Spiral inductor fabricated by 3D additive manufacturing

摘要

This paper presents spiral inductor fabricated by 3D additive manufacturing. The inductor was made with conductive epoxy silver based paste which was injected in spiral channel fabricated in polylactide (PLA) substrate (model) using additive manufacturing technology. The fabricated structure has value of effective inductance around 415 nH, maximum quality factor around 12 and outer dimension diameter 24 mm. The prototype results show good characteristics of 3D additive manufactured spiral inductor and demonstrate an innovative approach to fabricate low-cost, passive devices such as an inductor.
