This study explores the enhancement of interlayer strength in ABS parts using a novel apparatus mounted on a 3D printer. The apparatus utilizes a needle immersion technique, where the depth of the needle is carefully adjusted based on the temperature profile of the printed layers. The study focuses on how the cooling behavior of the printed wall affects the needle’s immersion depth and its alignment with layer thickness. Results indicate that maintaining the layers above the glass transition temperature allows for effective needle penetration, improving fiber alignment and intermixing between layers. This leads to significantly enhanced vertical strength and interlayer adhesion. The findings offer valuable insights for optimizing fiber-reinforced polymer composites in additive manufacturing, with potential applications in advanced engineering fields.

摘要

This study explores the enhancement of interlayer strength in ABS parts using a novel apparatus mounted on a 3D printer. The apparatus utilizes a needle immersion technique, where the depth of the needle is carefully adjusted based on the temperature profile of the printed layers. The study focuses on how the cooling behavior of the printed wall affects the needle’s immersion depth and its alignment with layer thickness. Results indicate that maintaining the layers above the glass transition temperature allows for effective needle penetration, improving fiber alignment and intermixing between layers. This leads to significantly enhanced vertical strength and interlayer adhesion. The findings offer valuable insights for optimizing fiber-reinforced polymer composites in additive manufacturing, with potential applications in advanced engineering fields.
