Cold Plasma-Enabled Interface Engineering and In-Situ Functionalization of Printable Feedstocks in Additive Manufacturing: Mechanisms, Materials, and Applications.

Additive‑manufacturing parts often suffer from weak adhesion between layers, poor bonding at interfaces, and limited surface functionality of the feedstock materials. This research looks at how cold plasma can be used to engineer those interfaces directly on the feedstock. Non‑thermal (cold) plasma treatment can change the surface chemistry and texture of polymer, ceramic, or metal powders and filaments without affecting their bulk properties. The work evaluates how the treatment adds functional groups, raises surface energy, and improves the bonding behavior of the modified feedstock. Both computer simulations and lab experiments can be built to study how plasma particles interact with the material and how fast the surface changes occur. The

study also examines how plasma settings—such as the type of gas, the exposure time, and the power density—impact the mechanical strength and interfacial shear strength of the printed parts. In the end, the project creates a step‑by‑step framework for preparing feedstock with cold plasma. This approach offers a practical way to boost the structural integrity and multi‑functional performance of components made by selective laser sintering or stereolithography.
