n\u201CBlister-Pack\u201D packaging. The material is based on PETT with processing that \r\nbring out it\u2019s reflective properties and enhances the visual presentation of the \r\nproduct. Over and above the problems associated with removing said product from \r\nthe packaging! &lt;/p&gt;\r\n&lt;p&gt;&lt;a target=\"_blank\" href=\"http://www.taulman3d.com/t-glase-features.html\"&gt;Read \r\nmore about Taulman T-Glass on Taulman Website here&lt;/a&gt;&lt;/p&gt;\r\n&lt;p&gt;&amp;nbsp;&lt;/p&gt;\r\n"^^<http://www.w3.org/2001/XMLSchema#string>
