    Our amazing interns Jessica and Brian took the project from there. Jessica painted the 3D printed snacks so realistically that our office cleaner threw them in the compost overnight. These are hand-painted, 3D printed duplicates of Doritos, Cheetos, and Ruffles!

    These went straight into our @formlabs 3D printer, which produced exact duplicates (except for the otherworldly colors…)
