HDglass HDglass is a high performance filament based on an unique PETG blend resulting in an amorphous, high strength, high gloss and ultra-transparent 3D printer filament. HD stands for Heavy Duty, as HDglass is developed to have an optimal thermal stability and by that perfect 3D printing flowing behaviour, resulting in a very easy to print 3D printer filament with a remarkable high gloss, transparency and excellent properties with respect to strength, toughness and temperature resistance. Unique features Extremely transparent and high gloss 90% optical light transmittance with only 1% of haze Easy to print Nearly warp-free and perfect inter-layer adhesion Good first layer adhesion to a heated glass print bed and many other surfaces Compatible for printing at high speed Odourless processing/printing High strength and toughness compared to similar materials Watertight printing Engineered to be compliant to FDA food and drink contact articles General printing guidelines *
