Circuit Printing with Squink
Squink inkjet prints low resistivity conductive inks and dielectric insulating inks so that you can prototype Printed Circuit Boards (PCBs) in minutes on a variety of stiff and flexible substrates. As a Circuit Printer, Squink sequentially prints conductive traces and then insulating layers, leaving gaps in the dielectric to act as vias and allow electricity to flow between layers.
Instead of waiting for weeks or shelling out thousands for factory-made PCBs, load Gerber or image files (JPEG, BMP, PNG) into the printer's web interface and have electronic circuit boards printed in a variety of substrates in minutes! Think of the possibilities with printing flexible lighting on clear films, creating flexible multilayered circuits, or teaching your students the fine art of PCB prototyping and design - all of this

"We are conducting research into combining electronics with additive manufacturing. The Squink’s ability to print circuit traces from PCB design software (we use Eagle and KiCad currently) is important to us. We are using it as a research tool to print traces onto a variety of substrates...[ ] ... The Squink is a very nice and well-engineered tool for the price point."
