The ‘Printed Bulbs’ series explores new forms for light bulbs that reimagine the conventional ‘Edison bulb’ with a specialized 3D printing process. Within the clear bulb material internal structures are carefully designed to guide and reflect light. Internal bubbles are precisely created by slowly closing up small self-supporting air gaps. Light from the LED is reflected off the bubbles to create unique illumination patterns. Light pipes are used to guide light from point to point using a secondary material. Light enters and reflects continuously through the pipe before exiting at the other end. These techniques can be fabricated entirely in a 3D printer to enable new form-factors for lighting design. The finished bulb is attached to a universally compatible energy-efficient LED light socket. Each light bulb can be attached to any existing lighting fixture, such as a chandelier or desk lamp, or used individually as a pendant lamp or free-standing light.
