Protocol

Planar and three-dimensional printing of conductive metallic inks is described. Our approach provides new avenues for fabricating printed electronic, optoelectronic, and biomedical devices in unusual layouts at the microscale.

Difficulty
intermediate
Total time
~4–8 hours per complete fabrication cycle (ink preparation + printing + curing)

Steps

1
Prepare highly concentrated silver nanoparticle inks

Synthesize or process silver nanoparticles to achieve high concentration suitable for direct-write printing. Optimize ink viscosity and particle suspension stability for reliable deposition.
