| Abstract Scope |
As 3D-printed objects increase in size and complexity, so do the time and resources required to produce them. Thus, there is a need to assemble and repair large, multicomponent structures. For this reason, we developed a composite filament that can be used to attach and detach complex plastic parts with microwave heating. The composite is composed of a PETG matrix filled with a microwave-absorbable carbon nanomaterial. The composite is printed directly onto virgin PETG structures during fabrication, allowing us to engineer regions of localized microwave absorption. It is necessary to point out that our composite material heats at a significantly higher rate than the virgin PETG, which naturally absorbs microwave radiation. To this end, we suggest that PETG parts modified with the composite layer can be attached and detached from one another with minimal deformation of the attached parts. |
