Ultraviolet Resistance Ultraviolet resistance measures a 3D printed material's ability to withstand UV radiation without degradation, discoloration, or brittleness. It is essential for outdoor applications, signage, and products exposed to sunlight. UV-resistant materials include ASA, PETG, and specialized UV-stabilized resins. Proper additive formulations, including UV absorbers or stabilizers, enhance weatherability and color retention. Post-processing techniques like UV-resistant coatings or protective films further improve durability. UV resistance expands applications in automotive, construction, and consumer products requiring long-term stability and appearance. |
