3D-basics Value Resin in Translucent Orange is a premium engineering resin offering an excellent balance of hardness, detail resolution, and cost-effectiveness. Its semi-transparent orange color makes it ideal for functional prototypes, technical models, and applications requiring visual inspection of internal structures. The resin features high hardness and toughness, making printed parts resistant to mechanical stress. It has low viscosity, ensuring rapid recoating and smooth surfaces, allowing even intricate details to be reproduced precisely. This resin is compatible with common DLP and LCD/MSLA 3D printers operating at 405 nm wavelength, providing reliable curing with layer times of approximately 4 to 8 seconds at 25 µm layer thickness. Post-processing requires cleaning models in isopropyl alcohol followed by UV curing (405 nm) for 15 to 30 minutes to achieve final mechanical strength. Suitable applications include engineering, product design, and the creation of miniatures. Due to its opacity and rigidity, it is less suited for dental or jewelry applications requiring extreme transparency or flexibility. Safety precautions are essential; always wear nitrile gloves and safety glasses to prevent skin irritation. Store in a cool, dark place to prevent premature polymerization.
