Feature Introduction:
OBC K7 is a polyolefin block copolymer-modified material. It introduces polyolefin properties to 3D printed products, including low water absorbency, flexibility, durability, and chemical resistance. Thus, resistant to several common solvents, it is not damaged by humidity changes and can be used after long-term storage. It is designed for an ultra-low density, with 20-40% longer than other materials at the same weight. In addition, it is economical and can print lightweight and durable products.
