Description

Technical Field

[0001] The utility model provides a single-nozzle high-performance composite material 3D printing device, belonging to the technical field of 3D printing devices. Background Art

[0002] The FDM (Fused Deposition Modeling) process generally uses thermoplastic materials such as PLA and ABS, which are fed in filament form. The material is heated and melted in the nozzle, which moves along the part's cross-sectional contour and filling trajectory while extruding the molten material. The material quickly solidifies and solidifies with the surrounding material, and this cycle continues until a complete part is processed.

[0003] Conventional plastic filaments such as PLA have low melting points and poor physical properties. They can be melt-printed using a simple frame-open FDM device, and the printing environment is connected to the outside, thus meeting general product needs. However, high-end or demanding applications, such as aerospace, automobiles, and medical treatment, require high physical properties of materials. High-performance composite materials, such as carbon fiber and PEEK, are required to meet special requirements such as high temperature resistance, high strength, lightweight, weather resistance, and biocompatibility. However, high-performance composite materials have high melting points and cannot be printed normally using a simple frame-type FDM 3D printing device. Based on this, the utility model provides a single-nozzle high-performance composite material 3D printing device. Utility Model Content
