We propose a two-step strategy to achieve selective gold metallization for the realization of reflective micro-optics with 3D printing. We apply this strategy to fabricate right-angle prism mirrors, used to create counter-propagating beam optical traps. In combination with a holographic optical trapping setup, dynamic optical traps are obtained using a single low-NA microscope objective. We print the prisms on standard glass coverslips to create integrated optical trapping chips. We show the automatization of alignment between prisms and masks by a computer vision software.
