The R3D HT-PLA Gray Filament is a high-temperature-resistant PLA filament with a diameter of 1.75 mm and a net weight of 1 kg. It features an increased Vicat softening temperature of 155.2 °C, making it significantly more heat-resistant than standard PLA. This material is particularly suitable for components exposed to higher temperatures. With a tensile strength of 40 MPa and a flexural modulus of 4106 MPa, the filament offers excellent mechanical properties for functional printed parts. The elongation at break is 11.8 %, indicating a balanced ratio between stiffness and flexibility. The filament is compatible with nozzle sizes from 0.2 to 0.8 mm and supports use in automatic material change systems (AMS). The impact strength is 4.2 kJ/m², while the interlayer adhesion is 2.7 kJ/m². For optimal print quality, the manufacturer recommends storing the filament in a cool, dry environment at 15 to 25 °C and protected from UV light. All spools are sealed and packaged with silica gel to minimize moisture absorption.
