Tools: Fountain Pen Based

From Fab @ Home

A fountain pen tool is a deposition tool which operates exactly like a fountain pen. A compliant (flexible) nib or tip is dragged over the surface on which the material is to be deposited. The nib has a fine channel down which fluid flows by capillary action. The fluid needs to be carefully filtered, and of low viscosity (about like water). The fountain pen tool can achieve very high resolution (limited by the size of the nib tip, and the surface energy of the fluid (the wettability) on the substrate or previous layer. A fountain pen tool is well-suited to drawing electronic circuits using conductive inks, organic polymer semiconductors, etc. speech writing service
