FABRICATION OF FDM 3D PRINTED MODELS WITH NON-ASSEMBLY ARTICULATED JOINTS USING MATERIAL SEPARATION TECHNIQUES
Abstract
Additive manufacturing is used in multiple industries to create prototypes, visual models and objects with complex geometries. Being able to fabricate an object layer by layer, additive manufacturing offers the possibility to create objects with embedded, non-assembly joints. With Fused Deposition Modeling (FDM), one of the most common and accessible 3D printing processes, minimizing joint clearance for models with non-assembly joints presents a challenge, especially in the case of consumer-grade desktop machines. This paper presents methods of creating joints which are initially fused following the fabrication process and are broken free during post-processing. This results in tighter joint clearance, useful in the creation of articulated visual models, prototypes or functional parts. The reduction of contact surface bonding strength is achieved through various methods, such as reducing contact area, depositing a thin film of material between the objects or variation of layer or gap thickness.
