Innovative Applications of Liquid Silicone Rubber in 3D Printing Technology
With the continuous advancement of 3D printing technology, an increasing number of materials are being incorporated into its applications. Among them, Liquid Silicone Rubber (LSR), a high-performance elastomer, is emerging as a new favorite in the 3D printing industry. This article explores the applications of Liquid Silicone Rubber in 3D printing technology and the innovative advantages it offers.
Properties and Advantages of Liquid Silicone Rubber
Liquid Silicone Rubber is an organic silicone elastomer composed of alternating silicon and oxygen atoms in the main chain, with organic functional groups attached to the side chains or both ends. Its unique molecular chain structure gives it excellent resistance to high and low temperatures, aging, biocompatibility, and high transparency. These properties have made LSR widely used in aerospace, automotive manufacturing, electronics, and biomedical fields.
