Abstract
A contact pin printhead for microfluidic array spot printing can include a printhead chassis with a plurality of micro-pins insertable within respective sockets in the printhead chassis. An individual micro-pin can include a micro-pin tip that can be individually biased in a distal direction toward a target substrate via an elastic mechanical biaser associated with the micro-pin. An individual micro-pin can deposit fluid carried within a cavity therein and onto a target substrate during physical contact therewith at a micro-pin tip. Also, an individual micro-pin can retain fluid carried within the cavity, without depositing, absent physical contact at the micro-pin tip.
