…Having a background in large scale optics, we wanted to make sure that if there was a development for FFF printing of transparent parts, that t-glase would play a part as the base polymer. During the development we made a decision to enhance the clarity of t-glase with a very slight trade off in the Tg in the final chemical formulation. This has initially allowed some sites and designers to design jewelry components using a thicker layer during the printing process to give the part more of a glass like appearance.
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 esthetics, one needs to increase layer size and in doing so would need to slow the printer down based on the increased material flow.
…A company that specializes in 2 part artistic and industrial epoxies, “Smooth-On” released a product called “XTC-3D” for coating 3D Printed parts a few weeks ago. We purchased the product and again performed some quick tests to determine if the product would fill the need to convert a cup from a cylinder of threads, to a clear glass. The photos below show the results. We are now suggesting the product to our users that need additional clarity in their printed parts….
