3D printing of uv-curable polyacrylamide hydrogel loaded with lignin
This study aims to develop UV-curable polyacrylamide (PAM) hydrogels loaded with lignin and assess the feasibility of 3D printing using the Digital Light Processing (DLP) 3D printing technique. Lignin nanoparticles were incorporated into the acrylamide resin at varying concentrations ranging from 0 to 2.5 wt%, and subs...
