A LED visible light curable 3D printing material is a 3D printing material that can be cured at high speed and with high accuracy even with LED light by using particular radical reactions. A variety of lineups are available to suit different applications. The RH-series has low warpage and high heat resistance, while the RHL-series has high toughness. In addition, the RS-series is flexible and can be bent up to 180 degrees. The RCA-series is characterized by being heat erasable and the RVF-series by being capable of ultra-fast curing. Many 3D printers and resin materials are manufactured overseas and are costly, and it takes time to receive products from the moment an order is placed. These products are manufactured in Japan and can thus be acquired more cheaply and also enables quicker response as compared to those manufactured overseas. A variety of resins are available for various 3D printers (SLA, DLP, LCD, and IJ types) and they can also be customized for customers. In addition, the materials technology of the NAGASE Group exhibits high toughness, high heat resistance, and high definition, and is used for wax casting and model manufacturing.
