About Us

SonoPlot designs and sells Microplotter® materials dispensing systems for drawing features as small as 10 to 20 microns. Our patented ultrasonic dispensing technology enables true contiguous lines for superior conductive traces and enables the deposition of a wide range of materials, including solutions containing graphene, carbon nanotubes, nanoparticles, and polymers. This technology allows the Microplotter® to print inks with viscosities up to 450 cP without the hassle of tuning them to the printer. Integrated digital video and precise positioning allow for accurate alignment and dispensing on substrates. The Microplotter® systems provide unparalleled price per capability in the market.
