Polylactic acid filament for 3D printing reinforced with silica

Abstract

A polylactic acid filament for 3D printing comprising polylactic acid reinforced with silica as a functional additive exhibiting improved mechanical and thermal properties. The filament possesses a high tensile strength and a stiffed property, providing enhanced durability and structural integrity. Additionally, the filament demonstrates a high degradation temperature, ensuring stability during hightemperature processing. These combined features render the PLA filament particularly advantageous for applications requiring robust mechanical performance and reliable thermal resistance in 3D printing and related manufacturing processes.
