Feasibility and Performance of Fully Additive Manufactured Light Bulbs

Additive manufactured electronics allows the development of highly integrated and personalized products. This work investigates the feasibility and performance of fully additive manufactured light bulbs that operate at mains voltage (230 V AC). The printing of the conductive traces, curing and pick & place of SMT components are combined in a single machine. Particular focus lies on the interconnection technology for the electronic components by printing conductive paste and dispensing adhesives. Furthermore, the thermal management and the reliability of the light bulbs are investigated.
