An interview with Ariel Briner of Cartesian Co
Chris Briner, co-founder of Cartesian Co, explains how his company created the Argentum, a desktop circuit board printer that uses modified HP inkjet cartridges to print conductive silver traces via a two-part chemical reaction. He details the challenges of scaling production from a Kickstarter campaign, including managing the shelf life of corrosive silver nitrate and ascorbic acid inks, and the technical hurdles of achieving industry-standard resolution and multi-layer capabilities. Briner also discusses the company's move from Australia to Brooklyn to be near the 3D printing hub, their bootstrapping philosophy, and the regulatory landscape for startup fundraising.
