In his YouTube video titled “How I Built a Real Movie Star Robot,” DeWitt shows the entire process. He 3D printed the parts, carefully hand-sanded each piece to smooth perfection, and applied a primer coat. Then came the hand-painting. But he didn’t stop there.
To give Newt a realistic, lived-in look, DeWitt used special weathering techniques. This gave the robot a slightly worn and rugged appearance—making it feel like part of the real world, not just a fresh-off-the-shelf prop.
