Recently, short carbon fiber-reinforced plastic (SFRP) has been selected as a filament material to improve the strength of components fabricated by material extrusion (ME). However, despite the improved material properties, the weak interlayer bondin

Binder jetting (BJ) leads to low mechanical properties and high porosity because it uses binders to selectively bind powder materials. To overcome the poor characteristics of BJ parts, infiltration is a generally applied post-process; however, it res

Owing to the deposition mechanism, parts fabricated by polymer-based powder bed fusion (PBF) contain numerous porosities, which deteriorate mechanical properties. To address this problem, a warm isostatic press (WIP) process was adopted to control th

Material extrusion (ME) using a filament including metal powders has recently attracted considerable attention because it allows the production of metal parts at low cost. However, like other additive manufacturing processes, metal ME suffers from th

Owing to the deposition mechanism, parts fabricated from the material extrusion (ME) process have intrinsic air gaps that negatively impact their mechanical properties. Thus, the amount of air gaps should be minimized. In this study, a warm isostatic

Selective laser melting (SLM) process based on metallic powders has been broadly adopted for its higher accuracy. In the SLM process, the building of a process window is a fundamental work for fabricating a full-dense part for a new material. Single-

One of the most significant barriers to the broad adoption of additive manufacturing (AM) is the qualification of AM produced parts. With the high market competition, quality has become the market differentiator for products and services. To maintain
