AB - Moving beyond UV curing systems opens new potential application spacessuch as biological, portable printing solutions, as well as innovative chemistriesand material properties. A novel visible light printer is proposed for the rst timeusing green Digital Light Processing (gDLP) at a wavelength of 514 nm. GreenLED lights are integrated into a commercial desktop DLP printer to 3D printhydrogels with complex designs at high resolution. A workow process is pre-sented to develop and optimize formulations for gDLP, resulting in two novel in-house photoresin formulations made specically for green light printing. Theseformulations comprise PEGDA 700 with and without acrylamide, using a type IIphotoinitiating system of Eosin Y, triethylamine, and N-vinylpyrrolidone. Thephotoresins are optimized to achieve highly vascularized lattice prints by mod-ulating layer light exposure, chemical components, and photoinitiator concen-trations. The gDLP successfully printed hydrogels with a layer height of 50 mand feature dimensions as small as 0.3 mm by adjusting light duration per layer.3D printed hydrogels using both formulations are tested for varying designcomplexity, including ISO/ASTM standards, and evaluated with optical imag-ing, SEM, and mechanical testing. This study highlights gDLP technology’s po-tential for diverse applications in tissue engineering and sustainable materials.
