Abstract

This article presents initial results from a research project on the design and fabrication of a 3D-printed guitar. Specifically, it introduces and analyzes a modular model optimized for production with standard desktop printers. The objective is to make the model known while reflecting on the digital design process and additive manufacturing techniques, emphasizing their key intersections and differences with traditional lutherie. To this end, the study situates itself in the current context by outlining the state of the art in the application of digital fabrication to guitar construction. It then details the design, materials, and manufacturing decisions that guided the development of the model, including modularity and dimensions. The article identifies the main strengths and weaknesses of the model and proposes changes to be implemented in a second version. Finally, it reflects on future explorations and the anticipated impacts on local lutherie and on research into the vibroacoustic response of string instruments. It should be noted that this work focuses on the structural aspects of the model, which must be optimized before addressing the instrument's timbral qualities. A vibroacoustic analysis of the guitar is not included here, as it forms part of ongoing research.
