Research Highlights

• Solution intercalation improves dispersion quality of MWCNT nanocomposite resin.
• Stereolithography employing the resin enables highly precise and conductive backbones.
• 0.6-wt% MWCNT in the nanocomposite show an electrical conductivity of 0.071 S/m.
• 3D-printed objects maintain a high dimensional accuracy verified with the IT grade.
• Complex 3D metamaterial and multi-scale capacitive sensors demonstrate the manufacturing capability.
