RESIONE 3D Printer Resin, Rubber/TPU Flexible Resin, Tear-Resistant and High-Elongation Photocurable Resin 405nm DLP LCD MSLA for 3D Printing UV Resin (1000, Black) 【High Elongation, Tear Resistant】Elongation at break: 255%, Tear strength: 47.2KN/m. The printed models after secondary curing did not break even after repeated bending and stretching. 【Soft like rubber】Shore hardness: 60-75A. The printed models become very soft at temperatures above 20°C, but become harder at lower temperatures. At 5°C, it becomes very hard and impact-resistant. 【As a reinforcing agent】By mixing with tough resins such as F69/F39/F39T 3D printer resin and K/M58/M68/G217, printed objects can be made more durable and long-lasting, and will not become brittle over time. 【Many uses】You can beautifully create prototypes of models such as shoes and wearable devices. It is also ideal for figures (such as enamel dolls) and resin parts (such as tires) that require flexibility.
