450 grams, 1 LB of Taulman T-Glase It should be noted, that t-glase is a high strength PET polymer and prints with standard setting used for PLA but with a print temp of about 235C. All of the cooling profiles and techniques used for PLA apply to tglase. Large industrial users like AOSmith and others as well as hundreds of machine shops use t-glase for it's non delaminating feature when printing large parts. However to gain an increase in transparently of the final part for aesthetics, one needs to increase layer size and in doing so would need to slow the printer down based on the increased material flow. 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. Clarity – t-glase is considered colourless per industrial classifications. t-glase is considered "water clear" as it will not degrade to a colour in multiple layers 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.
