Product Description: HDglass is an amorphous, high strength and ultra-transparent modified PETG compounded 3D printer filament range. HD stands for Heavy Duty, as HDglass has excellent properties when it comes to strength, toughness and temperature resistance for same like materials. Next to being heavy duty, HDglass has a very impressive transparency as it is an amorphous filament, which lets 90% of the visible light pass through its fibre and has less than 1% haze. With HDglass you are now able to get the closest approximate to glass-like results for 3D printed objects. Printing with HDglass filament is very easy and comfortable as it has a great thermal stability, and superb first- and interlayer adhesion and does not produce any odours during 3D printing. HDglass is a perfectly save material as it does not contain any hazardous substances, is Bisphenol A free, RoHS certified, REACH compliant, and is even FDA food and drink contact approved. Because of its unique transparency and glossiness, the HDglass compound allows itself to be coloured in the most beautiful transparent and bright opaque colours. This same superb transparency and glossiness makes HDglass a perfect base material for adding thermal-, or UV light sensitive colour effects. HDglass is available in a variety of vivid colours and prints best at a printing temperature range within 215C and 250C. Printing with HDglass is remarkable easy, as it is a very easy to process material and an excellent first layer adhesion can be obtained by printing at various undergrounds without needing a heated print bed. Dependent of the size of the printed object, HDglass can be printed at a high printing speed. As a matter of fact increasing the print speed makes your HDglass 3D printed object even more transparent.
