Abstract

Silicone, a commonly used household and construction adhesive, filler, or sealant, is also known for its flexibility, thermal stability, and insulating properties. It is viable as a conformally 3D-printed elastomeric matrix for flexible electronics and biomedical applications. Since most of the popular 3D printing methods use precise print specifications and defined resolution, this study explored the 3D printability of commercial silicone adhesives via a paste extrusion setup. Its viscoelastic and composition properties including the dimensional accuracy and mechanical properties of printed objects using controlled print parameters have been investigated. These experimental processes in 3D printing should pave the way in using materials originally intended for household use. Graphical Abstract: [Figure not available: see fulltext.]
