Abstract Scope |
Fused Deposition Modeling (FDM) 3D printing often employs a scanning-based infill strategy , leading to slow infill speeds and inconsistent infill density. This paper presents a new cooperative 3D printing system that combines molding and injection infill instead of conventional layer-by-layer deposition to enhance printing efficiency and consistency. The system utilizes two SCARA printers: one with a soft gel printhead for molding and another with a UV-curable resin printhead for injection infill. The method begins with the gel printer 3D printing the outline for certain layers as a temporary mold, into which the resin printer injects resin and cures it, and the cycle repeats to build the final part. Then the gel mold is removed by melting, revealing a solid resin structure. This method introduces a novel approach to additive manufacturing, results demonstrate that it can print complex geometries with good quality, reducing production time compared to FDM 3D printing. |
