Enabling Recycling of Multi-Material 3D Printed Objects through Computational Design and Disassembly by Dissolution

要旨

Multi-material 3D printing combines the functional properties of different materials (e.g., mechanical, electrical, color) within a single object that is fabricated without manual assembly. However, this presents sustainability challenges as multi-material objects cannot be easily recycled. Because each material has a different processing temperature, considerable effort must be used to separate them for recycling. This paper presents a computational fabrication technique to generate dissolvable interfaces between different materials in a 3D printed object without affecting the object’s intended use. When the interfaces are dissolved, the object is disassembled to enable recycling of the individual materials. We describe the computational design of these interfaces alongside experimental evaluations of their strength and water solubility. Finally, we demonstrate our technique across 9 multi-material 3D printed objects of varying structural and functional complexity. Our technique enables us to recycle 89.97% of the total mass of these objects, promoting greater sustainability in 3D printing.
