Additive manufacturing of metals and ceramics using hybrid fused filament fabrication

The present review elaborates about the intricacy being associated with the intensification of hybrid fused filament fabrication (FFF)-based process for additive manufacturing (AM) of metal and ceramic components. Hybridization of FFF and metal injection moulding enables sustainable and cost-efficient additive manufacturing of complex parts. Being a hybrid process, it involves optimization of various interlinked parameters; for this reason, the present review deliberately provides analysis of consolidated and comparative information of research work previously carried out for this process. As conclusively perceived, the present perspective of this review provides an approach of incorporating FFF-based hybrid AM technique, with benefits such as reduced capital expenditure, ease in processing and ability to manufacture parts from distinct variety of materials like metals, ceramics, polymers, etc., using the same setup.
