This sweet wearable Ultron mask was made through the combined efforts of Jacob Morin, Michael Ruddy of Hero Complex, and Sean Shaw of Shawshank Cosplay and Props. Jacob made the 3D model, Michael printed the helmet and Sean made the final mask based on the 3D printed one.
Michael used a gMax 1.5XT to print the mask, which took about 83 hours to print. Sean sanded down the 3D printed mask then made silicone molds out of the parts. The finished mask shown in these pictures were casted from those molds.
Sean will be making more masks to sell, but he says he needs to work on the eyes before he starts taking orders. Keep an eye on his Facebook page if you want to buy one from him.
