Additive manufacturing (also referred to as 3D printing) technologies have found applications in a wide range of industries such as aerospace and automobile, due to their superior manufacturing capability and design freedom enabled by the layer-wise fabrication method. Over the past decade, the adoption of additive manufacturing has evolved from rapid prototyping and tooling to rapid manufacturing of end-use products, which, on the other hand, introduced new challenges for reducing the environmental impacts and enhancing resource sustainability of additive manufacturing from a lifecycle perspective. In current literature, some research efforts have been conducted on waste recycling aiming to close to material loop and relieve the environmental consequences caused by both pre- and post-consumer wastes generated from additive manufacturing. This article provides an overview of the state-of-the-art on additive manufacturing waste recycling and identifies critical gaps for future research in this field.
