3D printed rPETG applications for interior design: A case study

Abstract. The use of recyclable filaments to produce 3D models using the Fused Filament Fabrication (FFF) method is increasingly promoting sustainability and innovation, compared to traditional filaments. The continuous improvement of the characteristics of this type of filament contributes to the control of their mechanical properties and especially their strength. At the same time, their compatibility with existing 3D printing technologies encourages their integration into the manufacturing sector. Polyethylene terephthalate glycol (rPETG) is one of the most popular recyclable materials in recent years. In addition to promoting the circular economy, it also offers new possibilities in product manufacturing. It can be used as a material for the 3D fabrication of products such as household items and office supplies. The present work focuses on the design and fabrication of handles used in cabinets and drawers through the parametric design of a kitchen island, highlighting the choice of rPETG as suitable material for their fabrication. The aim is for the final everyday object to be adaptable to different types of cabinets. In its own way, it offers ease, comfort, and safety while emphasizing the overall style of the furniture and harmonizing with the rest of the space.
