This pen prototype was created in the style of one of my design heros, Shiro Kuramata, for Bill Burnett’s Formgiving class. The three-part acrylic cast block was milled, polished and drilled. The pen was turned on a lathe and annodized. This was my first attempt at acrylic casting. My advice? Outsource this process. Even cured under vacuum it was difficult to get very good results.
