BASF Ultracur3D EL 150 Transparent by Forward AM is a high-quality photopolymer 3D printing resin from the Ultracur3D series. This transparent resin is designed for applications requiring flexibility and toughness, making it ideal for technical components, seals, or functional prototypes. With a Shore hardness of approximately 80A, it offers a rubber-like consistency while maintaining good shape stability. The resin's high detail resolution allows for fine structures and smooth surfaces, suitable for complex models. Ultracur3D EL 150 is optimized for SLA and DLP printers with a wavelength of 355 to 405 nm and can be processed at layer thicknesses of 25 to 100 µm. Typical curing time is 2 to 4 seconds per layer, depending on printer power. Post-processing involves cleaning in isopropanol and UV curing (e.g., 405 nm) for 10 to 20 minutes to enhance mechanical properties. Safety precautions include wearing gloves and working in well-ventilated areas, as the resin can irritate skin and eyes. Ultracur3D EL 150 is an excellent choice for users needing flexible, transparent parts with high precision.
