Reactive Inkjet Printing

What is reactive Inkjet Printing?

Reactive inkjet printing (RIJ) describes the process of printing two or more inks on a substrate in the same location that react with eachother and produce a new product via a chemical reaction or conformal change in the molecular structure such as is the case when printing regenerated silk fibrion and methanol.

The diagram below shows the process of printing 3D silk microrockets via a Layer-By-Layer (LBL) reactive inkjet printing approach. This work is described in detail in “Reactive Inkjet Printing of Biocompatible Enzyme Powered Silk Micro‐Rockets”
