Circuit Printing

What is Circuit Printing?


Direct Ink Writing (DIW) is method of additive manufacturing that involves the use of liquid-phase inks deposited in small nozzles to print on a digitally fabricated path. The flow rate, temperature, mediums and path must all be the ideal requirements for successful printing. It can be said that Direct ink writing combines deposition of inks and direct extrusion methods. DIW is used in electronic components such as wire and antenna design by effectively 3D printing electric circuits and electrodes. It is extremely useful in design prototyping and optimization strategies by speeding up the product realization and validation.


Direct ink Writing uses several different forces such as screws, pneumatics and pistons to drive the inks to create the design. This ensures a  high level of flexibility and durability of the printed parts. The nozzle pressure and speed are also relevant factors that we consider. Direct ink writers usually comprise four working components. A dispenser and a regulated nozzle, a three-dimensional axis to achieve the desired shape, and computer software to craft the digital path that serves as a pathway for the liquids/gels. It can be used efficiently with a variety of material segments such as polymers, inks and ceramic pastes.



In the medical sector, these PCBs have found their way into MRI machines, X-ray machines, scanners and more. The compatibility and size of rigid-flex circuit boards make them the best low-cost option to reduce the size of medical products such as hearing aids, pacemakers, and colonoscopy cameras. These PCBs eliminate the need for messy components like flex cables, enabling more space and removing unnecessary intricacy.
