We developed an out-of-oven additive manufacturing (AM) technique to rapidly print and cure thermosetting carbon fiber reinforced composites (CFRCs) using dielectric barrier discharge (DBD). Conventionally, CFRCs are produced by automated fiber placement machines (AFPs) that use molds and oven treatments to cure CFRCs in the desired shape. AM allows for on-the-fly printing and curing of CFRCs without
