Abstract

We report a facile fabrication method of curved mirror with 3D printed plastic mold. Polylactic acid (PLA) is used as material for plastic mold. Polydimethylsiloxane (PDMS) replica is obtained from PLA mold, followed by planarization with spin-coating of additional PDMS. After ultraviolet (UV) treatment of smoothened PDMS replica, aluminum (Al) layer is deposited by thermal evaporation. Due to smoothened surface of PDMS replica, Al layer shows clear reflected image without perceptible lines, thereby functioning as a curved mirror. We expect that our curved mirror will be applicable to display and imaging devices.
