Rhapso: 自動將纖維材料嵌入 3D 打印以增強互動性

Abstract

我們提出了Rhapso，一種在打印過程中將多種連續纖維材料嵌入3D物體的3D列印系統。這種方法使得低成本熱塑性3D列印可以直接整合拉伸強度、光傳輸、導電性和熱產生等特性。這些功能性物體可以具有複雜的驅動、自我組裝和感測能力，且幾乎不需要手動干預。為了實現這一點，我們改造了一台低成本的熱熔融層積（FFF）3D列印機，在列印床上方添加掛有纖維線卷機構的齒輪環，並由一步進馬達控制齒輪環。除了硬體之外，我們還提供了分析軟體，用於精確的纖維放置，生成用於控制列印印機操作的 G代碼。為了展示我們系統的多功能性，我們展示了幾個應用，展示了其廣泛的設計潛力。此外，我們提供了全面的文檔和開放設計，使他人能夠複製我們的系統並探索其可能性。

We introduce Rhapso, a 3D printing system designed to embed a diverse range of continuous fiber materials within 3D objects during the printing process. This approach enables integrating properties like tensile strength, light transmission, electrical conductivity, and heat generation directly into low-cost thermoplastic 3D prints. These functional objects can have intricate actuation, self-assembly, and sensing capabilities with little to no manual intervention. To achieve this, we modify a low-cost Fused Filament Fabrication (FFF) 3D printer, adding a stepper motor-controlled fiber spool mechanism on a gear ring above the print bed. In addition to hardware, we provide parsing software for precise fiber placement, which generates G-code for printer operation. To illustrate the versatility of our system, we present applications that showcase its extensive design potential. Additionally, we offer comprehensive documentation and open designs, empowering others to replicate our system and explore its possibilities.
