Description

technical field [0001] The invention relates to a composite material additive manufacturing device with a rotary curved surface structure, and belongs to the technical field of composite material rapid prototyping equipment. Background technique [0002] Traditional 3D printers based on the principle of fused deposition technology (FDM) usually use a single thermoplastic resin material to print and form parts. Due to the constraints of the mechanical properties of the material, the strength is often low, and it is not suitable for applications that require a large bearing capacity. Fiber-reinforced composite materials have the outstanding advantages of high specific strength and specific modulus. The combination of 3D printing technology and fiber-reinforced composite material molding process can largely overcome the defects of low mechanical properties of single-component materials. In recent years, composite material 3D printing technology has achieved rapid development. T...
