How does Direct Ink Writing work?​

Direct Ink Writing (DIW), also known as “robocasting”, is a cutting-edge additive manufacturing technique that enables the precise deposition of inks or pastes to create complex three-dimensional structures. It functions much like 3D printing but offers greater versatility in terms of materials.


In DIW, a syringe or nozzle dispenses the ink, which can be composed of a variety of materials, including metals, ceramics, polymers, and even biological substances like cells or biocompatible gels. The printer follows a computer-generated design to create intricate and customized objects layer by layer.
